How to close/kill app on Flutter

Question

I am actually aware of this implementation: Flutter programmatically closing the app, but when the app closes is still in background. How can I absolutely kill the app and not let it be in background?

Thank you!

Answer 1

If you don't want to use invokeMethod, you can directly close the app using

SystemNavigator.pop(); // Only works on Android.

While exit(0) works on both iOS and Android, it shouldn't be used on either. Read this answer for more information.

Answer 2

You can use exit(0). But app exits abruptly. You can use the below code which is much smoother.

SystemChannels.platform.invokeMethod<void>('SystemNavigator.pop')
