Hmm, haven't seen this one before. The error about Bad state: Tried to use a deleted ScratchSpace seems relevant. That indicates that there may have been some sort of race condition where a new build was scheduled after the resource for the scratch space was disposed.

I would recommend a pub run build_runner clean (or flutter packages run build_runner clean) to unblock yourself.

[samuelsarix]

@jakemac53 flutter clean solved it, but i get it quite often, like every hour or so,i think it might happen when i try to Access localhost while webdev serve just started

This looks like a duplicate of the other issues such as #2362
