Building for web fails with javascript compilation errors

I'm able to build for other platforms just fine, but when attempting to build for the web it throws the following errors.

Launching lib/main.dart on Chrome in debug mode...

Seems like all the fixes need to happen at the pointcastle repo. I've opened an issue there. Should I close this or keep it open until it's fixed there?

Worth mentioning that this library can temporarily depend on a version of pointycastle which doesn't have this regression, because crypton doesn't use Argon2. That would be (I think) 3.1.0, but you can check the changelog - whatever is before the Argon2 update will work.

Yes, you're right. 3.1.1 actually works fine. Created a simple PR that just sets the dependency in pubspec.yaml to 3.1.1.
