 This project was created to develop **non-official** embedded Linux embeddings of [Flutter](https://flutter.dev/). This embedder is focusing on embedded Linux (eLinux) system use cases. It is also implemented based on Flutter desktop for Windows and has some unique features to use it in embedded systems.

 ## Objective & Goal
 Our objective is to use Flutter in embedded systems. We're developing this embedder to use Flutter in embedded products. Ultimately we would like to propose and contribute this software to the mainline of [Flutter Engine](https://github.com/flutter/engine), which means we would like to add an embedded systems version into the Flutter repo for all embedded developers. Please note that this is just our ideal, not the official opinion of the Flutter community.

+
+The flutter engine takes time to build 6 times (debug profile release * x64 arm64),
+so expect this to take about 1h on a fast machine, and a few hours on anything slower.
+
+The first build will fetch various source directories including flutter
+source dependency tree, following builds will re-use what's available and
+only update as necessary depending on build-all.sh options.
