  "message": "Deprecate AbstractClassInstantiationError.\n\nThe class is no longer used in Dart 2.0 where instantiating an abstract\nclass became a compile-time error.\n\nThe class is now also exported from `dart:mirrors`. Since `dart:mirrors`\nthrows this error when trying to call a constructor mirror from an\nabstract class, it needs to keep having an error to throw.\nFor backwards compatibility, we\u0027ll keep using the same class,\nbut restrict it to `dart:mirrors` and remove it from `dart:core`\nwhen possible.\n\nQ.v. #30771\n\nBug: https://darbug.com/30771\nChange-Id: I2eef6ff8b1509b00b0567cc1951ae9972c87c3fb\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/232605\nReviewed-by: Nate Bosch \u003cnbosch@google.com\u003e\nCommit-Queue: Lasse Nielsen \u003clrn@google.com\u003e\n",
