However, calling legacyMakeTypeface will use a default sans-serif font.
This adds in that backup behavior.

Flow
Flow is a simple compositor based on Skia that the Flutter engine uses to cache recorded paint commands and pixels generated from those recordings. Flow runs on the raster thread and uploads information to Skia.
