Dart was being pushed as JavaScript replacement, back when everyone had one.
However Chrome team failed to push ChromiumVM and eventually the project was ramped down, by then AdWords had made a massive investment moving from GWT into AngularDart, so they rescued the project.
Eventually Flutter, initally prototyped in JavaScript, moved into Dart, and they also decided to change the language semantics from dynamic language with gradual typing (Dart 1.x), to static typing with type inference (Dart 2.0).
Somewhere alongside this timeline, many well known names from language design like Gilad Bracha and Kasper Lund, well known for favouring dynamic languages, left the project.
Kasper Lund's latest project, is not surprising also a dynamic language, https://toit.io/
I guess I am trying to understand why these two coexist, which one to learn, and how likely it is that Google will kill Dart/Flutter in the next 5-10 years.
It is all about Java, Kotlin, C, C++, Web widgets and PWAs.
I am not a big Kotlin fan, the way Android has pushed it using their Android Java as counter example instead of supporting modern Java, however as JVM language it definitely has a broader industry support than Dart.
Honestly, Flutter is an amazing framework conceptually, but Dart may prove to be its demise. I just hope there is a possibility for Flutter based on Typescript or Kotlin in the future.
