How can I pull AppLifecycleState.resume in Flutter when the application's state is AppLifecycleState.paused?

Body

My application is an information screen application that works on a tablet 24 hours a day. That's why it should never turn off from the screen. But sometimes it falls off the screen and continues to run in the background. Can I trigger it to run on the screen again when it falls into the background with codes? I can print lifecycle states, but I cannot change their states.

Thanks in advance for your answers

Absolutely! In Flutter applications, you can't directly control whether your app stays on the screen or not. Operating systems like Android and iOS manage app lifecycle transitions based on various factors such as user interactions, system resources, and power-saving mechanisms.

However, you can make your app more resilient to being sent to the background by handling lifecycle events appropriately and potentially implementing features to mitigate the impact of being in the background. Here are some strategies you can consider:

Handle Lifecycle Events: Flutter provides lifecycle callbacks that you can use to respond to changes in your app's lifecycle. For example, you can use the didChangeAppLifecycleState method in the WidgetsBindingObserver mixin to detect when your app transitions between states like resumed, paused, inactive, and detached.
Keep the Screen On: While you can't force your app to stay on the screen indefinitely, you can request that the device's screen remains on while your app is in the foreground. This is typically done using the flutter_screen_keep_on package or platform-specific APIs.
Foreground Service (Android): On Android, you can create a foreground service to give your app higher priority and reduce the chances of being killed by the system. This won't guarantee that your app stays on the screen, but it can help keep your app running in the background.
Optimize Resource Usage: Ensure that your app is optimized for performance and resource usage. Excessive CPU, memory, or battery usage can cause the system to prioritize other apps over yours, leading to it being sent to the background or killed.
Handle App Restoration: When your app is brought back to the foreground, ensure that it can restore its state and resume where the user left off seamlessly. This includes restoring navigation stacks, input fields, scroll positions, etc.
While these strategies can improve the user experience and resilience of your app, they can't completely prevent your app from being sent to the background or killed by the operating system. Design your app to handle these scenarios gracefully and provide a seamless experience for users.

Thank you very much for your answer. I will re-evaluate my application with this information.
