I'm working on a Flutter app with some native kotlin code. It's straightforward to call native methods from Flutter through the MethodChannel, and vice-versa (from MainActivity).

However, I also want a way to trigger Flutter code triggered from a native Broadcast receiver, where I don't have the original MethodChannel. The problem is, I'm not sure how to create a FlutterEngine with the right arguments to get access to the same MethodChannel.

Is there a way to construct the same FlutterEngine that can be used to call back into Flutter code? What I want to do:

var flutterEngine = FlutterEngine(XXX)
var flutterChannel = MethodChannel(flutterEngine.dartExecutor.binaryMessenger, FLUTTER_CHANNEL)
flutterChannel.invokeMethod(...)

I'm not sure what XXX should be here to get the same Channel I have in MainActivity. If there's some info I need to pass from MainActivity, I could use intents to pass it to my broadcast receiver, but it's not clear what is needed.

Flutter Engine and Channels work with named scopes, if you uses the same engine name end channel is the same channel in Flutter side.

  • Thanks, I got the engine / channel names (engine is created by flutter, but I printed out the name), but engine / channel don't seem to have a constructor that takes a name. Channel needs a binaryMessenger, which is a property of the engine, and I'm not sure how to construct the engine with just a name. – xcoder Mar 18 '20 at 00:28
