  "message": "[model] Update handling of ?.length in constants\n\nThis adds reporting of an error in CFE for ?.length in constant expressions and improves the message for the analyzer in the same case. The error in the analyzer was previously the invalid claim that\n\n    The property \u0027length\u0027 can\u0027t be accessed on the type \u0027Null\u0027 in a constant expression.\n\nCloses #60509\n\nChange-Id: Ibbe0fa1ace3bea9d83efea2ccf3ea9716a125d74\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/421841\nReviewed-by: Konstantin Shcheglov \u003cscheglov@google.com\u003e\nCommit-Queue: Johnni Winther \u003cjohnniwinther@google.com\u003e\nReviewed-by: Brian Wilkerson \u003cbrianwilkerson@google.com\u003e\n",
