How can I hide letter counter from bottom of TextField in Flutter - dart

Question

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.

Answer 1

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.

Answer 2

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!

Answer 3

you can use InputDecoratoin to hide letter counter.
TextFormField(
decoration: InputDecoration(
labelText: "username",
counterStyle: TextStyle(height: double.minPositive,),
counterText: ""
)

Answer 4

You can hide the counter by adding counterText: '', inside the textfield decoration. It will simply display an empty String.

Answer 5

Simply set counter to Offstage() will do the trick.
TextField(
maxLines: 1,
decoration: InputDecoration(
counter: Offstage(),
),
),

Answer 6

You can do:
TextField(
maxLength: 10,
buildCounter: (BuildContext context, { int currentLength, int maxLength, bool isFocused }) => null,
)

Answer 7

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,
),

Answer 8

Add counterText: "", to InputDecoration
TextField(
decoration: InputDecoration(
counterText: "",
),
maxLength: 10,
),

Answer 9

Whenever you don't need something in flutter just put an empty container!
TextField(
decoration: InputDecoration(
hintText: "Email",
counter: Container(),
),
maxLength: 20,
),

Answer 10

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,
);

Answer 11

This alone solved my problem!
TextField(
decoration: InputDecoration(
labelText: "Table Number",
counterText: ""
)

Answer 12

For null-safety use this:
TextField(
maxLength: 10,
buildCounter: (BuildContext context, {int? currentLength, int? maxLength, bool? isFocused}) => null,
)

Answer 13

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;
},
),

Answer 14

you can use InputDecoratoin to hide the letter counter.
TextField(
keyboardType: TextInputType.number,
maxLength: 10,
decoration: InputDecoration(
**counterText:""**)
)

Answer 15

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,
)),
...
)

Answer 16

You can follow the below codes.
TextField(
controller: myController,
maxLength: 3,
buildCounter: (BuildContext context, {int currentLength, int maxLength, bool isFocused}) =>null
)

Answer 17

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()

Answer 18

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.

Answer 19

Not pretty but works by removing the counter:
TextFormField(
buildCounter: (
BuildContext context, {
required int currentLength,
int? maxLength,
required bool isFocused,
}) => null,

Answer 20

Use a SizedBox.shrink() for the counter widget in InputDecoration:

Answer 21

Use a SizedBox with zero height and width:
TextField(
maxLength: 400,
decoration: InputDecoration(
counter: SizedBox(
width: 0,
height: 0,
),),)

Answer 22

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(),
),
)
)
