[Bug] Native .so files (e.g., libface_detector_v2.jni.so) not aligned for 16 KB page size (Android 15+)

[flutter-developer-105]

Describe your issue. If applicable, add screenshots to help explain your problem.

The google_mlkit_face_detection package (v0.13.1) bundles native ML Kit libraries that are not aligned to 16 KB page sizes, causing APK Analyzer warnings and potential Play Store rejections after November 1, 2025. This affects Android 15+ (API 35+) apps.

Please update in the next release.

Steps to reproduce.

1. Add google_mlkit_face_detection: ^0.13.1 to pubspec.yaml.
2. Run flutter build apk --release.
3. Analyze the APK (Build > Analyze APK) - .so files like libface_detector_v2.jni.so show "No" with "16 KB zip/64 KB LOAD section".

What is the expected result?

Native libraries should be rebuilt with NDK r28+ and -Wl,-z,max-page-size=16384 in linker flags.

Hi Guys

After resolving the Android SDK 35 support issue, the warning about the 16KB memory alignment disappeared.

I'm not sure whether this was resolved by upgrading the Flutter version or due to some other reason. If you still have the Android SDK 35 support issue, I recommend addressing that first.

I experienced the same problem as you all, but after resolving the Android SDK 35 issue, this warning disappeared.
