Flutter for Embedded Linux (eLinux)

This software is a non-official extension to the Flutter SDK to build Flutter apps for Embedded Linux devices.

Objective

Our objective is to use Flutter in embedded systems. We're developing this embedder to use Flutter in embedded products. We would be grateful if you could give us feedback on bugs and new feature requests. We would like to cover the specifications of general-purpose embedded systems.

Features

• Flutter optimized for Embedded Systems
  • Minimal dependent libraries
  • Lightweight than Flutter desktop for Linux (Not using X11 and GTK)
  • arm64/x64 devices support
• Display backend support
  • Wayland
  • Direct rendering module (DRM)
    • Generic Buffer Management (GBM)
    • EGLStream for NVIDIA devices
• Keyboard, mouse and touch inputs support
• Equivalent quality to Flutter desktops
• API compatibility with Flutter desktop for Windows and GLFW
  • APIs such as MethodChannel and EventChannel are completely the same with them

If you want to know more details, see also flutter-embedded-linux, which is flutter embedder for eLinux.

Quick start

Install flutter-elinux

$ git clone https://github.com/sony/flutter-elinux.git
$ sudo mv flutter-elinux /opt/
$ export PATH=$PATH:/opt/flutter-elinux/bin

Install required tools

$ sudo apt install curl clang cmake pkg-config

Run Flutter sample app in Weston

You need to install a Wayland compositor such as Weston and launch it before launching your Flutter apps. Note that if you use Weston, Weston version 8.0 or above recommended. See also: Support status

$ sudo apt install weston
$ weston &

$ flutter-elinux devices
2 connected devices:

eLinux (desktop) • elinux-wayland • flutter-tester • Ubuntu 20.04.2 LTS 5.8.0-63-generic
eLinux (desktop) • elinux-x11     • flutter-tester • Ubuntu 20.04.2 LTS 5.8.0-63-generic

$ flutter-elinux create sample
$ cd sample
$ flutter-elinux run -d elinux-wayland

If you want to run your flutter app in X11, use elinux-x11 instead of elinux-wayland:

$ flutter-elinux run -d elinux-x11
