How to keep application awake in flutter?

How to keep an application from locking the screen in flutter?

Is there a flag to turn it off an on? Does flutter SDK expose this?

Something like keepAwake(true);

Thank you

As support for the screen plugin that @Tree mentioned has been discontinued and there are some issues with it now, you can use wakelock.
Full disclosure: I am the author of this plugin, however, it is basically a port of the wakelock functionality from the screen plugin, with the issues fixed:

import 'package:wakelock/wakelock.dart';

// To keep the screen on:
Wakelock.enable(); // or Wakelock.toggle(on: true);

// To let the screen turn off again:
Wakelock.disable(); // or Wakelock.toggle(on: false);

I found plugin that does the job. https://pub.dartlang.org/packages/screen

import 'package:screen/screen.dart';

// Prevent screen from going into sleep mode:
Screen.keepOn(true);

You also need to set permission for android

<uses-permission android:name="android.permission.WAKE_LOCK" />
