Notes:

• This is the companion repository for the Flutter on Raspberry Pi (mostly) from Scratch article.
• This repository is only meant to showcase what a minimal embedder might look like. It is not production ready (and never will be)!
• Though this repository is based off of the Raspberry Pi Cross Compilation SDK and GN Sysroot repository. You dont have to use this toolchain or GN.

Flutter on Raspberry Pi

Flutter Embedder for Pi using Broadcom APIs directly.

Prerequisites

• The libflutter_engine.so, icudtl.dat and flutter_embedder.h files for the Raspberry Pi placed in the out/ directory.

Usage for Raspberry Pi

• Download the prepared toolchain, sysroot and related tools to the out directory ./tools/setup_sdk.sh.
  • This takes a while and downloads upto 1 GB of data from cloud storage.
• Prepare the build output directory out with paths to your toolchain using ./tools/setup_gn.sh.
• Build using ninja -C out on your host.
  • Hack and repeat.
• Push your executable to the Raspberry Pi and run.
  • You should probably mount the out directory to the remote Raspberry Pi using SSHFS. That way, the build artifacts automatically end up getting pushed to the Pi.
