In my case this occurred after I updated the IntelliJ IDE. None of the above solutions worked, including opening in AS and rebuilding, invalidating caches, Flutter Clean, etc. The solution for me was to delete the android folder from the Flutter project and then re-add the Android platform as follows:

flutter create . --platforms=android

What solved my problem is by navigating to the android part of the application as mentioned earlier in the first answer where the indexing of the gradle files was performed and then when I re opened the project view of the application then the error was still not resolved. Then I run the following commands

  1. flutter clean

  2. flutter pub get

  3. flutter run

And then Invalidated the caches from the

  • Menu>> File >>Invalidated caches

and finally restarted the Android Studio and boom the error was solved there were no errors. These were the steps that resolved my error.

A little update on Servesh Dalvi's response: if you're using any of the latest versions of android studio like Android Studio Giraffe you might want to open your android part of your flutter project like the attached screenshot shows, by clicking on the android part directory, scroll down to Flutter, and select 'open Android module in Android Studio.Screenshot on opening android part of flutter project

I added flutter.jar as a library. This seemed to work.

I'm not sure if there are some unintended consequences yet!

Currently you are probably trying to directly edit the MainActivity class from your Flutter project. (By expanding android -> Navigation to 'MainActivity.java' or 'MainActivity.kt' and editing it).

I have observed that when we try to edit the native side code this way, Flutter is not able to recognize the android part.

What you can do is open the 'android' part of your flutter project and then edit it.

To achieve this :

  1. Click File -> Open -> Navigate to your current Flutter project -> Expand it and find the android part (refer the example below)

enter image description here

[1 = Your current Flutter project,2 = The android part of your flutter project]

  1. Click on that android part and click Open. Wait for the indexing and all to complete and then I dont think it will give those errors.

GLHF :)
