Code breakdown

<runtime_mode>_<arch>/libflutter_engine.so

These are builds of the Flutter embedder platform for OS_FUCHSIA with --runtime-mode=<runtime_mode> and --cpu=<arch>.

These builds contain a few changes that have not been landed into the Flutter Engine repository:

1. Add -fPIC to Fuchsia builds.
2. Fix JIT snapshot support for the embedder platform.
3. Hack to workaround http://fxbug.dev/75282.
4. Add support for acquiring software surface to embedder API.

These changes should be landed and libflutter_engine.so should be pulled from a CIPD bucket instead.
