How to use in background

[singhmukesh2023]

I need to compress video in the background to free the user interface. I am using workmanager for background and ffmpeg_kit_flutter_new for compressing. I got exception on compressing.

ffmpeg_kit_flutter_new: ^4.1.0
workmanager: ^0.9.0+3

I execute the compress cmd in WorkManger.executeTask().

@pragma('vm:entry-point')
void callbackDispatcher() {
Workmanager().executeTask((task, inputData) async {
print("Background task: $task");
// Your background work here
return Future.value(true);
});
}

Exception
The following MissingPluginException was thrown while activating platform stream on channel flutter.arthenica.com/ffmpeg_kit_event: MissingPluginException(No implementation found for method listen on channel flutter.arthenica.com/ffmpeg_kit_event)
