flutter build apk --release

You are building a fat APK that includes binaries for android-arm, android-arm64.

If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size. To generate an app bundle, run: flutter build appbundle --target-platform android-arm,android-arm64 Learn more on: https://developer.android.com/guide/app-bundle To split the APKs per ABI, run: flutter build apk --target-platform android-arm,android-arm64 --split-per-abi Learn more on: https://developer.android.com/studio/build/configure-apk-splits#configure-abi-split Initializing gradle...

Over time, android has spread throughout the world and runs on more than 2 billion devices. Because of android running on multiple platforms and foam-factors, it is very important to make sure an optimised app is installed on each platform.

For eg., a phone which doesn't have a high-resolution screen, should not get high-res images and thus reduce the size of the APK.

To make sure your app is optimized for each platform, android provides 2 methods:

  1. You can split your app into multiple APKs optimized for each platform.

    flutter build apk --split-per-abi

  2. Create an app-bundle and deploy it to play store, this way when a user downloads your app, play store automatically extracts and provides the APK which is optimized for that device.

    flutter build appbundle --target-platform android-arm,android-arm64
