[kaby76]

For any grammar in grammars-v4, e.g., abb. error(31): ANTLR cannot generate Dart code as of version 0.6.0

This seems to fix some things.

Odd, how comes this wasn't there before? I'm also pretty sure I have once created Dart files.

Is this all what's needed to fix this issue?

[kaby76]

I thought I tested it, but maybe not. But, it's all being tested side-by-side with the old Antlr tool (with antlr/grammars-v4#4385). I think these changes fix the problem, but I haven't checked. Maybe you can make the changes, and I'll test it locally on my machine?

[mike-lischke]

OK, will do as soon as I can.

That solved it @kaby76, thanks!
