I create a new flutter project in android studio then "open project" the android part of it, I met an error in MainActivity.kt however it builds successfully.
My class pathes are:
and finally my dependencies are:
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.70"
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
I would be grateful if someone could help me.
Step 1 : open your project in AndroidStudio
Step 2 : open Terminal and goto your project path in terminal
Step 3 : Hit this command 'git clean -xfd'
Step 3 : Goto : File -> Invalidate caches/restart
You need to go to the flutter directory
rm -rf bin/cache/artifacts/engine/android*
Then go to project directory
flutter clean
flutter pub get
Also you can "Invalidate caches and restart" in Android Studio.
You need to enable the beta feature "Enable code completion, navigation, etc. for Java / Kotlin" at: Preferences -> Languages & Frameworks -> Flutter (bottom).
I had the same issue and was trying to debug for ages. The simple solution was to go to " File > Invalidate Caches/ Restart ".
As it seems it has some problems with androidx libraries! I backed from androidx and it works without error in kotlin and java both.
Downgrade from Android Studio's Kotlin plugin from 1.3.70 to 1.3.61 solved the problem for me
