How to catch an error coming from a in flutter widget test?

Question

Here's a simple testwidget that reproduces the problem in a very simple way (thanks to Remi Rousselet for the simplification of the problem).

`void main() {
  testWidgets('MyApp Widget Test', ((WidgetTester tester) async {
    await tester.pumpWidget(MultiProvider(
      providers: [
        ChangeNotifierProvider(
          create: (_) => MovieViewModel(),
        ),
        ChangeNotifierProvider(
          create: (_) => PersonViewModel(),
        ),
      ],
      child: const MaterialApp(
        home: MovieScreen(),
      ),
    ));

    expect(find.text('Movie Screen'), findsOneWidget);
  }));
}`
