Supporting info to reproduce

No response

Relevant log output

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':video_thumbnail'.
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
   > 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.

hi, so i recently upgraded flutter and android studio now it says gradle version not compatible

┌─ Flutter Fix ───────────────────────────────────────────────────────────────────────────────────┐
│ [!] Your project's Gradle version is incompatible with the Java version that Flutter is using │

│ │
│ If you recently upgraded Android Studio, consult the migration guide at │

│ │
│ Otherwise, to fix this issue, first, check the Java version used by Flutter by running flutter │ │ doctor --verbose. │
│ │
│ Then, update the Gradle version specified in │
│ D:\StudioProjects\chat_app\android\gradle\wrapper\gradle-wrapper.properties to be compatible │

@mellow0412 You can try using Android Studio Giraffe 2022.3.1 Patch 4 to resolve this issue.
Gradle 8.3
openjdk 17.0.12
Flutter 3.24.3

Since the video_thumbnail package is no longer actively maintained, could it be replaced with the get_thumbnail_video package or another actively managed alternative?

Since downgrading AGP might not be possible for everyone, another solution could be to use a fork like from this PR
