Not really.

For personal projects or if you're a freelancer sure. Once you work in a company/startup you can't go and implement things in whatever you like.

It's way easier to convince any manager that Dart/Flutter is a good choice for a mobile app because of the tech advantages than in anything else because of the pool of available developers.

Man, the context of question, is how to use Dart in a Typescript/React application (because of popularity of ReactJS ecosystem, of course).

Any way to use Dart with React in a .jsx way? It looks like Dart has exclusive support for Flutter, and that's it.
