  "message": "Reland \"[vm/ffi] Introduce `Struct.create` and `Union.create`\"\n\nAnalyzer fix https://github.com/dart-lang/sdk/issues/54754 has\nlanded. A new version of package:analyzer and package:dartdoc have\nbeen released. `pub global activate dartdoc` should now work.\n\nPatchset 1 is identical to the original CL.\nThe only difference is an extra test testing with negative offsets.\n\n\u003d\u003d\u003d Original CL description \u003d\u003d\u003d\n\nStructs and unions can now be created from an existing typed data\nwith the new `create` methods.\n\nThe typed data argument to these `create` methods is optional. If\nthe typed data argument is omitted, a new typed data of the right\nsize will be allocated.\n\nCompound field reads and writes are unchecked. (These are\nTypedDataBase loads and stores, rather than TypedData loads and stores.\nAnd Pointers have no byte length.) Therefore the `create` method taking\nexisting TypedData objects check whether the length in bytes it at\nleast the size of the compound.\n\nTEST\u003dpkg/analyzer/test/src/diagnostics/creation_of_struct_or_union_test.dart\nTEST\u003dpkg/vm/testcases/transformations/ffi/struct_typed_data.dart\nTEST\u003dtests/ffi/structs_typed_data_test.dart\nTEST\u003dtests/ffi/vmspecific_static_checks_test.dart\n\nCloses: https://github.com/dart-lang/sdk/issues/45697\nCloses: https://github.com/dart-lang/sdk/issues/53418\n\nChange-Id: Id7f30bcd4a6ae55a8298b39c9eadf4e80bc699a9\nCoreLibraryReviewExempt: FFI is a VM and WASM only feature.\nCq-Include-Trybots: luci.dart.try:vm-aot-android-release-arm64c-try,vm-aot-android-release-arm_x64-try,vm-aot-linux-debug-x64-try,vm-aot-linux-debug-x64c-try,vm-aot-mac-release-arm64-try,vm-aot-mac-release-x64-try,vm-aot-obfuscate-linux-release-x64-try,vm-aot-optimization-level-linux-release-x64-try,vm-aot-win-debug-arm64-try,vm-aot-win-release-x64-try,vm-appjit-linux-debug-x64-try,vm-asan-linux-release-x64-try,vm-checked-mac-release-arm64-try,vm-eager-optimization-linux-release-ia32-try,vm-eager-optimization-linux-release-x64-try,vm-ffi-android-debug-arm-try,vm-ffi-android-debug-arm64c-try,vm-ffi-qemu-linux-release-arm-try,vm-ffi-qemu-linux-release-riscv64-try,vm-fuchsia-release-x64-try,vm-kernel-linux-debug-x64-try,vm-kernel-precomp-linux-release-x64-try,vm-linux-debug-ia32-try,vm-linux-debug-x64-try,vm-linux-debug-x64c-try,vm-mac-debug-arm64-try,vm-mac-debug-x64-try,vm-msan-linux-release-x64-try,vm-reload-linux-debug-x64-try,vm-reload-rollback-linux-debug-x64-try,vm-ubsan-linux-release-x64-try,vm-win-debug-arm64-try,vm-win-debug-x64-try,vm-win-release-ia32-try\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/349260\nReviewed-by: Martin Kustermann \u003ckustermann@google.com\u003e\n",
