Do you personally use it? That "strong mode" is a theory-only thing, it doesn't work with any real code, only with code you wrote without real third-party libraries.

You are, at best, confusing Dart 2 with Dart 1; strong mode was one of several Dart 1 modes, but, yes, it's possible to run into problems because dependencies weren't designed for it.
There is no option in Dart 2; everything is the equivalent of strong mode, which eliminates ecosystem problems.

I mentioned I've only tried Dart 1.x. Glad to hear it's changed in Dart 2.

Your claim was true several years ago, but since then the entire ecosystem has migrated onto the new strict type system. It was a monumental amount of work, but, thanks to lots of effort from our users, we're there.
Aside from a small number of more-or-less dead packages, you should be able to use any third-party Dart packages you want while still using the new type system.
Dart's developers think otherwise[1]:
