The flutter tools aren't launching when I press the button on Android Studio, and I also get a warning when I use flutter run.
I've tried flutter clean, but this still happens on both the terminal and Android Studio flutter plugin.

Does anyone have suggestions on how to fix this?
Rebooting my computer fixed it.

update_dyld_shared_cache is depreciate on macOS Monterey (my case 12.3.1). It makes flutter (2.10.4) cannot update. Let wait for new version of flutter to not request update.
I am using the flutter package flutter_background_service
https://pub.dev/packages/flutter_background_service/example
when the app is resuming, I have this infinite message

You can see this post and this issue.
But unfortunately it's not fixed yet. Maybe this is a bug.
When I want to start my project the following message appears
Launching lib\main.dart on Chrome in debug mode...
Then Google Chrome starts but it doesn't show anything except a white screen.
I have already reinstalled flutter, Dart SDK and VS Code.

I've recently updated Flutter to 1.25.0-8.1.pre in beta. I could run debug apk and build release. But, the release-apk doesn't work and it stuck on default splash screen. Where the problem lies in. Is there any such bug from Flutter?

I just downgrade the flutter version to 1.24.0-10.2.pre which released on 11/19/2020 and retried building release apk. And it worked fine. Actually the problem lies with Flutter new update on beta. The corresponding issue : https://github.com/flutter/flutter/issues/72705
