flutter_midi_command_web 1.0.3

The web implementation of flutter_midi_command, using the browser Web MIDI API to send and receive MIDI messages.

flutter_midi_command_web

Web implementation of flutter_midi_command backed by the browser Web MIDI API.

What it supports

• Enumerating MIDI input/output ports as MidiDevice
• Connecting/disconnecting to discovered devices
• Receiving MIDI packets from input ports
• Sending MIDI packets to output ports
• Emitting setup-change events when browser MIDI ports appear/disappear

What it does not support

• Virtual MIDI devices (addVirtualDevice / removeVirtualDevice)
• iOS/macOS network session APIs (isNetworkSessionEnabled / setNetworkSessionEnabled)
• BLE via flutter_midi_command_ble on web

Browser requirements

• HTTPS origin (or localhost during development)
• Browser with Web MIDI API support (typically Chrome/Edge)
• User permission granted for MIDI access

If the browser does not expose navigator.requestMIDIAccess, API calls will throw UnsupportedError.

Notes on permissions and SysEx

The implementation requests MIDI access with SysEx enabled (sysex: true). If SysEx permission is denied by the browser/user policy, initialization may fail and surface as an error from devices/connectToDevice.

Testing

This package includes backend-injected unit tests in test/flutter_midi_command_web_test.dart. Run in a browser with:

flutter test --platform chrome
