A huge amount of people out there try to avoid JS like the plague, hence the popularity of TypeScript, so yep, if I can learn Dart in an afternoon and have the ability to write hybrid mobile apps then it's plenty worth it.

Re "Angular, one of Google most successful projects, uses TypeScript and not Dart, let that sink in.": Google is also promoting AngularDart as well, "Hundreds of Google engineers use AngularDart to build the sophisticated, mission-critical apps that bring in much of Google’s revenue." https://webdev.dartlang.org/angular/

"Demise of so many projects from Google" I agree with (sans the popularity of Go).

Flutter is in alpha so time will tell if Google will put enough funding/focus into it.
