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

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.

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.

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!

you can use InputDecoratoin to hide letter counter.

TextFormField(
   decoration: InputDecoration(
     labelText: "username",
     counterStyle: TextStyle(height: double.minPositive,),
     counterText: ""
)

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

Simply set counter to Offstage() will do the trick.

TextField(
    maxLines: 1,
    decoration: InputDecoration(
      counter: Offstage(),
    ),
),
