This is taking an unexpectedly long time

Question

When I am trying to add new dependency (packages) using flutter pub get in my flutter project i am getting This is taking an unexpectedly long time message. All other commends working fine like flutter run, flutter doctor etc. Only for flutter pub get i am facing this issue. That's why i am unable to add new dependency (packages) in my flutter app.

Result of flutter doctor -v

If you are working on Windows OS,

Close Android Studio
End process related to Flutter & Android Studio IDE from Task Manager.
Then, delete everything from Temp folder (run %temp% to open it directly).
Now, Open Android Studio and your Flutter project.
Run flutter pub get, it will work now.
