Flutter - Warning (CocoaPods not installed Skipping pod install) Even While Installed

Question

I am trying to build a Flutter app with Geolocator plugin on Android Studio. When I am running the app I have the following warning - that prevents the app from running:

Warning: CocoaPods not installed. Skipping pod install. CocoaPods is used to retrieve the iOS and macOS platform side's plugin code that responds to your plugin usage on the Dart side. Without CocoaPods, plugins will not work on iOS or macOS. For more info, see https://flutter.dev/platform-plugins To install see https://guides.cocoapods.org/using/getting-started.html#installation for instructions.

Exception: CocoaPods not installed or not in valid state.

I tried every solution i found in the internet (Stackoverflow & GitHub) but nothing seems to work.

Important: When I tried to run the app from Xcode instead of from Android Studio, I had this error:

The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.

So what I did was - Change directory to ios (on the Flutter project) and running:

pod init
pod install

Tried to run again from Xcode and it worked perfectly. After it works on Xcode I tried to run it from Android Studio and the same error happens to me, preventing the app to launch.

Please help, I am spending hours on this error.

-- UPDATE --

I finally was able to run the app, all I did was to copy all the project files to a new project from scratch and it worked. Maybe it happened because of a certain conflict, since I imported someone else's project (from Angela Yu's Flutter Udemy course). Anyway, I still didn't find a fix for this fraustrating problem so if anyone recognizes something it would be great!

This error started appearing in mac os after the update

In my case, it is working to launch project in vs code, or running project with command flutter run

Android Canary last version solved problem

Update: As Ascot Harris mentioned, Android Studio Bumblebee | 2021.1.1 Patch 1 solves problem
