  "message": "[dart2wasm] Implement weak APIs via delegation to JS\n\nImplement `Expando`, `Finalizer` and `WeakReference` via delegation to\nthe JS `WeakMap`, `FinalizationRegistry` and `WeakRef`, respectively.\n\nThe tests don\u0027t check that the finalizer callback is actually called,\nsince this is nondeterministic. I\u0027ve manually verified that the\ncallback can be triggered by allocating a lot.\n\nChange-Id: If6c440a0d52aaf7afca34238f843fd10b202c143\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/279718\nCommit-Queue: Aske Simon Christensen \u003caskesc@google.com\u003e\nReviewed-by: Joshua Litt \u003cjoshualitt@google.com\u003e\n\nhttps://dart.googlesource.com/sdk/+/531b2afcb5c1ad800f76e6967bf90047a02adf12\n",
