Flutter functioning incorrectly on android studio

Question

I am currntly getting this error on my android when I attempt anything regarding a pub upgrade. the error is as follows:

Building flutter tool... Running pub upgrade... Error on line 1, column 1 of pubspec.lock: Unexpected character. ╷ 1 │ │ ^ ╵ Error (65): Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (9 tries left)

I have deleted my pubspec.lock as suggested in other articles but that did not work for me and I cannot run the app or make any flutter related commands in my terminal. flutter doctor is not working either giving and out the same error

Answer 1

It is difficult to be sure about the problem you are having, but I recommend you try to delete the pubspec.lock inside your flutter installation directory and then run a flutter pub upgrade

your_flutter_directory/packages/flutter_tools/pubspec.lock
