textfield - How can I limit the size of a text field in flutter?

Question

The TextField widget doesn't seem to have a "limit" attribute to limit the number of characters that can be typed. How I can enforce that only a certain number of characters can be provided as input in a TextField Widget. I tried looking at the decoration property and potentially setting the limit there somehow but that didn't seem to work either. Is there a different widget I should be using?

Answer 1

Use inputFormatters property

example:

TextFormField(
      inputFormatters: [
        LengthLimitingTextInputFormatter(10),
      ]
    )

namespace

import 'package:flutter/services.dart';
