Change app name in pubspec.yaml cause error on imports

Question

I have created a new flutter project in AS and for some reason the name in pubspec.yaml for my app is just app even when I named it something else when I created new app

name: app
description: My new application.

When I rename it to whatever I need then all my imports error out in my project.

Example:

import 'package:app/main.dart';

So how do you change the name in pubspec.yaml without crashing all imports

UPDATE After renaming name, AS doesn't show package option with the new name

Answer 1

For example, if the default app name is

name: defaultappname
description: My new application.

and you want to change it to

name: app
description: My new application.

then you have to just do the search and replace operation:
