Add null safety

[enyo]

It would be great if grpc-dart would add support for null safety.

Yes, we are planning to migrate the package.

@mraleph now that null safety is in beta, will there be a published nullsafety release soon? https://medium.com/dartlang/announcing-dart-null-safety-beta-87610fee6730

[mraleph]

Once all dependencies are migrated this package will also be migrated. I don't know about the timelines though - I am not involved in migration planning.

For anyone following this issue: the null-safety PR has been merged! 🎉

I'm going to leave this issue open until it is published on pub.

googleapis_auth has published – you should be unblocked!

[mraleph]

It is published on pub as a prerelease :)
