Description
Introduced at WWDC 2020, Metal Binary Archives speed up creation of pipeline state objects. In Flutter, these objects are created as necessary within a frame workload on the raster thread. This can cause jank. Investigate persisting these archives (shipping them if possible in the application bundle) and loading them (possibly via the Skia persistent cache interface) at runtime to reduce jank during startup.
