Ensure Example Packages Work on Android API 36 (#9241)
Ensured the example plugin apps on Android work on Android API 36 by updating configurations and sucessfully running flutter build apk (means the app can successfully build + all dependencies are resolvable). For compatibility with Android API 36, the example plugin apps on Android should have the following configurations:
targetSdk: 36
compileSdk: 36
AGP version: 8.9.1
Gradle version: 8.11.1
Most packages no longer require a manual bump of targetSdk and compileSdk due to usage of values from Flutter Gradle Plugin. Below is a list of example plugin apps on Android:
