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?

Answer 1

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:

1. await driver.tap(find.text('11'));
   

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

3. await driver.tap(find.text('OK'));
   

What these steps will do is:

1. Tap on button which has a text of "11",
2. Wait for 1 second, and then
3. Tap on the "OK" button.
