The master version of that file has numbers suffixed into the IDs:

So the issue here is that the IDEs don’t know which host flutter create is going to use (I think we both just assumed the stable host is fine, and there wouldn’t be breaking changes). The logic Flutter uses is checking which channel it’s on, though it feels a bit clunky for the editor to start checking that.

Maybe we could make a flutter create --list so that IDEs can get the same JSON that matches what flutter create supports? It can just fetch the JSON and spit it out, but use the same internal logic for checking the hostname to avoid it leaking out?
