  "message": "Reland: [cfe] Embed and use allowed experiments in CFE\n\nThis CL embeds the sdk_nnbd/lib/_internal/allowed_experiments.json\ninto the CFE and uses this to allow experiments enabled on a\nper library basis. The file is embedded through generated code to\navoid reliance on access to the file itself.\n\nA presubmit check is also added to ensure that the json file and\nthe generated code are in sync.\n\nThis work is in preparation for https://github.com/dart-lang/sdk/issues/41538\n\nThis was reverted in https://dart-review.googlesource.com/c/sdk/+/149620\nbecause flutter wasn\u0027t prepared for auto-enabling nnbd in dart:* libraries.\nThis has now been fixed in https://github.com/flutter/engine/pull/18714\n\nCloses #42162\n\nChange-Id: I686ed6feaef8ee066b426068fe2a0f5080bf1713\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/149588\nReviewed-by: Jens Johansen \u003cjensj@google.com\u003e\nCommit-Queue: Johnni Winther \u003cjohnniwinther@google.com\u003e\n",
