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),
  ],
)
