I can't import the package without getting errors. I've migrated my project to null-safety, and now just by importing awesome_select package I get these errors.

got the same error too.

Saulmarti commented 2 years ago

I have de same error. To resolve it i downgrade the version of Flutter, the problem is with the version 1.10 of Flutter.

explorova commented 2 years ago

I hit this error as soon as I upgraded to flutter 2.10.0. My app is not yet using full null-safety, I suspect flutter 2.10 is forcing, or assuming, something along those lines by default.
