)

Assert that a widget matching finder is visible in the widget tree.

Example:

expectVisible(find.byType(FloatingActionButton));
expectVisible(find.byIcon(Icons.notifications));
expectVisible(find.byKey(Key('submit_btn')));

void expectVisible(Finder finder) {
  expect(
    finder,
    findsOneWidget,
    reason: 'Expected widget to be visible: $finder',
  );
}
