flutter_midi_engine 0.1.5

Advanced MIDI synthesizer plugin with SF2/SF3 soundfont support for Flutter. Play MIDI notes, load soundfonts, and control multi-channel synthesis on Android and iOS.

0.1.5

• Fixed audio routing on headset/Bluetooth connect & disconnect. Audio now follows the active output device instead of cutting out:
  • Android: registers an AudioDeviceCallback and restarts the MIDI driver when output devices are added/removed so its AudioTrack re-binds to the new route.
  • iOS: configures the AVAudioSession for playback (with Bluetooth A2DP and AirPlay) and observes route-change and interruption notifications, restarting the audio graph so the RemoteIO unit picks up the new device.
• Hardened iOS support: the audio session is now configured and activated at startup, and recovers automatically after interruptions (e.g. phone calls).
• Added support for Flutter 3.44 and Dart 3.12
• Migrated the Android build to built-in Kotlin support (Flutter 3.44 breaking change). The kotlin-android plugin is now only applied on AGP 8 and earlier, so the plugin builds against both AGP 8 and AGP 9 / built-in Kotlin
• Replaced the deprecated kotlinOptions/buildscript Kotlin classpath with the kotlin { compilerOptions { ... } } DSL and bumped the Kotlin JVM target to 17
• Bumped Android compileSdk to 36 and minSdk to 24
• Bumped the minimum iOS deployment target to 13.0
• Fixed placeholder metadata (homepage, author, version) in the iOS podspec
