Actually, this isn't shipped to production, so I'm re-opening this issue. This package has been shipped to our hidden testing instance https://dartpad.dev/?channel=dev

Please exercise your suggested package on this instance and confirm here that it works as intended. If you do confirm this as working I'll ship it to stable, beta, master, and old channels on dartpad.dev. If you don't confirm, I won't ship it.

@domesticmouse got this error when running the program with imported dartz package

Error compiling to JavaScript:
Info: Compiling with sound null safety
Error: Couldn't resolve the package 'dartz' in 'package:dartz/dartz.dart'.

Which DartPad channel are you using? If you are on stable, beta, master, or old you will see this error. I've only shipped the expanded package list to the hidden dev channel, referenced in my previous message.

Alternatively, you can supply some test code that exercises the package and I'll confirm it on the dev channel DartPad. Thanks!

From the link above: https://dartpad.dev/?channel=dev

and here's the code:

import 'package:dartz/dartz.dart';

void main() {
  for (int i = 0; i < 5; i++) {
    print('hello ${i + 1}');
  }
}

Looks like it was only added to supported Flutter packages @domesticmouse, not Dart.

Good catch, I'll roll up a fix up PR
