Typescript fits my sensibilities and desire for expressive type-systems much more than Dart.

Back when I tried it, it also had a much more incomplete ecosystem, though the google marketing machine was in full swing. I remember not being able to even use the sqlite library without actually spinning up an emulator (as in, I couldn't use it with just plain dart). Dealing with generics was actually difficult/painful (as in just something simple like printing JSON). BLoC seemed like a hack and was more complex than I was comfortable with for using at large scale. Maybe it's better these days.

I will take Typescript over Dart all day every day. I would even take JS with all it's warts over Dart.

That said, Flutter I think is amazing because it is probably going to be hands-down the easiest way to write apps that hit a large number of screens. I think Google will get there first-ish (they have a lot of money and a lot of platforms to support).
