Getting Started

This plugin is build using Swift and Kotlin on the native side, so make sure your project supports this.

Import flutter_midi_command

import 'package:flutter_midi_command/flutter_midi_command.dart';

  • Get a list of available MIDI devices by calling MidiCommand().devices which returns a list of MidiDevice
  • Start scanning for BLE MIDI devices by calling MidiCommand().startScanningForBluetoothDevices()
  • Connect to a specific MidiDevice by calling MidiCommand.connectToDevice(selectedDevice)
  • Stop scanning for BLE MIDI devices by calling MidiCommand().stopScanningForBluetoothDevices()
  • Disconnect from the current device by calling MidiCommand.disconnectDevice()
  • Listen for updates in the MIDI setup by subscribing to MidiCommand().onMidiSetupChanged
  • Listen for incoming MIDI messages on from the current device by subscribing to MidiCommand().onMidiDataReceived, after which the listener will recieve inbound MIDI messages as an UInt8List of variable length.
  • Send a MIDI message by calling MidiCommand.sendData(data), where data is an UInt8List of bytes following the MIDI spec.
  • Or use the various MidiCommand subtypes to send PC, CC, NoteOn and NoteOff messages.
