I get that on my machine too (and in CI), but it appears to be a spurious error in Flutter/Dart internals:

• None of my code is in the stack trace
• The character offset 16741 in controller.dart does not have an error according to anything else (the compiler, the analyzer, etc.)
• The issue goes away for me when I do flutter clean

[shelverizr]

That's very strange. After I ran flutter clean and flutter pub get, I didn't have the same problem even with other projects. Maybe you should add it to the README.

[amake]

I figured it out. The compiler seems to not handle a typedef alias of GlobalKey that doesn't specify any type arg (despite GlobalKey having an @optionalTypeArgs annotation). I'm not sure why cleaning the project prevents the crash.

Regardless I've published a new point release that passes CI, so hopefully this won't annoy anyone else.
