Flutter how to programmatically exit the app

Question

How can I programmatically close a Flutter application. I\'ve tried popping the only screen but that results in a black screen.

Answer 1

I prefer using

 Future.delayed(const Duration(milliseconds: 1000), () {
        SystemChannels.platform.invokeMethod('SystemNavigator.pop');
      });

Although, exit(0) also works but the app closes abruptly and doesn't look nice, kind of seems that the app has crashed.

 Future.delayed(const Duration(milliseconds: 1000), () {
       exit(0);
      });
