  "message": "Flow analysis: promote when assigning to variables in patterns.\n\nMost pattern variable assignments don\u0027t need to promote, because\npattern variable assignments must be irrefutable, and thus the pattern\nmatch cannot fail.  There\u0027s one exception, though: when the assigned\nvalue has type `dynamic`, an implicit downcast is performed.\n\nBug: https://github.com/dart-lang/sdk/issues/50419\nChange-Id: Ic8f572303d60c354e9e342f79af03e669fa248c3\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/282381\nCommit-Queue: Paul Berry \u003cpaulberry@google.com\u003e\nReviewed-by: Johnni Winther \u003cjohnniwinther@google.com\u003e\n",
