Probably not typically needed for an IoT device, but a general app that uses the Iota ledger might be on a mobile device, and the Flutter framework seems pretty handy (I like how it can output iOS and Android code, and probably by now, the browser). And I would think there would be many use-cases for mobile devices. Live search results presented when typing this suggest that access is through REST calls, so it sounds like a Dart wrapper wouldn't be that hard (I just don't now how to do that). So might there be any plans to do this? Thanks.
I am not familiar with Dart. In most languages you are able to write your library in C and create an API in the target language. So, you should take a look into the iota.c library and wrap it in Dart, if possible.
