Update to Dart 2.0 🎉

[leerob]

• Ran over_react_codemod on the codebase
• Updated versions in the pubspec.yaml and got pub get to run successfully
• Updated the components pulled from the over_react examples
• Updated documentation

Hopefully you guys (@evanweible-wf @corwinsheahan-wf and crew) can use this as an example for people migrating as you roll out Dart 2 support. I've been monitoring analytics on my blog post (here) that uses this tutorial and it's still getting ~100 views per week, as well as ranking on Google when you search "Dart React", so I'm hoping to get this updated so it's accurately promoting Workiva OSS.

@leerob I think this should take care of the build failure you're seeing: #4

[leerob]

That worked! I'm able to run locally now 🎉

I'll work on getting the documentation/blog post updated.

[leerob]

Hmmm. Running pub run build_runner test locally does not work. ddev test also doesn't work. Is there further configuration needed for either of those? I'm surprised it works on Travis but not locally.

Should I be recommending using build_runner test for now, or ddev test? @evanweible-wf

I've got the docs mostly updated now, should be almost ready.

@leerob Looks like your dev.dart file is set up correctly. I didn't have any issue running tests via ddev test. What's the error you're seeing?

[evanweible-wf]

@leerob pub run build_runner test works for me locally on the latest commit. It's possible that that your .dart_tool/build/ directory got in a bad state from the failed build you were encountering earlier, could you try removing that directory and then running a build/tests again?

I think recommending build_runner test in this project makes the most sense. At this point ddev test isn't doing a whole lot and running build_runner test will probably become more common on Dart 2 so it'd be good to make people familiar.

@evanweible-wf @corwinsheahan-wf Yep, that appeared to be the issue. Blowing away .dart_tool fixed the issue and pub run build_runner test ran successfully.

Maybe I can swing back and update this to use ddev test in the future, since the -n is helpful as projects scale.

[leerob]

Woohoo! 🎉 The blog post has been updated (leerob/site#6) and is live here.

I'll probably post it to /r/dartlang to try and get some eyes on OverReact 2.0 when it's released (Workiva/over_react#240).

[evanweible-wf]

Maybe I can swing back and update this to use ddev test in the future, since the -n is helpful as projects scale.

That's actually a feature of the test package itself, ddev test just proxies the flag. You can pass whatever flags you'd like to the underlying test runner like so:

pub run build_runner test -- -n 'pattern'

And thanks, much appreciated! 2.0 should be published tonight or tomorrow morning.
