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.

Basically, rebuild the project or invalidate cache and restart. – kenn Feb 05 '21 at 06:14

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

Solved this issue by downgrading buld.gradle to com.android.tools.build:gradle:3.5.0
