Release apk won't run

I'm building release APK with flutter run --release but I'm getting this exception

Failed to register native method io.flutter.view.FlutterNativeView.nativeRunBundleAndSource(JLjava/lang/String;Ljava/lang/String;Ljava/lang/String;)V in /data/app/com.example.myapp-1/base.apk

However, debug variant runs normally so if I run the app just with flutter run everything is fine.

By the way, I'm executing flutter clean before avery build.

What is the cause of this?

Found the solution on my own, but I'm posting this answer for people who are having the same problem.

Turns out that build.gradle was causing exception

shrinkResources true // for this to work minifyEnabled must be set to true
minifyEnabled true // if set to true apk will not build

Solved it by using only proGuard so snippet below is working buildTypes section of app-level build.gradle

buildTypes {
  release {
    debuggable false
    useProguard true
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    signingConfig signingConfigs.release
  }
}
