  "message": "Remove _explicitTypeParameters and substitute4 from FunctionTypeImpl.\n\nsubstitute4 was only used by the kernel resynthesizer, which is not\nbeing maintained at the moment (and which I believe needs to be\nreworked anyhow).  With substitute4 gone, _explicitTypeParameters was\nalways null (except in the case of CircularFunctionTypeImpl, where it\nhad no effect), so we can just replace it with literal `null`.\n\nChange-Id: I5248e0f93b9a39c55d3e4e8b62150536656608e8\nReviewed-on: https://dart-review.googlesource.com/57709\nReviewed-by: Konstantin Shcheglov \u003cscheglov@google.com\u003e\nCommit-Queue: Paul Berry \u003cpaulberry@google.com\u003e\n",
