flutter_display_awake

Keep the device screen awake in Flutter apps.

flutter_display_awake allows your Flutter app to explicitly request a keep-awake state while a specific screen or flow is active (for example, video playback, reading mode, navigation, workouts, or kiosk/check-in pages). When enabled, the plugin asks the underlying platform to prevent automatic screen dimming/locking and display sleep for the current app session; when you no longer need that behavior, you can call keepScreenOff() to immediately restore the system's default power and lock policy. You can also call isKeptOn() to check whether the plugin is currently holding this keep-awake request.

Features

• Keep the screen on (keepScreenOn)
• Restore default sleep behavior (keepScreenOff)
• Query current kept-on state (isKeptOn)

Installation

Add to your pubspec.yaml:

dependencies:
	flutter_display_awake: ^1.0.0

Then run:

flutter pub get

Usage

import 'package:flutter_display_awake/flutter_display_awake.dart';

final plugin = FlutterDisplayAwake();

await plugin.keepScreenOn();

await plugin.keepScreenOff();

bool? isKeptOn;
try {
	isKeptOn = await plugin.isKeptOn();
} catch (_) {
	isKeptOn = null; // If a platform-specific runtime failure occurs.
}

API

Future<void> keepScreenOn()

Requests the platform to keep the screen awake.

Future<void> keepScreenOff()

Restores default platform sleep/lock behavior.

Future<bool> isKeptOn()

Returns whether the plugin is currently keeping the screen on.

Notes

• On mobile and desktop, this plugin controls app/session-level wake behavior. System policies (battery saver, admin policy, OS constraints) may still override it.
• On Web, behavior depends on browser support for the Screen Wake Lock API and page visibility/user interaction rules.

Example

See the runnable sample app in example.
