One of my goals for libpd is to implement a GUI communication abstraction layer, similar too and possibly building upon the work done for Purr Data's GUI. The end result would you could implement platform or framework-specific drawing but the main logic stays in "Pd land" so you don't have to recreate the widgets themselves as we've done in PdDroiudParty/PdParty. You'd only need to handle "draw rectangle here" etc. This would be similar to how libpd already gives you message and MIDI handling.

When I can get to doing this for real is another question, largely depending on resources and time.

I use Flutter for my day job, which I highly prefer to native iOS and
Android development.

(If I ever have the time and energy, I am considering rewriting MobMuPlat
in Flutter, which would unite 4 separate implementations (iOS, Android,
Java Swing for desktop, MacOs) into a single implementation.)

While a Flutter GUI (and other layers of the app, e.g. data layer,
controllers, etc) is cross-platform, you will still need to have a 'native'
layer for iOS and Android in order to handle libpd integration and its
interaction with per-platform audio APIs. But that would operate the same
as existing iOS and Android native apps which use libpd; you would merely
add a 'plugin' wrapper (i.e. a Dart library which translates app logic into
calls to the native layer).
