Flutter TextFormField pointer overlapping the text - flutter

When using TextFormField in Flutter and having the form prefilled with text, when I tap somewhere on it in order to start editing the text, I get the little rain drop pointer right over the text:
I expect it to appear a little bit below the form. Something like this:
Here is the code:
Container(
height: 40.0,
child: TextFormField(
style: TextStyle(
fontSize: 17,
),
controller: serverAddressController,
decoration: InputDecoration(
border: OutlineInputBorder(
borderRadius: new BorderRadius.circular(10.0),
),
),
onChanged: (value) {
serverAddress = value;
changesSaved = false;
},
textInputAction: TextInputAction.next,
onFieldSubmitted: (_) {
FocusScope.of(context)
.requestFocus(daysBackFocusNode);
},
),
),
How do I do it?

you've set Container height to low but didn't reduce content paddings
just add contentPadding property
decoration: InputDecoration(
contentPadding: EdgeInsets.only(left: 16, right: 16),
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(16.0),
),
),

How to have the label and input text within the same container

I am trying to recreate this textfield design
As you can see the label/hint text is centered when it is not focused and once in focus, the input text and the label/hint text are also centered within the border.
What I tried to recreate this design is first to create the textfield, remove all the borders, and wrap it with a container, and finally play with content padding but I either get text input text off-centered or I get the label/hint text off-centered.
Images below show how the label/hint is off-centered
BUT when in focus
Here sample code
Container(
height: 60,
padding: EdgeInsetsDirectional.only(
start: width * 0.038,
end: width * 0.038,
),
decoration: BoxDecoration(
border: Border.all(
color: state.hasError
? Constant.errorColor
: Constant.greyColor,
width: 1),
borderRadius: const BorderRadius.all(Radius.circular(10)),
),
child: TextField(
inputFormatters: inputFormatter,
controller: controller,
onSubmitted: onSubmitted,
onChanged: state.didChange,
focusNode: focusNode,
textInputAction: textInputAction,
keyboardType: keyboard,
obscureText: obscure,
decoration: InputDecoration(
labelText: label,
alignLabelWithHint: true,
labelStyle: Constant.hintText.copyWith(
color: state.hasError
? Constant.errorColor
: Constant.greyColor,
fontSize: 14,
),
hintText: hint,
hintStyle: Constant.hintText.copyWith(fontSize: 14),
contentPadding: null,
// contentPadding: EdgeInsetsDirectional.only(
// bottom: 7.5,
// ),
border: InputBorder.none,
focusedBorder: InputBorder.none,
enabledBorder: InputBorder.none,
errorBorder: InputBorder.none,
disabledBorder: InputBorder.none,
),
),
),
You could create a custom text box:
Container(
Column(
children: [
Text("insert label text", textAlign: TextAlign.start)
TextField(
...
// no labelText
// remove decorations
)
]
)
);

Horizontal scroll in TextFormField flutter on text input

I have an email input text field when I write more text than the width of this input, the rest of the text is not visible. Is there a way to have a horizontal scroll as I input into this text form field?
The following image describes the behavior I want.
Edit: My Code
Container(
width: 270,
height: 42,
child: new TextFormField(
validator: (val) => val.isEmpty ? 'Enter an email' : null,
decoration: new InputDecoration(
icon: Icon(
Icons.email_outlined,
),
labelText: 'Email',
border: new OutlineInputBorder(
borderRadius: new BorderRadius.circular(25.0),
borderSide: new BorderSide(),
),
),
keyboardType: TextInputType.emailAddress,
onChanged: (val) {
setState(() => email = val);
},
),
),
This is what happens when I type beyond the width of the TextFormField
There are two ways to go about this:
You can add the isDense property to your TextFormField, in which case your code will look like this:
Container(
width: 270,
height: 42,
child: TextFormField(
textAlignVertical: TextAlignVertical.center,
validator: (val) => val!.isEmpty ? 'Enter an email' : null,
decoration: new InputDecoration(
isDense: true,
icon: Icon(
Icons.email_outlined,
),
labelText: 'Email',
border: new OutlineInputBorder(
borderRadius: new BorderRadius.circular(25.0),
borderSide: new BorderSide(),
),
),
keyboardType: TextInputType.emailAddress,
onChanged: (val) {
setState(() => email = val);
},
),
),
This fixes the problem to an extent, however if font that extends lower(like commas, semicolons etc. still get clipped off). The next method fixes this:
Use the contentPadding property, since if you check the source code, all isDense does is modify the contentPadding property's value. This is some of the actual code behind isDense:
if (decoration!.filled == true) { // filled == null same as filled == false
contentPadding = decorationContentPadding ?? (decorationIsDense
? const EdgeInsets.fromLTRB(12.0, 8.0, 12.0, 8.0)
: const EdgeInsets.fromLTRB(12.0, 12.0, 12.0, 12.0));
} else {
// Not left or right padding for underline borders that aren't filled
// is a small concession to backwards compatibility. This eliminates
// the most noticeable layout change introduced by #13734.
contentPadding = decorationContentPadding ?? (decorationIsDense
? const EdgeInsets.fromLTRB(0.0, 8.0, 0.0, 8.0)
: const EdgeInsets.fromLTRB(0.0, 12.0, 0.0, 12.0));
}
As you can see, all Flutter does behind the scenes is assign hardcoded values to your arguments based on the parameters you've passed. In your case, the best configuration seems to be:
Container(
width: 270,
height: 42,
child: TextFormField(
textAlignVertical: TextAlignVertical.center,
validator: (val) => val!.isEmpty ? 'Enter an email' : null,
decoration: InputDecoration(
contentPadding: EdgeInsets.fromLTRB(12.0, 8.0, 12.0, 8.0),
icon: Icon(
Icons.email_outlined,
),
labelText: 'Email',
border: new OutlineInputBorder(
borderRadius: new BorderRadius.circular(25.0),
borderSide: new BorderSide(),
),
),
keyboardType: TextInputType.emailAddress,
onChanged: (val) {
setState(() => email = val);
},
),
),
The above code fixes your issue, but might create more problems if your font height changes.

Flutter when text is bigger than input, text disappears

The problem is that when the text is bigger than the input size, the text just disappears and I don't know why.
Here is my code:
TextField(
focusNode: _focusEmailNode,
controller: _emailController,
decoration: InputDecoration(
border: OutlineInputBorder(),
enabledBorder: OutlineInputBorder(
borderSide: BorderSide(color: txtEmailBoder),
),
hintText: 'Email',
),
After searching through many sites, I finally got a solution. You can solve this problem by giving decoration and maxlines in the textfield. Give isDense as true in InputDecoration
Example:
Container(
height: 20,
width: 100,
child: TextFormField(
maxLines: 1,
decoration: InputDecoration(
isDense: true,
contentPadding: EdgeInsets.fromLTRB(5.0, 1.0, 5.0, 1.0),
),
onChanged: (value) {
print(value);
},
),
);
if you don't give content padding then your text will be cut from the middle, like below.
Be careful when you give padding, you should give padding as needed by your textfield's height. If you give wrong padding then also your text will be invisible.
You need to add
contentPadding: EdgeInsets.zero
to your InputDecoration
Give text field an input formatter with desired length of the text like this:
inputFormatters: [
LengthLimitingTextInputFormatter(50),
],
And then have content padding set to like this :
contentPadding: EdgeInsets.fromLTRB(5.0 , 20.0 , 5.0 , 20.0),
Widget build(BuildContext context) {
return Scaffold(
body: Container(
padding: EdgeInsets.fromLTRB(5.0, 50, 5.0, 10.0),
alignment: Alignment.center,
child: TextField(
decoration: InputDecoration(
border: OutlineInputBorder(),
enabledBorder: OutlineInputBorder(
borderSide: BorderSide(color: Colors.blueAccent),
),
hintText: 'Email',
),
)));
}
To Prevent this disappearing use decoration as InputDecoration.collapsed(hintText: "Search Customer")
Full Code is TextField(decoration : InputDecoration.collapsed(hintText: "Search Customer"), textCapitalization: TextCapitalization.sentences)

How do I remove content padding from TextField?

I am new to flutter and I am creating login form, for that I have used TextField and added prefix icon but I am getting some extra spaces in between textfields (user id and pin) and before the prefix icon. I have also tried InputDecorationTheme but it didn't work.
Please let me know how can I remove or reduce the space.??
Below is my code:
TextField(
maxLength: 8,
keyboardType: TextInputType.number,
decoration: InputDecoration(
hintText: hint,
hintStyle: TextStyle(fontSize: 12.0),
prefixIcon: Icon(icon),
counterText: '',
),
)
Update (August 2022): still the same as of flutter 3.0.5
Update (April 2021): still work in flutter 2.0.4
As of flutter 1.17.5 (and still the same in 2.X) to completely remove or manipulate the padding manually, first you must set isDense: true and then you can adjust the contentPadding as you wanted or apply padding on the parent widget instead.
// using theme
ThemeData(
inputDecorationTheme: InputDecorationTheme(
isDense: true,// this will remove the default content padding
// now you can customize it here or add padding widget
contentPadding: EdgeInsets.symmetric(horizontal: 0, vertical: 0),
...
),
)
// per widget
TextField(
decoration: InputDecoration(
isDense: true,
contentPadding: EdgeInsets.symmetric(horizontal: 0, vertical: 0),
...
),
)
As mentioned in the comment by Ataberk you can also use contentPadding: EdgeInsets.zero
TextField(
decoration: InputDecoration(
isDense: true,
contentPadding: EdgeInsets.zero,
...
),
)
You can use contentPadding of InputDecoration.
Here is sample code
TextField(
maxLines: 8,
decoration: InputDecoration(
contentPadding: EdgeInsets.symmetric(vertical: 5),
labelText: 'Description',
labelStyle: txtHintStyle,
)
)
I was able to easily achieve that by adding prefix constraints to the prefixIcon and wrapping the prefixIcon with padding like this
TextFormField(
enabled: true,
decoration: InputDecoration(
prefixIconConstraints:BoxConstraints(minWidth: 23, maxHeight: 20),
prefixIcon: Padding(
padding: const EdgeInsets.only(right: 20),
child: Icon(
Icons.email,
color: clockColor,
),
),
hintText:"Email Address"
hintStyle:TextStyle(color: hintColor, fontSize: 14),
),
),
heres the output,hope this helps
I come a bit late, but the only thing you have to do is to use negative padding :
TextField(
decoration: InputDecoration(
contentPadding: EdgeInsets.symmetric(vertical: -5),
labelText: 'Description',
)
)
By applying minus padding by using
transform: Matrix4.translationValues(-10.0, 0.0, 0.0),
put above line inside the icon container
TextFormField(
keyboardType: TextInputType.number,
style: new TextStyle(color: Colors.white, fontSize: 17),
decoration: new InputDecoration(
prefixIcon: Container(
transform: Matrix4.translationValues(-10.0, 0.0, 0.0),
child: Icon(
Icons.vpn_key,
color: Colors.white,
),
),
labelText: "Enter Password",
labelStyle: new TextStyle(color: Colors.white)),
),
You can try this hack by reducing height of TextField
SizedBox(
height: 44, // set this
child: TextField(),
)
You can use:
TextField(
maxLines: 1,
decoration: InputDecoration(contentPadding: EdgeInsets.only(bottom: -10.0))
)
That prefixIcon has already contained the padding of 12.0 according to documentation.
So you don't need to provide extra padding.
See this below explanation & code which you can find in input_decorator.dart.
The prefix icon is constrained with a minimum size of 48px by 48px,
but can be expanded beyond that. Anything larger than 24px will
require additional padding to ensure it matches the material spec of
12px padding between the left edge of the input and leading edge of
the prefix icon. To pad the leading edge of the prefix icon:
prefixIcon: Padding(
padding: const EdgeInsetsDirectional.only(start: 12.0),
child: myIcon, // icon is 48px widget.
)
I hope it will help.
TextField(
decoration: InputDecoration(
isDense: true, //Set this to true
contentPadding: EdgeInsets.symmetric(vertical: 0),
hintText: 'Description',
)
)
Setting isDense: true will give you full control of setting the contentPadding. Make sure to set the EdgeInsets. as your need.
I have try many ways but only worked fine for me.
If you want to remove the left padding of Prefix icon, Give prefixIconConstraints:BoxConstraints(maxHeight: 20) to InpuDecoration .
TextField(
autocorrect: false,
textAlignVertical: TextAlignVertical.bottom,
onSubmitted: (value) {
getXHelper.textFieldSubmit(value, type);
},
decoration: InputDecoration(
isDense: true,
prefixIconConstraints:BoxConstraints(maxHeight: 20) ,
hintText: placeHolder,
prefixIcon: Padding(
padding: const EdgeInsets.only(top: 0, right: 5, bottom: 0),
child: Icon(
icon,
size: 20,
),
),
suffixIcon: type == TextFieldType.password ? passShowButton : null,
),
controller: controller,
cursorColor: Colors.black,
style:
TextStyle(color: Colors.black, fontFamily: AppFontFamily.fontFamily),
);
Please check the screen shot
replace prefixIcon-> prefix
TextFormField(
decoration: InputDecoration(
prefix:Icon(
Icons.perm_identity_outlined,
color: AppColors.primary,
),
labelText:'UserName'
),
)
You can set This value for TextFeild
decoration: InputDecoration(
isDense: true,
contentPadding: EdgeInsets.symmetric(horizontal: 0, vertical: 0),
...
)
remove prefixIcon
Row(
children: [
//add icon
Icon(Icons.person,color: Colors.grey,),
Flexible(
child: TextFormField(
decoration: InputDecoration(
border: InputBorder.none,
hintText: 'User Id',
contentPadding: EdgeInsets.all(0.0),//add content padding
isDense: true,//add isDense
),
),
),
],
),
//add some space between two row
SizedBox(height: 10,),
Row(
children: [
Icon(Icons.lock,color: Colors.grey,),
Flexible(
child: TextFormField(
decoration: InputDecoration(
border: InputBorder.none,
hintText: 'Pin',
contentPadding: EdgeInsets.all(0.0),
isDense: true,
),
),
),
],
),
I had to achieve something similar but could not find perfect solution. Came up with and work around using Stack widget.
Widget _username(context){
return SizedBox(
height: 35,
child: Stack(
children: <Widget>[
Align(
alignment: Alignment.centerLeft,
child: Icon(
Icons.mail,
size: 20,
color: Theme.of(context).accentColor,
),
),
TextField(
style: TextStyle(
color: Colors.white
),
decoration: InputDecoration(
contentPadding: const EdgeInsets.symmetric(vertical: 11.0, horizontal: 33.0),
hasFloatingPlaceholder: false,
labelText: 'Username',
labelStyle: TextStyle(
color: Colors.white
),
enabledBorder: UnderlineInputBorder(
borderSide: BorderSide(
color: Theme.of(context).accentColor,
)
),
focusedBorder: UnderlineInputBorder(
borderSide: BorderSide(
color: Theme.of(context).accentColor,
),
),
),
),
]
),
);
}
SizedBox is used to control the vertical padding. For horizontal padding, Icon and TextField are stacked. This results overlapped TextField's label above Icon so contentPadding property is used to move the label to the right. With this I achieved following look.

How to change TextField's height and width?

How to customise TextField's width and height?
To adjust the width, you could wrap your TextField with a SizedBox widget, like so:
const SizedBox(
width: 100.0,
child: TextField(),
)
I'm not really sure what you're after when it comes to the height of the TextField but you could definitely have a look at the TextStyle widget, with which you can manipulate the fontSize and/or height
const SizedBox(
width: 100.0,
child: TextField(
style: TextStyle(fontSize: 40.0, height: 2.0, color: Colors.black),
),
)
Bear in mind that the height in the TextStyle is a multiplier of the font size, as per comments on the property itself:
The height of this text span, as a multiple of the font size.
When [height] is null or omitted, the line height will be determined
by the font's metrics directly, which may differ from the fontSize.
When [height] is non-null, the line height of the span of text will be a
multiple of [fontSize] and be exactly fontSize * height logical pixels
tall.
Last but not least, you might want to have a look at the decoration property of you TextField, which gives you a lot of possibilities
EDIT: How to change the inner padding/margin of the TextField
You could play around with the InputDecoration and the decoration property of the TextField. For instance, you could do something like this:
const TextField(
decoration: InputDecoration(
contentPadding: EdgeInsets.symmetric(vertical: 40.0),
),
)
I think you want to change the inner padding/margin of the TextField.
You can do that by adding isDense: true and contentPadding: EdgeInsets.all(8) properties as follow:
Container(
padding: EdgeInsets.all(12),
child: Column(
children: <Widget>[
TextField(
decoration: InputDecoration(
border: OutlineInputBorder(),
labelText: 'Default TextField',
),
),
SizedBox(height: 16,),
TextField(
decoration: InputDecoration(
border: OutlineInputBorder(),
labelText: 'Densed TextField',
isDense: true, // Added this
),
),
SizedBox(height: 16,),
TextField(
decoration: InputDecoration(
border: OutlineInputBorder(),
labelText: 'Even Densed TextFiled',
isDense: true, // Added this
contentPadding: EdgeInsets.all(8), // Added this
),
)
],
),
)
It will be displayed as:
Screenshot:
You can do it in many ways:
Using maxLines + expands:
SizedBox(
width: 240, // <-- TextField width
height: 120, // <-- TextField height
child: TextField(
maxLines: null,
expands: true,
keyboardType: TextInputType.multiline,
decoration: InputDecoration(filled: true, hintText: 'Enter a message'),
),
)
Using just maxLines:
Widget _buildTextField() {
final maxLines = 5;
return Container(
margin: EdgeInsets.all(12),
height: maxLines * 24.0,
child: TextField(
maxLines: maxLines,
keyboardType: TextInputType.multiline,
decoration: InputDecoration(filled: true, hintText: 'Enter a message'),
),
);
}
This answer works, but it will have conflicts when the input field is in error state, for a better approach and a better control you can use this.
InputDecoration(
isCollapsed: true,
contentPadding: EdgeInsets.all(9),
)
If you want to increase the height of TextFormField dynamically while typing the text in it. Set maxLines to null. Like
TextFormField(
onSaved: (newText) {
enteredTextEmail = newText;
},
obscureText: false,
keyboardType: TextInputType.emailAddress,
validator: validateName,
maxLines: null,
// style: style,
decoration: InputDecoration(
contentPadding: EdgeInsets.fromLTRB(5.0, 10.0, 5.0, 10.0),
hintText: "Enter Question",
labelText: "Enter Question",
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(10.0))),
),
Wrap TextField in SizedBox for the width
SizedBox(
height: 40,
width: 150,
child: TextField(),
)
You can try the margin property in the Container. Wrap the TextField inside a Container and adjust the margin property.
new Container(
margin: const EdgeInsets.only(right: 10, left: 10),
child: new TextField(
decoration: new InputDecoration(
hintText: 'username',
icon: new Icon(Icons.person)),
)
),
If you use "suffixIcon" to collapse the height of the TextField add:
suffixIconConstraints
TextField(
style: TextStyle(fontSize: r * 1.8, color: Colors.black87),
decoration: InputDecoration(
isDense: true,
contentPadding: EdgeInsets.symmetric(vertical: r * 1.6, horizontal: r * 1.6),
suffixIcon: Icon(Icons.search, color: Colors.black54),
suffixIconConstraints: BoxConstraints(minWidth: 32, minHeight: 32),
),
)
simply wrap the TextField() in SizedBox() and give the height of the sized box
use contentPadding, it will reduce the textbox or dropdown list height
InputDecorator(
decoration: InputDecoration(
errorStyle: TextStyle(
color: Colors.redAccent, fontSize: 16.0),
hintText: 'Please select expense',
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(1.0),
),
contentPadding: EdgeInsets.all(8)),//Add this edge option
child: DropdownButton(
isExpanded: true,
isDense: true,
itemHeight: 50.0,
hint: Text(
'Please choose a location'), // Not necessary for Option 1
value: _selectedLocation,
onChanged: (newValue) {
setState(() {
_selectedLocation = newValue;
});
},
items: citys.map((location) {
return DropdownMenuItem(
child: new Text(location.name),
value: location.id,
);
}).toList(),
),
),
Set minLines: null, maxLines: null and expands:true to let the TextField fill the height of its parent widget:
Container(
child: TextField(
minLines: null,
maxLines: null,
expands: true
)
)
Refere to these docs for the same:https://api.flutter.dev/flutter/material/TextField/expands.html
And for width, you can do this:
Container(
width: 100,
child: TextField(
)
)
to let the TextField fill its parent widget's width(100 pixels in this case)
Adjust Height using contentPadding instead of SizeBox or Container
Container(
width: width * 0.85,
child: TextFormField(
textInputAction: TextInputAction.next,
textAlignVertical: TextAlignVertical.center,
decoration: InputDecoration(
contentPadding: const EdgeInsets.symmetric(vertical: 10), //Imp Line
isDense: true,
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(5),
borderSide: const BorderSide(
width: 0.5,
color: Constants.secondaryColourLight,
)),
),),)
80k ka code hein 80k ka
Finally, I got my solution using this trick.
Provide Height and width of sizedbox and set expand the property to true. Also, set maxLines to null and minLines to null.
SizedBox(
height: SizeConfig.screenWidth * 0.1377,
child: TextFormField(
validator: validator,
enabled: isEnabled,
expands: true,
maxLines: null,
minLines: null,
),
);
TextField( minLines: 1, maxLines: 5, maxLengthEnforced: true)
int numLines = 0;
Container(
height: numLines < 7 ? 148 * WidgetsConstant.height: numLines * WidgetsConstant.height * 24,
child: TextFormField(
controller: _bodyText,
maxLines: numLines < 7 ? 148 : numLines,
keyboardType: TextInputType.multiline,
textInputAction: TextInputAction.newline,
onChanged: (String value) {
setState(() {
numLines = '\n'.allMatches(value).length + 1;
});
},
),
),
The perfect way to get rid of padding is to use InputDecoration.collapsed.
It wraps the GestureDetector with a Container and decorates the Container with as much Padding, Border, and Decoration as needed.
GestureDetector(
onTap: () => _focusNode.requestFocus(),
child: Container(
padding: const EdgeInsets.all(10),
decoration: BoxDecoration(
color: Colors.grey,
borderRadius: BorderRadius.circular(4),
),
child: TextField(
focusNode: _focusNode,
decoration: const InputDecoration.collapsed(
hintText: 'Search...',
border: OutlineInputBorder(
borderSide: BorderSide(
width: 0,
style: BorderStyle.none,
),
),
),
),
),
);
To display an icon, change the Container child to Row, and use Icon and a TextField wrapped with Expanded.
To increase the height of TextField Widget just make use of the maxLines: properties that comes with the widget. For Example:
TextField(
maxLines: 5
) // it will increase the height and width of the Textfield.
You can simply wrap Text field widget in padding widget.....
Like this,
Padding(
padding: EdgeInsets.only(left: 5.0, right: 5.0),
child: TextField(
cursorColor: Colors.blue,
decoration: InputDecoration(
labelText: 'Email',
hintText: 'xyz#gmail.com',
//labelStyle: textStyle,
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(5),
borderSide: BorderSide(width: 2, color: Colors.blue,)),
focusedBorder: OutlineInputBorder(
borderRadius: BorderRadius.circular(10),
borderSide: BorderSide(width: 2, color: Colors.green)),
)
),
),
You can change max
minLines: 4,
maxLines: 6,
Provide a maxLines and add a BoxConstraints with width and height in InputDecoration.
TextField(
maxLines: 10,
decoration: InputDecoration(
border: OutlineInputBorder(borderRadius: BorderRadius.circular(10)),
constraints: BoxConstraints.tightFor(width: 300, height: 100),
),
);
TextField(
decoration: InputDecoration(
border: OutlineInputBorder(borderRadius: BorderRadius.circular(10)),
constraints: BoxConstraints(maxHeight:48,maxWidth: 327,),
),
);
