Heads up... You've reached locked video content where the transcript will be shown as obfuscated text.

The FilterPage consists of a series of tech domains that the user might be most interested in. You’ll let the user either show all the domains, or just filter down to one particular domain. To help with creating the FilterPage and keep its code nice and tidy, in this episode you’ll create a FilterWidget that displays a filter value. The FilterPage will then consist of a set of these filter widgets.

class FilterWidget extends StatelessWidget {
}
import 'package:flutter/material.dart';
final int value;
final int groupValue;
final ValueChanged<int?> onChanged;
final String text;
  const FilterWidget(
      {Key? key,
      required this.value,
      required this.groupValue,
      required this.onChanged,
      required this.text})
      : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Row(
      children: [
        Radio(
          value: value,
          groupValue: groupValue,
          onChanged: onChanged,
        ),
        Text(
          text,
          style: const TextStyle(fontSize: 16.0),
        ),
      ],
    );
  }
