Notes:

------

* This is the companion repository for the `Flutter on Raspberry Pi (mostly) from Scratch` [article](https://medium.com/flutter/flutter-on-raspberry-pi-mostly-from-scratch-2824c5e7dcb1).

* 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](https://github.com/chinmaygarde/raspberrypi_cross_compilation_sdk) 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.
