See FlutterChannels.mm

FlutterBinaryMessenger is strongly referenced in FlutterMethodChannel. If the FlutterBinaryMessenger is a FlutterViewController, then this channel should be strongly referenced so that it can work, as the result the FlutterViewController is strongly referenced too. There is no callback for the controller finally releasing so that I can remove this channel.

Is that FlutterBinaryMessenger in FlutterMethodChannel supposed to be weak reference.
