setBackgroundHandlerRaw method
Stores the raw Dart callback handles on the native side so the foreground service can start a headless Flutter engine when the app is closed.
Implementation
@override
Future<MapxusMethodResponse> setBackgroundHandlerRaw({
required int dispatcherHandle,
required int userCallbackHandle,
}) async {
try {
final result = await _channel.invokeMethod<Map<dynamic, dynamic>>(
'setBackgroundHandler',
{
'dispatcherHandle': dispatcherHandle,
'userCallbackHandle': userCallbackHandle,
},
);
return MapxusMethodResponse.fromMap({
'success': result?['success'] ?? false,
'message': result?['message'] ?? 'Unknown error',
});
} catch (e) {
return MapxusMethodResponse.fromMap({
'success': false,
'message': e.toString(),
});
}
}
