Looks like some of those deprecated names have finally been removed/renamed.

It's not hard to fix, but unfortunately would mean removing support for Dart 1 - which is probably ok - or creating two packages (one for Dart 1, one for Dart 2), which is annoying.

[dnfield]

Yes, they were removed 8 days ago now - dart-lang/sdk@f2402b3

My preference would be to add an environment constraint (say, sdk: '>=2.0.0-dev.28.0 <3.0.0', which follows what a lot of the official Flutter plugins currently have), and update the constants. I can create a PR for that and maybe collect feedback there.

@aardappel this will require publishing a new Dart package to dart pub, but users could in theory refer directly to the git repository for now.

[dnfield]

Also, this would be a great candidate for dart-lang/sdk#33249 - could conditionally wrap code with these references rather than needing to worry about how to support users who might still want to use Dart 1.x

That said, there is a working version of this lib that would still support Dart 1.x...
