How can we display the count of input characters entered by the user and how many characters user can type in that TEXTFORMFIELD in Flutter? Like this

Solution

You can add maxLength property (it will show the writtenCharacters/totalLimit)

TextFormField(
  maxLength: 45,
)

Or you can also have alternative (it will not show the writtenCharacters/totalLimit), but for this you need to import

import 'package:flutter/services.dart';

TextFormField(
  inputFormatters: [
    LengthLimitingTextInputFormatter(45),
  ],
)
