6 years ago Well, finally i made it work x).
Firstly, this error is generated because region.initFrameworkValue() is not called anywhere through the startMonitoring() methods. After this, i was getting some errors due to the results expected, so i changed the logic a bit.
At Channels.kt, change the startMonitoring() method that containts
launch(UI) {result.successs(beaconsClient.startMonitoring(request)) }`
to
var operation: BeaconsClient.Operation? = null operation = BeaconsClient.Operation(BeaconsClient.Operation.Kind.Monitoring, request.region, request.inBackground) { result ->} beaconsClient.addRequest(operation!!, request.permission) result.success(null)
At channels.dart, change startMonitoring() method return statement to: (returns nothing)
return;// _Codec.decodeResult(response);
After doing this, the new beacon is being monitored withouth any errors. But this doesn't here. This plugin separates the control of monitoring between the listener of Beacons.monitoring() event and Beacons.backgroundMonitoringEvents(). I think this is just usefull when u want to have different beacon monitoring depending on the inBackground attribute. But if u want to manage all beacons in the same listener (that listens the events when the app is in foreground and active) you must do one thing.
In SharedMonitor.kt you must set in attachForegroundNotifier() method:
this.foregroundNotifier = null
and then, in the detachForegroundNotifier() method, comment the line:
// check(this.foregroundNotifier == notifier)
Hope Helped SomeOne!

When I try to use the method Beacons.startMonitoring withouth starting a .monitor listener or stream (but set the backgroundMonitoringEvents method), the app crashes with the following error.
