Your project is configured to compile against Android SDK 34, but the following plugin(s) require to be compiled against a higher Android SDK version:

- app_links compiles against Android SDK 35
- integration_test compiles against Android SDK 35
Fix this issue by compiling against the highest Android SDK version (they are backward compatible).
Add the following to /Users/radomir/StudioProjects/FirebaseUI-Flutter/tests/android/app/build.gradle:
