  "message": "[analyzer] Fix null shorting extent in cascade sections.\n\nWhen a cascade section contains a null-aware expression, the null\nshorting should be terminated at the end of the cascade section. For\nexample, in the statement:\n\n    e..x?.f()..g();\n\nif `e.x` evaluates to `null`, the call to `f()` should be skipped, but\nnot the call to `g()`.\n\nPrior to this fix, the analyzer erroneously considered the null\nshorting to be terminated at the end of the entire cascade. The\nmistake wasn\u0027t easily observed, since the analyzer doesn\u0027t have\nback-end semantics. But it was still observable in some rare cases\ninvolving type promotion. For example, in the statement:\n\n    e..x?.f(i!)..g(i!);\n\nthe analyzer would consider the second `!` to be unnecessary, because\nin its model of flow control, `g(i!)` would only ever execute after\n`f(i!)`.\n\nFixes https://github.com/dart-lang/sdk/issues/59658.\n\nBug: https://github.com/dart-lang/sdk/issues/59658\nChange-Id: I8540daca121dac6960f8d6a2a3ffa3e38a0bf921\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/398926\nAuto-Submit: Paul Berry \u003cpaulberry@google.com\u003e\nReviewed-by: Konstantin Shcheglov \u003cscheglov@google.com\u003e\nCommit-Queue: Paul Berry \u003cpaulberry@google.com\u003e\n\nhttps://dart.googlesource.com/sdk/+/922f212340fd10b041a1659c8571a69f3e6f6370\n",
