Keep the screen always on

[DartViet]

Our company is making an app with the requirement that whenever it's running in the foreground, the screen should never turn off.

So far, we've been calling WakeLockPlus.enable() in main(), but we saw a note on the plugin's page that says, "The wakelock can be released by external sources at any time (e.g., by the OS). Only calling WakelockPlus.enable() once will most likely mean that the screen turns off at one point or another anyway."

So, in our case, what's the solution for our app to keep the screen from turning off? We currently have two possible solutions:

1 Using Flutter lifecycle in "MyApp" class, so whenever the app is resumed, we enable to WakeLockPlus again, like this:

   @override
    void didChangeAppLifecycleState(AppLifecycleState state) {
        if (state == AppLifecycleState.resumed) {
            // Perform actions when the app is resumed
            Wakelockplus.enable();
            // e.g., refresh data, re-authenticate, etc.
        }
    }

2 Using Timer, periodically call Wakelockplus.enable()

Thank you.

@DartViet you should ideally use

• One dictated by business logic: Playing a video should enable the wakelock and pausing/stopping it should release it.
• And another dictated by lifecycle: If my video was playing when entering the background, pause the video and release the wakelock. Once back to the foreground, if my video was previously playing when going through a lifecycle event, it should resume it and enable the wakelock.

Hopefully this makes sense for your use case. Please feel free to ask questions.
