using the system back button from flutter driver

testing flutter integration-testing flutter-test flutterdriver

If you have adb installed on your machine, you can run a command to perform the backpress using a keyevent:

import 'dart:io';

await Process.run(  'adb',   <String>['shell', 'input', 'keyevent', 'KEYCODE_BACK'],   runInShell: true,);

Maybe this can help you

 await device.shellExec('input', <String>['keyevent', 'KEYCODE_BACK']);

Found in one of the official flutter driver tests link

Check out this link. In short, you'll need to use WillPopScope class that handles device back button with callbacks.
