Support for FFI calls with `@Native external` functions through Native assets on Windows. This enables bundling native code without any build-system boilerplate code. For more info see: * https://github.com/flutter/flutter/issues/129757 ### Implementation details for Windows. Mainly follows the design of https://github.com/flutter/flutter/pull/134031. Specifically for Windows in this PR is the logic for finding the compiler `cl.exe` and environment variables that contain the paths to the Windows headers `vcvars.bat` based on `vswhere.exe`.
Integration tests
These tests are not hermetic, and use the actual Flutter SDK. While
they don't require actual devices, they run flutter_tester
to test
Dart VM and Flutter integration.
Use this command to run (from the flutter_tools
directory):
../../bin/cache/dart-sdk/bin/dart run test test/integration.shard
You need to have downloaded the Dart SDK in your Flutter clone for this
to work. Running ../../bin/flutter
will automatically download it.
Coverage exclusion
These tests are expensive to run and do not give meaningful coverage
information for the flutter
tool (since they are black-box tests that
run the tool as a subprocess, rather than being unit tests). For this
reason, they are in a separate shard when running on continuous
integration and are not run when calculating coverage.
