在flutter单元测试中找到Radio小部件

import 'package:flutter_test/flutter_test.dart';
import 'package:flutter/material.dart';

testWidgets('Find Radio Widget in Flutter Unit Test', (WidgetTester tester) async {
  // 这里可以编写测试代码
});

await tester.pumpWidget(
  MaterialApp(
    home: Scaffold(
      body: Radio(
        value: 1,
        groupValue: 1,
        onChanged: (value) {},
      ),
    ),
  ),
);

expect(find.byType(Radio), findsOneWidget);
