无法在 flutter 中构建 apk

Question

I am running flutter build apk --obfuscate --split-debug-info=./build/info to build android apk

How can I fix the following error?

Running "flutter pub get" in myapp...
1.0s 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 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,android-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-x64 --split-per-abi Learn more on: https://developer.android.com/studio/build/configure-apk-splits#configure-abi-split Plugin project:location_web not found. Please update settings.gradle.

Try this modification in your build.gradle (app level)

lintOptions {
            //Code...
            checkReleaseBuilds false
            //Added the above line so that 'flutter build apk' could work
        }
