Question

I am getting the following when trying to build release apk This is the following errors

Execution failed for task ':shared_preferences:verifyReleaseResources'. A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade

FAILURE: Build failed with an exception.

• What went wrong: A problem occurred configuring root project 'android_intent'.

  SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

      flutter build apk --release
  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
