[analyzer] Non-null assertion error in AstRewriter #56833

Open parlough opened 2 weeks ago

parlough commented 2 weeks ago

I'm not sure what code was being analyzed when this was triggered, but my current workspace was the SDK when this came from the analysis server.

SDK commit: https://github.com/dart-lang/sdk/commit/7bb6899a2c493b7946ce7ac6290c43050e6068b1
