FIX: resolve MIDI running status correctly on every transport. A device that sends a status byte once and then only data bytes — an M-VAVE SMK-25 Mini
MidiMessageSplitter in flutter_midi_command_platform_interface is the shared MIDI-assembly stage every transport now feeds, and MidiPacket documents the contract they all satisfy: data is exactly one complete MIDI message with all transport framing removed.MidiMessageParser aborts an open SysEx on a status byte rather than burying it in the payload, and bounds its buffer.^1.3.0.One column per quarter.
^1.3.0.FIX: addVirtualDevice, removeVirtualDevice and setNetworkSessionEnabled return Future instead of void. The platform call was previously discarded, so
addVirtualDevice, removeVirtualDevice and setNetworkSessionEnabled return Future<void> instead of void. The platform call was previously discarded, so a failure such as PlatformException(AUDIOERROR, Error -2 while create MIDI virtual source) escaped as an unhandled asynchronous error that no try/catch around the call could see. Await them to handle failures. Existing calls that ignore the result keep compiling; custom MidiCommandPlatform implementations must widen these three overrides from void.setNetworkSessionEnabled(true) rather than at plugin init, so apps using only Bluetooth, USB or virtual MIDI never trigger it. Thanks to @aleksei-svezhevskii for the fix.^1.2.0.addVirtualDevice, removeVirtualDevice and setNetworkSessionEnabled to Future<void>, matching the platform interface.1.2.0 and update the platform interface dependency constraint to ^1.2.0.FIX(ble): retry a connection sequence whose link was torn down mid-handshake. universal_ble reports that as deviceDisconnected rather than a GATT stat
deviceDisconnected rather than a GATT status, so the retry shipped in 1.1.1 did not apply. Unlike a GATT status the code cannot arise from a peripheral that was never reachable, so it is honoured on every platform.^1.1.2.1.1.2 and update the platform interface dependency constraint to ^1.1.2.FIX(ble): retry the whole connection sequence through transient Android GATT_ERROR 133 failures, including failures during service discovery and notif

MIDIPacketList from the original list memory. Packets after the first were read from unrelated memory and anything over 256 bytes was truncated, affecting virtual devices; native devices already had a correct implementation. Virtual device timestamps now report nanoseconds, matching native devices.MidiCommand.sendDataAwaitingDelivery, completing once the transport has written the data rather than queued it, so a bulk transfer can pace against the link rather than a fixed delay. Only the BLE transport observes delivery; platform-routed devices complete immediately, as with sendData.UniversalBleMidiTransport flags useNegotiatedMtu and requestHighPerformanceConnection opt out. These apply on Android, Windows and Linux; on iOS and macOS a connected device is handed over to CoreMIDI, which then owns the write path.MidiCommand.onBleWriteFailure, reporting BLE writes the platform rejected. sendData is fire-and-forget, so this is the only signal that a packet was dropped. Bulk transfers that split a payload across many SysEx messages should treat any event as a corrupted transfer. Silent on Apple platforms for devices handed off to CoreMIDI, which has no equivalent per-write signal, so it complements rather than replaces device-level acknowledgements.0xF7 in every SysEx packet. It was omitted whenever the remaining body was exactly one byte short of the packet size.MidiBleTransport gained onWriteFailure. Classes using implements MidiBleTransport must declare it; extends and all API consumers are unaffected.
