In the `examples/api`, the Android platform missed this step while migrating to the declarative plugins {} block described in [flutter-gradle-plugin-apply](https://docs.flutter.dev/release/breaking-changes/flutter-gradle-plugin-apply), so all examples of `examples/api` cannot run.
Fixes#147100
*If you had to change anything in the [flutter/tests] repo, include a link to the migration guide as per the [breaking change policy].*
