Unhandled Exception: MissingPluginException(

[pp2015jp]

Dear Sir

Any idea for...

E/flutter: [ERROR:flutter/lib/ui/ui_dart_state.cc(171)] Unhandled Exception: MissingPluginException(No implementation found for method play_midi_note on channel flutter_midi)
#0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:158)

#1 FlutterMidi.playMidiNote (package:flutter_midi/flutter_midi.dart:69)

#2 _MyAppState._play (package:melody/main.dart:552)

I got your same error message, I just used the _flutterMidi.playMidiNote method and debugging deeper (myCode + package) I got this exception:

Unhandled Exception: PlatformException (error, attempt to invoke interface method 'void jp.kshoji.javax.sound.midi.Receiver.send (jp.kshoji.javax.sound.midi.MidiMessage, long)' on a reference of null, null object, java.lang.NullPointerException: Attempt to invoke interface method 'void jp.kshoji.javax.sound.midi.Receiver.send (jp.kshoji.javax.sound.midi.MidiMessage, long)' on a null object reference

I hope @rodydavis will solve this bug soon.
