LGTM.

Thanks, since long running tests are passing, I assume the integration tests on the engine side will also be fine.

Hi. I think somebody should update the Documentation / Getting Started. https://flutter.dev/docs/get-started/codelab, 2020.01.03, says a Web server should be listed in flutter devices. Now accoding to above it is shown only with flutter devices --show-web-server-device.

+1 for appropriate documentation updates. The getting start guide is currently wrong. It took me a while to find this thread to see that the option I was looking for was hidden.

@jonahwilliams what was the rationale behind hiding this option?

[dzianis-dashkevich-old]

just curious, why?
