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. The changes are cherry-picked into the Flutter Engine build here.

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