This fails because I manually updated the pubspec, but shows the changes necessary to use a 0.7.x dwds. We also expect to have a 0.7.1 with a few more fixes for Flutter issues very shortly.

Sounds good - you can update the pubspecs for this PR with flutter update-packages --force-upgrade FWIW

[alan-knight]

OK. I had been reluctant to do that for fear of coupling it to other things, but did it now.

[jonahwilliams]

Ahh I see you ended up with the build_runner roll too. Could you update these lines:

https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/build_runner/build_script.dart#L219

To remove the skipPlatformCheckPackages and replace it with skipPlatformCheck: true?

If not, I can take over this PR to finish it

[alan-knight]

Added the build_runner fix.

[jonahwilliams]

Sorry, looks like there is one more at packages/flutter_tools/lib/src/build_runner/build_script.dart:245

[DanTup]

🎉

[jonahwilliams]

Looks like we managed to roll this in with #41936

[alan-knight]

OK.
