[Question] Release apk file size doubled with update

[Priyantha-Kingslake]

I noticed a significant change in my app’s release APK size after upgrading Flutter.

• Previously, the release APK was around 25 MB, while the debug APK was ~50 MB.
• After upgrading to Flutter 3.35.5, the release APK is now 57.5 MB.
• When I downgraded to Flutter 3.32.8, the release APK size went back down to 26.6 MB (Only minor breaking changes which were related to radio groups).
• I tried again in Flutter 3.35.1 and size went back upto ~50MB.

Is this increase in APK file size between Flutter 3.32.8 and 3.35.1 expected?

I tested with flutter default counter app

flutter create test --platforms=android
cd test
flutter pub get
flutter build apk --release

Following is what I've found

• Flutter 3.32.8 - 18.3MB
• Flutter 3.35.1 - 39.4MB
• Flutter 3.35.5 - 39.4MB
