// This is a basic Flutter widget test.
//
// To perform an interaction with a widget in your test, use the WidgetTester
// utility that Flutter provides. For example, you can send tap and scroll
// gestures. You can also use WidgetTester to find child widgets in the widget
// tree, read text, and verify that the values of widget properties are correct.

void main() {
  testWidgets('Counter increments smoke test', (WidgetTester tester) async {
    // Build our app and trigger a frame.
    // await tester.pumpWidget(MyApp());
    //
    // // 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));
    // await tester.pump();

    // // Verify that our counter has incremented.
    // expect(find.text('0'), findsNothing);
