Google is using Dart as the programming code for the OS, and Flutter for the user interface.
The OS will support 32-bit and 64-bit ARM CPUs, and also 64-bit PCs.
According to an Android Police report, Google hopes to replace Android and Chrome OS with Fuchsia.
LK is a kernel designed for small systems typically used in embedded applications.
According to Geiselbrecht, we should also see Fuchsia running on a Raspberry Pi 3 in the near future.
