> Ecosystem is small, but at least there's FFI interop. FFI continues to be a disaster (to be fair, this is not unique to Dart/Flutter). The biggest problem with any cross-platform system on mobile is always getting performance out of the native interop. It's often easier to ship a computation to a server on the web and ship teh result back rather than execute it natively on another thread on the bloody phone. It's infuriating. We have a zillion cores, and every single phone OS tries it's damnedest to prevent you from using them because, heaven forbid, you might actually use up some of the battery. The Horror! The Horror! The cross-platform systems for phones are really good at doing puzzle games or CRUD. Step outside of that and you enter "Here Be Dragons" territory very quickly.
