Reland "[vm/ffi] Add common C types" We're adding these types to `dart:ffi` rather than `package:ffi` so that they can be used with `FfiNative`s. Adds `NativeType`s for the following C types: * unsigned char * signed char * short * unsigned short * int * unsigned int * long * unsigned long * long long * unsigned long long * uintptr_t * size_t * wchar_t Because the C standard only defines minimum sizes for many of these types, future platforms might diverge from the typical size even if all platforms currently agree on a size. To avoid having to reification later, we define all types as AbiSpecificIntegers rather than typedefs, even if all current target platforms agree on the size. Closes: https://github.com/dart-lang/sdk/issues/36140 TEST=tests/ffi/c_types_test.dart Original patch in patchset 1. * Removes `Char` for now until package:win32 has rolled to 2.3.8 in Flutter. https://pub.dev/packages/win32/versions/2.3.8/changelog https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8824468064587445729/+/u/Android_Views_Integration_Tests/stdout * Adds `c_type.dart` in `ffi_source.gni` which should fix `IntPtr` missing when analyzing `path_provider_linux`. (However, I was unable to reproduce the issue locally.) https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8824468064571399025/+/u/run_test.dart_for_flutter_plugins_shard_and_subshard_analyze/test_stdout `/tmp/flutter_plugins.KZMNMC/packages/path_provider/path_provider_linux$ ~/flt/engine/src/out/host_debug/dart-sdk/bin/dart analyze --fatal-infos` Change-Id: I89130cccba285fc9c483bb53f5710a302f2b104f Cq-Include-Trybots: luci.dart.try:dart-sdk-linux-try,dart-sdk-mac-try,dart-sdk-win-try,vm-ffi-android-debug-arm64c-try,vm-ffi-android-debug-arm-try,vm-canary-linux-debug-try,vm-fuchsia-release-x64-try,vm-kernel-gcc-linux-try,vm-kernel-asan-linux-release-x64-try,vm-kernel-linux-debug-x64-try,vm-kernel-linux-debug-ia32-try,vm-kernel-mac-debug-x64-try,vm-kernel-mac-release-arm64-try,vm-kernel-nnbd-win-release-ia32-try,vm-kernel-nnbd-win-release-x64-try,vm-precomp-ffi-qemu-linux-release-arm-try,vm-kernel-win-release-x64-try,flutter-analyze-try,flutter-engine-linux-try,flutter-frontend-try Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/229156 Reviewed-by: Martin Kustermann <kustermann@google.com> Commit-Queue: Daco Harkes <dacoharkes@google.com>
Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
