Error flutter pub get with Dart SDK 2.9.2 Flutter 1.20.4

[VinciShark]

Really love this package, but meet problem when using it

The current Dart SDK version is 2.9.2.

Because build_runner >=1.10.2 requires SDK version >=2.10.0-0.0 <3.0.0 and build_runner >=1.10.0 <1.10.2 depends on build >=1.3.0 <1.4.0, build_runner >=1.10.0 requires build >=1.3.0 <1.4.0.
And because every version of built_path depends on build ^0.12.7, build_runner >=1.10.0 is incompatible with built_path.
So, because clarinet_mini depends on both built_path ^0.1.0 and build_runner ^1.10.0, version solving failed.
pub get failed (1; So, because clarinet_mini depends on both built_path ^0.1.0 and build_runner ^1.10.0, version solving failed.)
Process finished with exit code 1

I'd be happy to review a PR that fixes this - I have not really done much with this in some time.
