无法在我的Flutter 应用程序中使用GoRouter测试导航

Scenario个

我是小部件测试和GoRouter的新手.我有一个非常简单的测试用例:

• 有两个屏幕- LoginPage作为第一个屏幕加载，和CheckoutPage
• LoginPage有一个按钮.一旦我点击它，我就会被带到CheckoutPage号公路.

我正在使用GoRouter进行导航.

Code个

以下是main.dart年度MaterialApp的设置方式:

MaterialApp.router(
            debugShowCheckedModeBanner: false,
            routerConfig: GoRouteInformation.router,
            title: "Neon Student",
          ),

以下是routerConfig个和RouteNames个班级:

100

class GoRouteInformation {
  static final GoRouter router = GoRouter(
    routes: [
      GoRoute(
        path: '/',
        name: RouteNames.login,
        builder: (context, state) => const LoginPage(),
        routes: [
          GoRoute(
            path: 'checkout',
            name: RouteNames.checkout,
            builder: (context, state) => const CheckoutPage(),
          ),
        ],
      ),
    ],
  );
}

100

class RouteNames {
  static const String login = 'login';
  static const String checkout = 'checkout';
}

以下是loginpage_test.dart中的代码:

testWidgets('Navigates from LoginPage to CheckoutPage', (WidgetTester tester) async {
    await tester.pumpWidget(const MainApp());
    await tester.pumpWidget(const MaterialApp(home: LoginPage()));

    expect(find.byType(LoginSection), findsOneWidget);
    expect(find.byType(SplitDivider), findsOneWidget);

    Finder subscribeButton = find.byKey(const ValueKey('Subscribe'));
    expect(subscribeButton, findsOneWidget);

    await tester.tap(subscribeButton);
    await tester.pumpAndSettle();

    expect(find.byType(CheckoutPage), findsOneWidget);
  });

EDIT:这是我的main.dart

void main() {
  runApp(const MainApp());
}

class MainApp extends StatelessWidget {
  const MainApp({super.key});

  @override
  Widget build(BuildContext context) {
    return ScreenUtilInit(
      designSize: const Size(428, 926),
      minTextAdapt: true,
      splitScreenMode: true,
      builder: (_, child) {
        return GestureDetector(
          onTap: () {
            FocusManager.instance.primaryFocus?.unfocus();
          },
          behavior: HitTestBehavior.opaque,
          child: MaterialApp.router(
            debugShowCheckedModeBanner: false,
            routerConfig: GoRouteInformation.router,
            title: "Neon Student",
          ),
        );
      },
    );
  }
}

Problem个

当我运行flutter test时，我得到以下错误:

1. The following assertion was thrown while handling a gesture: No GoRouter found in context 'package:go_router/src/router.dart': Failed assertion: line 507 pos 12: 'inherited != null'个
2. The following TestFailure was thrown running a test: Expected: exactly one matching candidate Actual: _TypeWidgetFinder:<Found 0 widgets with type "CheckoutPage": []> Which: means none were found but one was expected个

Request个

我想知道我的小部件测试代码中有什么错误导致测试失败，以及如何纠正它.
