Oh, I don't mean I hate Dart by any means, I've just written UIs in a lot of languages at this point and would rather use something I'm more familiar with... The one very minor annoyance I've had with Dart that immediately pops to mind, and I think is going to be fixed soon (according to the github issue), is typedefs only working for functions. I personally think it makes things a lot more verbose and unnecessarily difficult to read at times ¯\_(ツ)_/¯
I certainly like it well enough to continue to learn and use both it and Flutter :)
