Seen behavior

lib\hello_bindings_generated.dart contains no bindings.

Expected behavior

lib\hello_bindings_generated.dart contains bindings for sum and sum_long_running.

Steps to reproduce

On Windows:

1. flutter create --template plugin_ffi hello
2. cd hello
3. flutter pub run ffigen --config ffigen.yaml

Root cause

Path separator on Windows not converted to backslash:

• Bindings are not generated for files declared under "include-directives:" dart-lang/native#239

Fix

Bump package:ffigen to a new version after landing:

• Fix include-directives on Windows dart-archive/ffigen#397

Testing

We should possibly also add a test exercising the run of the bindings generator on the bots, but this requires having libclang available.

On the package:ffigen bots we use GitHub workflows.

      - name: Install libclang-10-dev
        run: sudo apt-get install libclang-10-dev

@stuartmorgan Do we have libclang on the Flutter bots? Can we have this on the bots?
