[Regression] Pose Detection 18 beta1 / beta2 errors when building due to uses-native-library

[fmardini]

Describe the bug
This happens when using ML Kit with Flutter. Creating a flutter plugin with version 18 beta1 works without any issues but using 18 beta2 is failing with

AAPT: error: unexpected element <uses-native-library> found in <manifest><application>.

To Reproduce
Example Steps to reproduce the behavior in sample app:

1. flutter create --org com.foo --template=plugin --platforms=android -a kotlin mlkit_pose
2. Add dependency on 18beta1 to android/build.gradle
3. cd example; flutter run -> ALL GOOD
4. Add dependency on 18beta2 to android/build.gradle -> BUILD FAILS

Expected behavior
Build to succeed

SDK Info:

• implementation 'com.google.mlkit:pose-detection-accurate:18.0.0-beta1' WORKS
• implementation 'com.google.mlkit:pose-detection-accurate:18.0.0-beta2' FAILS

The usage of was added in version 18.0.0-beta2 to deal with some Android 12+ requirements.

Could you try to see if upgrading your gradle version for Android build could fix it? See https://stackoverflow.com/questions/71615873/cannot-run-flutter-plugin-aapt-error-unexpected-element-uses-native-library

Thanks. I had initially tried that, but it didn't work. I tried again, but this time changing the build.gradle for both the plugin and the application got it to work. I'll create an issue on the flutter side so they update the project template.
