Motivation

Enable developers to continue processing even when the application transitions to the background, we have created a package that allows processing to continue using location updates.This package was created with reference to background_location.

Can be used when you want to run the program periodically in the background.

• Monitor and notify the distance walked and steps.
• Notification of destination arrival.

Usage

// Monitor notifications of background processes.
BackgroundTask.instance.stream.listen((event) {
    // Implement the process you want to run in the background.
    // ex) Check health data.
});

// Start background processing with location updates.
// Android only: Start Foreground service. If you want to show foreground service notifications, please execute a notification permission request before start.
await BackgroundTask.instance.start();

// Stop background processing and location updates.
await BackgroundTask.instance.stop();

Recommended to use with permission_handler.
