flutter - build apk does't work, but debug apk works as expected

Question

My build apk doesn't work as expected. but debug apk works perfectly. when i run flutter run --release -v it shows:-

• MissingPluginException(No implementation found for method getDatabasesPath on channel com.tekartik.sqflite)

• Unhandled Exception: MissingPluginException(No implementation found for method pickImage on channel plugins.flutter.io/image_picker)

How can i solve this issue.

This probably related with current issue in flutter (https://github.com/flutter/flutter/issues/65334) where DefaultLifecycleObserver got removed by proguard. See explanation: https://github.com/flutter/flutter/issues/58479#issuecomment-763259817

The solution is by adding the line below to your android app/proguard-rules.pro:

-keep class androidx.lifecycle.DefaultLifecycleObserver
