FAILURE: Build completed with 3 failures.

1: Task failed with an exception.

- What went wrong: Execution failed for task ':image_gallery_saver:compileDebugKotlin'.
A failure occurred while executing org.jetbrains.kotlin.compilerRunner.GradleCompilerRunnerWithWorkers$GradleKotlinCompilerWorkAction
Compilation error. See log for more details

A problem occurred evaluating root project 'android'.
> A problem occurred configuring project ':app'.
   > Could not create an instance of type com.android.build.api.variant.impl.ApplicationVariantImpl.
      > Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

        If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

Execution failed for task ':app:processDebugMainManifest'.
> Incorrect package="com.example.test_app" found in source AndroidManifest.xml:   Setting the namespace via the package attribute in the source AndroidManifest.xml is no longer supported.
  Recommendation: remove package="com.example.test_app" from the source AndroidManifest.xml:

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:
- flutter_local_notifications compiles against Android SDK 35

Execution failed for task ':app:checkDebugAarMetadata'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction
   > 2 issues were found when checking AAR metadata:

       1.  Dependency ':flutter_local_notifications' requires core library desugaring to be enabled
           for :app.

           See https://developer.android.com/studio/write/java8-support.html for more
           details.

Could not determine the dependencies of task ':app:packageDebug'.
> Could not create task ':app:l8DexDesugarLibDebug'.
   > coreLibraryDesugaring configuration contains no dependencies. If you intend to enable core library desugaring, please add dependencies to coreLibraryDesugaring configuration.
