      providers: [
        ChangeNotifierProvider.value(value: AuthProvider.initialize())
      ],
      child: MaterialApp(
          ebugShowCheckedModeBanner: false,

          theme: ThemeData(
            primarySwatch: Colors.red,
          ),

class ScreensController extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final auth = Provider.of<AuthProvider>(context);
    switch (auth.status) {
      case Status.Uninitialized:
        return Loading();
      case Status.Unauthenticated:

    await tester.pumpWidget(
        MyApp()); // ERROR LINE error: The function 'MyApp' isn't defined. (undefined_function at [food_app] testwidget_test.dart:15)

    // Verify that our counter starts at 0.
    expect(find.text('0'), findsOneWidget);
    expect(find.text('1'), findsNothing);

    // Tap the '+' icon and trigger a frame.
    await tester.tap(find.byIcon(Icons.add));
