Hello @TomerconDevelopers
Try the above solution and if still the problem is there then please send the flutter doctor -v, flutter run -v, and minimal reproduction code
Thanks.

@TomerconDevelopers
If you were trying to hot restart or hot reload after adding google_maps plugin, then you first need to stop the app instance, run flutter pub get and then flutter run. You may also try flutter clean and then flutter run to see if it works.
If problem still persists, provide flutter doctor -v, pubspec.yaml and minimal code sample without any 3rd party plugins that shows the issue.
Thanks.

I fixed it by creating new project with latest flutter version, then moved code to new project.
