About the start function

[darshansatra1]

When we call
await FlutterForegroundTask.start( notificationTitle: "Today: $steps steps", notificationText: 'Yesterday: $yesterdaySteps steps', callback: periodicTaskFun, );
Does this call creates a new isolate or is the service still running in the main isolate?

When the FlutterForegroundTask.start function is called, a new isolate is created separate from the main isolate. The isolate of dart has a separate memory area unlike the threads used in other languages. Therefore, periodicTaskFun is executed in the new isolate and the event is called periodically by creating a background method channel through FlutterForegroundTask.initDispatcher function.

If you want to share data with an isolate that has separate memory areas, try the sqflite plugin.

As I am still learning, it may not be a perfect answer, but I hope it helps you :)

Yaa I faced the issue in Hive, since Hive doesn't support multi-threading. So I switched to object box which had better performance than sqflite and also supports multi-threading.
