I'll chime in as well that learning Dart is totally trivial. I don't like it all that much, since it really feels like your average Java-based language, but I learned it in a day or two while working on a Flutter app. Flutter is a great framework, and Dart gets the job done. I'm not sure I'd learn Dart apart from Flutter, but if you just treat it as part of learning the framework (think learning ruby along with rails, or Vue's random HTML-esque DSL, which people do), the overall learning curve is not high.
