Xcode – Flutter build iOS error CocoaPods not installed. Skipping pod install

Iam using Mac and upgraded to Android studio "Bumblebee", only in Mac when I try to do: Build -> Flutter -> Build iOS it shows this warning:

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. CocoaPods not installed or not in valid state. Process finished with exit code 1

But I did already this
gem install cocoapods Successfully installed cocoapods-1.11.2 Parsing documentation for cocoapods-1.11.2 Done installing documentation for cocoapods after 1 seconds 1 gem installed

When I do sudo gem install cocoapods I got:
ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /usr/bin directory.

I did Invalidate Caches and pod install also, but it still shows same warning.
