$ flutter build apk

FAILURE: Build failed with an exception.

* Where:
Build file '/path/to/my_app/android/app/build.gradle.kts' line: 1

* What went wrong:
An exception occurred applying plugin request [id: 'dev.flutter.flutter-gradle-plugin']
> Failed to apply plugin 'dev.flutter.flutter-gradle-plugin'.
   > Error: Your project's Android Gradle Plugin version (9.3.1) is not yet supported. Flutter does not support Android Gradle Plugin 9, and support will be added in a future Flutter release. Please downgrade your Android Gradle Plugin version to a version below 9.0.0 to continue.
     Alternatively, use the flag "--android-skip-build-dependency-validation" to bypass this check (unsupported; your build may fail).

     Potential fix: Your project's AGP version is typically defined in the plugins block of the `settings.gradle` file (/path/to/my_app/android/settings.gradle), by a plugin with the id of com.android.application. 
     If you don't see a plugins block, your project was likely created with an older template version. In this case it is most likely defined in the top-level build.gradle file (/path/to/my_app/android/build.gradle) by the following line in the dependencies block of the buildscript: "classpath 'com.android.tools.build:gradle:<version>'".
