flutter integration test how to tap on camera button

Question

In flutter integration test, if we want to tap on a button that is built by ourselves, we can easily do it by:

await driver.tap(find.byValueKey("my_lovely_button_key"));

However, if a widget is not built by us, for example, a date picker, an image picker, etc., how do we tap on any of the buttons there?

Tried [Find a specific widget instance](https://flutter.dev/docs/cookbook/testing/widget/finders#3-find-a-specific-widget-instance) from the flutter docs? — dev-aentgs, Jun 20 '20 at 15:58
Right, in cases like custom Button or similar we wont have details about the widget. — dev-aentgs, Jun 20 '20 at 16:11
Perhaps you don't have to open a camera at all in your tests. It can be skipped and have `image_picker` lib return you some image immediately after opening camera following this answer to this question: https://stackoverflow.com/questions/56588555/how-to-test-imagepicker-in-flutter-driver — crollywood, Jun 20 '20 at 17:20

Regarding the date picker, what I found to be useful is that you can click on any button using:

await driver.tap(find.text('btn_name'));

For example, if you need the date 11 June 2020, you need to do these steps:

await Future.delayed(const Duration(seconds: 1));

What these steps will do is:
