注意这个打包出来的 app-release.apk 在 电脑模拟器上 可能安装不上 报错 sdk 版本低或者 arm 虚拟机问题
$ flutter build apk
You are building a fat APK that includes binaries for android-arm, android-arm64 , android-x64.
If you are deploying the app to the Play Store, it's recommended to use app bund les or split the APK to reduce the APK size.
To generate an app bundle, run:
flutter build appbundle --target-platform android-arm,android-arm64,andr oid-x64
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,android-x6 4 --split-per-abi
Learn more on: https://developer.android.com/studio/build/configure-apk -splits#configure-abi-split
Removed unused resources: Binary resource data reduced from 484KB to 474KB: Remo ved 2%
