How to interact with native UI elements from flutter integration_test?

Question

I am trying to do an automated testing of the user flow in a flutter app. For this I am using flutter integration test package (https://flutter.dev/docs/testing/integration-tests). I have written tests using integration_test package. Though these tests run on a physical device, there are situation where I have to interact with native UI elements (for example, clicking on a permission button to give permission to camera etc.) However, I am not able to interact with the native UI elements specifically :

1.Tapping Allow on System permission dialog
2.Tapping on Capture button when camera is opened
3.Selecting an image from gallery

I would like to understand how the above situations can be achieved through a script and hence automated. Also, can frameworks like appium-flutter-driver or flutter-driver be used in conjunction with flutter_integration to achieve this. Any pointers would be helpful.

Solution

Long story short, it is likely not currently possible.

These two GitHub issues are pretty much our concern:

• Add support to test native permission dialog (#87440)
• Allow driving native UI interactions from Dart (#86295)

But, so far, every comment about the matter has been a remark about how difficult it is. The only "solution" from the Android side is to use Android ADB—but, at that point, it isn't even an integration_test anymore.
