As you aware, there are so many developers like myself moving away from other platforms and using Flutter as their favorite tool for mobile development. I think it would be a wise business decision to add support for flutter also.
I forked flutter_zoom_plugin to fix this error:
GitHub - driftboat/flutter_zoom_plugin: Flutter plugin for zoom
And you need work on flutter master channel, they fixed “plugin java class desugar” (https://github.com/flutter/flutter/pull/73758) on this channel.
