How can I hide letter counter from bottom of TextField in Flutter
DartFlutterDart Problem Overview
I'm facing a small problem. As you can see, i have set maxLength 1 of TextField in Flutter, But i'm unable to hide bottom label of text counter.
Dart Solutions
Solution 1 - Dart
To hide counter value from TextField or TextFormField widget while using maxLength attribute, try following:
TextField(
decoration: InputDecoration(
hintText: "Email",
counterText: "",
),
maxLength: 40,
),
In this, I have set counterText attribute inside InputDecoration property with empty value. Hope it will help.
Solution 2 - Dart
This is the proper approach, it will prevent extra space below the Text Field, and also avoid extra code to set a null widget.
You can use input formatters in TextField
The following is:
inputFormatters:[
LengthLimitingTextInputFormatter(1),
]
Thank You!
Solution 3 - Dart
you can use InputDecoratoin to hide letter counter.
TextFormField(
decoration: InputDecoration(
labelText: "username",
counterStyle: TextStyle(height: double.minPositive,),
counterText: ""
)
Solution 4 - Dart
You can hide the counter by adding counterText: '', inside the textfield decoration. It will simply display an empty String.
Solution 5 - Dart
Simply set counter to Offstage() will do the trick.
TextField(
maxLines: 1,
decoration: InputDecoration(
counter: Offstage(),
),
),
Solution 6 - Dart
You can do:
TextField(
maxLength: 10,
buildCounter: (BuildContext context, { int currentLength, int maxLength, bool isFocused }) => null,
)
Solution 7 - Dart
Most of the answers seem to work. Another way would be to assign the counter with a shrink SizeBox.
TextField(decoration: InputDecoration(
hintText: "Email",
counter: SizedBox.shrink()
),
maxLength: 40,
),
Solution 8 - Dart
Whenever you don't need something in flutter just put an empty container!
TextField(
decoration: InputDecoration(
hintText: "Email",
counter: Container(),
),
maxLength: 20,
),
Solution 9 - Dart
Simply set buildCounter to null.
It is a callback that generates a custom [InputDecorator.counter] widget
TextField(
maxLength: (some length),
buildCounter: (BuildContext context, {int currentLength, int maxLength, bool isFocused}) => null,
);
Solution 10 - Dart
Add counterText: "", to InputDecoration
TextField(
decoration: InputDecoration(
counterText: "",
),
maxLength: 10,
),
Solution 11 - Dart
You can use input formatters in TextField setting a limit to input and this is the best approach if you just want to hide the counter making a input limit.
import 'package:flutter/services.dart';
inputFormatters:[
LengthLimitingTextInputFormatter(1),
]
Or you can customize the decoration making a counter = Container():
decoration: InputDecoration(
hintText: "Email",
counter: Container(),
),
You if prefer to customize the buildCounter, here is how to do it properly (you can also customise the font, color etc). When you text field loses the focus the counter limits will disappears. Or you can just set
TextField(
controller: _clienteTextEditingController,
maxLength: 50,
buildCounter: (BuildContext context,
{int currentLength, int maxLength, bool isFocused}) {
return isFocused
? Text(
'The Input Limits are: $currentLength/$maxLength ',
style: new TextStyle(
fontSize: 10.0,
),
semanticsLabel: 'Input constraints',
)
: null;
},
),
Solution 12 - Dart
you can use InputDecoratoin to hide the letter counter.
TextField(
keyboardType: TextInputType.number,
maxLength: 10,
decoration: InputDecoration(
**counterText:""**)
)
Solution 13 - Dart
This alone solved my problem!
TextField( decoration: InputDecoration( labelText: "Table Number", counterText: "" )
Solution 14 - Dart
Another solution is to hide the counter widget by using SizedBox:
TextFormField(
...
decoration: InputDecoration(
contentPadding: EdgeInsets.all(10.0),
counter: new SizedBox(
height: 0.0,
)),
...
)
Solution 15 - Dart
You can follow the below codes.
TextField(
controller: myController,
maxLength: 3,
buildCounter: (BuildContext context, {int currentLength, int maxLength, bool isFocused}) =>null
)
Solution 16 - Dart
Container(
height: 48,
alignment: Alignment.centerLeft,
padding: EdgeInsets.symmetric(horizontal: 16),
decoration: BoxDecoration(
border: Border.all(
color: CustomColors.kToDark,
),
color: CustomColors.White,
borderRadius: BorderRadius.all(Radius.circular(8))),
child: TextFormField(
textAlign: TextAlign.left,
cursorColor: CustomColors.kToDark,
maxLength: 30,
controller: _titleController,
keyboardType: TextInputType.text,
decoration: InputDecoration(
counterText: "",
border: InputBorder.none,
isDense: true,
contentPadding: EdgeInsets.all(0))),
),
Use counterText: "" inside InputDecoration()
Solution 17 - Dart
In case you are still looking for the answer in 2020 here goes:
decoration: InputDecoration(
counter: Spacer(),
labelText: "National ID #",
border: InputBorder.none,
hintText: 'e.g 01-1234567A12',
hintStyle: TextStyle(color: Colors.grey)),
In the TextField, use a Spacer() as counter... hope this helps, i dont know if it breaks anything else but mine works fine.
Solution 18 - Dart
Not pretty but works by removing the counter:
TextFormField(
buildCounter: (
BuildContext context, {
required int currentLength,
int? maxLength,
required bool isFocused,
}) => null,
Solution 19 - Dart
For null-safety use this:
TextField(
maxLength: 10,
buildCounter: (BuildContext context, {int? currentLength, int? maxLength, bool? isFocused}) => null,
)
Solution 20 - Dart
Use a SizedBox with zero height and width:
TextField(
maxLength: 400,
decoration: InputDecoration(
counter: SizedBox(
width: 0,
height: 0,
),),)
Solution 21 - Dart
As mentioned by @user10481267 in the best answer would be use buildCounter property. This gives extreme flexibility and you can even decide dynamically to show the counter or not.
I was building a dynamic form with the required properties in JSON. My implementation is as follows:
TextFormField(
buildCounter: (BuildContext context,
{
int currentLength,
int maxLength,
bool isFocused}) {
if (isFocused)
return formFields[index]["max"] == null
? null
: Text(
'$currentLength / $maxLength',
semanticsLabel: 'character count',
);
else
return null;
},
maxLength: formFields[index]["max"] ?? 100,
decoration: new InputDecoration(
labelText: formFields[index]["hint"] ?? "",
fillColor: Colors.green,
border: new OutlineInputBorder(
borderRadius: new BorderRadius.circular(15.0),
borderSide: new BorderSide(),
),
)
)
