I used some packages that I no longer need in my flutter project, namely the wilddog_auth and wilddog_sync, I can remove the imports from pubspec.yaml file, and my dart files (aka removing import 'package:wilddog_sync/wilddog_sync.dart' etc.) and remove imports in MainActivity.java as well as in Xcode project but I can't purge the unused files installed by flutter, cocoapod and gradle. Now is there a unified command in flutter where I can remove all unused packages at once?
I am pretty sure using flutter clean only removes build folder and using flutter packages get after removing packages from pubspec.yaml doesn't remove packages from cocoapod or gradle either.
For example, after flutter clean and flutter packages get I rebuilt the project:

Yet all the package files remained.
Of course I could go into ./ios/ to run pods install to remove pods:

If you are running Windows as your OS, you can find the packages under the folder that you installed your Flutter SDK to when setting up Android Studio. In my case - using Windows 10 - the path is as follows, where C:\ is my primary harddrive and flutter\ the folder containing the Flutter SDK...
From the terminal: Run flutter pub get . From Android Studio/IntelliJ: Click Packages get in the action ribbon at the top of pubspec. yaml . From VS Code: Click Get Packages located in right side of the action ribbon at the top of pubspec.
You are welcome, Yes you are right; that's why you may need to keep a backup from your original pubspec. lock before you delete it if it isn't tracked by a source code version control :D I will add it as a note in the answer.
delete the hosted folder of .pub-cache in flutter SDK directory
cd path/to/flutter_sdk_directory
rm -rf .pub-cache/hosted
delete the .packages file in the project root directory
cd path/to/project_root_directory
rm -rf .packages
get packages for the project
cd path/to/project_root_directory
flutter pub get
open the project in Android Studio
done.
