Yocto Layer for Flutter Engine

meta-flutter

Project Status

Building Engine master for 32-bit and 64-bit. Engine pulls in Clang 11.0. This is used for both build flavors.

Gallery validated on Raspberry Pi 3 64-bit. To get text to show up properly, not only do you need the fonts installed on the target, but the engine needs to be built with fontconfig enabled.

The build uses depot-tools to sync repos, and CI packages. A pre-built Clang toolchain is downloaded as part of the build.
