  "message": "[vm/aot/tfa] Introduce TFA-specific representation of classes (refactoring)\n\nNew class representation is used in ConcreteType and ConeType instead of\nDartType. Uses of pre-NNBD legacy raw types are eliminated in most cases.\nThis also simplifies subtype checks.\n\nTypesBuilder class is created to translate static types into\nTFA types. It holds CoreTypes which is used to recognize Null class\nand supersedes Type.cone and Type.fromStatic factory constructors.\n\nChange-Id: Ia1cd48cf8c738173a06dd04864f6cec8ae6def83\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/124286\nCommit-Queue: Alexander Markov \u003calexmarkov@google.com\u003e\nReviewed-by: Ryan Macnak \u003crmacnak@google.com\u003e\n",
