You are applying Flutter's main Gradle plugin imperatively using the apply script method, which is deprecated and will be removed in a future release. Migrate to applying Gradle plugins with the declarative plugins block: https://flutter.dev/go/flutter-gradle-plugin-apply

FAILURE: Build failed with an exception.

• What went wrong:
  Some problems were found with the configuration of task ':app:compileDebugRenderscript' (type 'RenderscriptCompile').

  • In plugin 'com.android.build.gradle.api.AndroidBasePlugin' type 'com.android.build.gradle.tasks.RenderscriptCompile' method 'useAndroidX()' should not be annotated with: @input.

    Reason: Input/Output annotations are ignored if they are placed on something else than a getter.

    Possible solutions:

    1. Remove the annotations.
    2. Rename the method.

    Please refer to https://docs.gradle.org/7.6.1/userguide/validation_problems.html#ignored_annotations_on_method for more details about this problem.

  • In plugin 'com.android.build.gradle.api.AndroidBasePlugin' type 'com.android.build.gradle.tasks.RenderscriptCompile' property 'ndkConfig' is missing an input or output annotation.

    Reason: A property without annotation isn't considered during up-to-date checking.

    Possible solutions:

    1. Add an input or output annotation.
    2. Mark it as @internal.

    Please refer to https://docs.gradle.org/7.6.1/userguide/validation_problems.html#missing_annotation for more details about this problem.

Run with --stacktrace option to get the stack trace.
Run with --info or --debug option to get more log output.
Run with --scan to get full insights.
