Not quite sure where to triage this to...

This looks like a misuse of ScratchSpace. @jonahwilliams - do you know if this is coming strictly from build_modules, or is there other uses of package:scratch_space that could be the problem?

[jonahwilliams]

I'm not using a scratch space directly in the flutter tool or in the flutter web build script

[jakemac53]

This might just be a slightly different manifestation of https://github.com/dart-lang/sdk/issues/38102, possibly pointing at more of a root cause?

One theory could be that we are for some reason considering a build step to be completed before it is actually done (for an unknown reason). Meanwhile the compiler is actually still running, and the scratch_space gets deleted out from under it.

[jakemac53]

@ajs-sonawane is it possible to get a full log for this (I realize it might be quite verbose).
