Mockito doesn't work in integration test

[LucasXu0]

I added a @GenerateMocks([FilePicker]) under the integration_test path. But nothing generates after executing flutter pub run build_runner build.

But it works fine in the unit test. So, does mockito work in the integration tests?

Seems this was finally solved by Mockito 5.4.0 - just configure the build.yaml as https://stackoverflow.com/a/68275812 (and obviously upgrade Mockito to v5.4.0+)
