I have to make one application which take so many user input , that's why i use so many Textfiled in my code for taking user input.
An Textfiled validation time I simply use List of Global keys and it's work perfactly.
But problem is when user give wrong input then textfiled show an error message that time my Textbox UI can change (UI well change in very appropriately).
Pleas help , what can i do so my error message postion will be changed.
TextFiled code :
//this is inside the statfull Widget
GlobalKey<FormState> _formkeySubNumber = new GlobalKey();
Widget SubNumber_Input_Box() {
return Form(
//for form validation
key: _formkeySubNumber,
child: Container(
margin: EdgeInsets.only(top: 7, left: 6),
height: 38,
width: 300,
decoration: BoxDecoration(
color: HexColor("#D9D9D9"),
borderRadius: BorderRadius.all(Radius.circular(10)),
),
//padding
child: Padding(
padding: EdgeInsets.only(left: 12),
//textfiled
child: TextFormField(
//for validation
validator: (value) {
if (value == null || value.isEmpty) {
return 'Please Enter Subject Number';
}
return null;
},
//for storing user input && value in string format so we convert into the int formate
onChanged: (value) {
subjectNumber = int.tryParse(value)!;
},
//for only number
keyboardType: TextInputType.number,
decoration: const InputDecoration(
hintText: "Enter Minimum-4 to Maximum-8 Subject",
hintStyle: TextStyle(
fontFamily: "RobotoSlab",
fontSize: 14,
),
//for remove underline from input filed
border: InputBorder.none,
),
//for store only integer value
inputFormatters: <TextInputFormatter>[
FilteringTextInputFormatter.allow(RegExp(r'[0-9]')),
],
),
),
),
);
}
And this call inside the one Button Like that
[Container(
margin: EdgeInsets.only(top: 5),
child: ElevatedButton(
child: Text("Go"),
style: ElevatedButton.styleFrom(
primary: HexColor("#EE6C4D"),
//this colour set (opacity is low) when button is disable
onSurface: HexColor("#E0FBFC"),
),
//store user value -->subjectNumber
onPressed: isGoButtonActive
? () {
//for Form Validation
if (_formkeySubNumber.currentState!
.validate()) {
//this show the container after prerssed button
showContainer1();
}
setState(() {
// //this is for store subjectnumber value from user input
// subjectNumber =
// subNumber_Controller.text;
// print("Subject Number Is : $subjectNumber");
});
}
: null,
),
),]
You have created a container around the textfield with specific height. For styling a textfield you can use
TextField(
decoration: InputDecoration(
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(10.0),
),
filled: true,
hintStyle: TextStyle(color: Colors.grey),
hintText: "Type in your text",
fillColor: Colors.white),
)
This way the error message appears below the textfield and outside the white area.
You can remove the height from Form> Container. And it will give you flexible height based on error state.
Widget SubNumber_Input_Box() {
return Form(
key: _formkeySubNumber,
child: Container(
width: 300,
color: HexColor("#D9D9D9"),
//padding
child: Padding(
padding: EdgeInsets.only(left: 12),
child: TextFormField(
autovalidateMode: AutovalidateMode.onUserInteraction, // you might like this as well
Also I will suggest to look at OutlineInputBorder
Widget SubNumber_Input_Box() {
return Form(
key: _formkeySubNumber,
child: Padding(
padding: EdgeInsets.only(left: 12),
child: TextFormField(
autovalidateMode: AutovalidateMode.onUserInteraction,
//for validation
validator: (value) {
if (value == null || value.isEmpty) {
return 'Please Enter Subject Number';
}
return null;
},
//for storing user input && value in string format so we convert into the int formate
onChanged: (value) {
subjectNumber = int.tryParse(value)!;
},
//for only number
keyboardType: TextInputType.number,
decoration: const InputDecoration(
hintText: "Enter Minimum-4 to Maximum-8 Subject",
hintStyle: TextStyle(
fontFamily: "RobotoSlab",
fontSize: 14,
),
enabledBorder: OutlineInputBorder(),
errorBorder: OutlineInputBorder(),
focusedBorder: OutlineInputBorder(),
border: OutlineInputBorder(),
),
//for store only integer value
inputFormatters: <TextInputFormatter>[
FilteringTextInputFormatter.allow(RegExp(r'[0-9]')),
],
),
),
);
}
I want to remove the 0/10 mark below the telephone field (see screenshot)
My code:
Container(
width: 334,
height: 70,
child: Padding(
padding: const EdgeInsets.only(left: 1, right: 30),
child: IntlPhoneField(
decoration: InputDecoration(
labelText: 'Phone Number',
border: OutlineInputBorder(
borderSide: BorderSide(),
),
),
initialCountryCode: 'IN',
onChanged: (phone) {
print(phone.completeNumber);
},
),
),
),
Assuming you're using a normal Flutter TextFormField or equivalent,
counterText: '',
Assuming you have used the TextFormField widget. You can hide counter text by making it an empty value.
Example code:
TextFormField(
decoration: const InputDecoration(
counterText: '',
),
);
It seems you are using intl_phone_field package. The (not so good) documentation contains a disableLengthCheck property. If you set that to true the 0/10 is gone. like this:
IntlPhoneField(
disableLengthCheck: true,
decoration: const InputDecoration(
labelText: 'Phone Number',
border: OutlineInputBorder(
borderSide: BorderSide(),
),
),
initialCountryCode: 'IN',
onChanged: (phone) {
print(phone.completeNumber);
},
),
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,),
),
);
