I have TextFormField and I increased height of this field. I would like to start text from the left top corner and make that text will break at the end of the line. So if someone will put a lot of text, field will have X lines not only one.
How it looks now:
How it should looks like
Code:
TextFormField(
controller: contentController,
decoration: InputDecoration(
contentPadding: new EdgeInsets.symmetric(
vertical: MediaQuery.of(context).size.height * .10,
horizontal: 10.0),
border: OutlineInputBorder(),
hintText: 'Treść',
fillColor: Color(0xffffffff),
filled: true,
prefixIcon: Icon(Icons.topic_rounded),
),
validator: (value) {
if (value == null || value.isEmpty) {
return ErrorMessages.NO_CONTENT_MESSAGE;
}
},
),
There are a few things you can do:
You can add maxLines: desiredNumberOfLines and textAlignVertical: TextAlignVertical.top, to your TextFormField and wrap your prefix icon with Padding like this:
TextFormField(
textAlignVertical: TextAlignVertical.top,
decoration: InputDecoration(
prefixIcon: Padding(
padding: const EdgeInsets.only(bottom: 70.0),
child: Icon(
Icons.topic_rounded,
),
),
...
),
maxLines: 5,
...
),
You can wrap your TextFormField with a SizedBox widget and add expands: true to the text field, also you have to set minLines and minLines to null, because otherwise you get an error. The icon alignment can be the same as in the previous example with wrapping the icon with a Padding widget or you can do it the other way, which is shown in this example. It is done by using a prefix parameter instead of prefixIcon like this:
SizedBox(
height: 200,
child: TextFormField(
textAlignVertical: TextAlignVertical.top,
expands: true,
maxLines: null,
minLines: null,
decoration: InputDecoration(
prefix: Icon(
Icons.topic_rounded,
),
...
),
...
),
)
Choose a combination of text and icon alignment methods that works best for you.
You need to specify the height of your prefix icon by default it will be in the center. But to make it go on top you need to add Container() in which you will add your icon like this.
TextFormField(
minLines: 4,
keyboardType: TextInputType.multiline,
maxLines: 4,
decoration: InputDecoration(
border: OutlineInputBorder(),
hintText: 'Treść',
fillColor: Color(0xffffffff),
filled: true,
prefixIcon: Container(
width: 20,
height: 100,
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Padding(
padding: const EdgeInsets.all(8.0),
child: Icon(Icons.topic_rounded),
),
Container(),
],
),
),
prefixIconConstraints: BoxConstraints(
minWidth: 35,
minHeight: 0,
),
),
validator: (value) {
if (value == null || value.isEmpty) {
return "error";
}
return null;
},
)
It will look like this
I am using TextFormField for my flutter application search field.
When i type a text bigger that the width of textformfield, then entered text it cropped to half an not visible completely.
Please find my below code and attached image for more understanding of problem.
TextFormField(
focusNode: focusNode,
controller: textController,
decoration: InputDecoration(
border: InputBorder.none,
icon: Icon(
Icons.search,
),
hintText: AppStrings.searchCatHint,
hintStyle: TextStyle(
fontSize: 17,),
),
autovalidate: true,
autocorrect: false,
autofocus: true,
);

Similar problem i have seen in another question also, but no solution provided.

Text display proper with #CarlosSR suggestion. But alignment issue as below.
I found a solution for the issue.
Problem description: On entering new text, old text should move to left without any problem.
Solution: I have specified a height for my TextFormField with Wrapping with Container. Code looks like below.
Container(
height:40,
child: TextFormFiled(...),
);
This worked for me. Thanks a lot for all your responses.
wrapping textformfield with container:
error will not occur:
Container(
color: Colors.black12,
width: 280,
height: 45,
child: TextFormField(
decoration: InputDecoration(
border: InputBorder.none,
icon: Icon(
Icons.search,
),
hintStyle: TextStyle(
fontSize: 17,),
),
autovalidate: true,
autocorrect: false,
autofocus: true,
),
),
error is with padding I guess if you are using:
Container(
color: Colors.black12,
width: 280,
height: 45,
child: Padding(
padding: const EdgeInsets.all(8.0),
child: TextFormField(
decoration: InputDecoration(
border: InputBorder.none,
icon: Icon(
Icons.search,
),
hintStyle: TextStyle(
fontSize: 17,),
),
autovalidate: true,
autocorrect: false,
autofocus: true,
),
),
),
This way you can only scroll the widget in horizontal axis, plus you add a padding to get your text in the position you want. In other, I recommend you to check for Align widget.
SingleChildScrollView(
scrollDirection: Axis.vertical,
child: Padding(
padding: const EdgeInsets.all(8.0),
child: TextFormField(
focusNode: focusNode,
controller: textController,
decoration: InputDecoration(
border: InputBorder.none,
icon: Icon(
Icons.search,
),
hintText: AppStrings.searchCatHint,
hintStyle: TextStyle(
fontSize: 17,),
),
autovalidate: true,
autocorrect: false,
autofocus: true,
),
),
),
I too happend to have the exact issue.The thing that i noticed that when i have a textfield in an container of some hardcoded height you might encounter this issue.Try removing the height of the container or just remove the textfields bottom padding.This will help.
The solution to this is using the CupertinoTextField widget. You can read about it here.
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 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,),
),
);
