Flutter for Embedded Linux (eLinux)

This software is a non-official extension to the Flutter SDK to build and debug Flutter apps for Embedded Linux devices using flutter-embedded-linux, which is the flutter embedder for eLinux.

Features

• Flutter optimized for Embedded Systems
  • Lightweight than Flutter desktop for Linux (Not using X11 and GTK)
  • arm64/x64 devices support
  • Minimal dependent libraries
• Embedded software development
  • Cross-building from x64 to arm64 support
  • Install/uninstall/debug to remote target devices
• Flutter plugins support
• Display backends
  • Wayland
  • Direct rendering module (DRM)
    • Generic Buffer Management (GBM)
    • EGLStream for NVIDIA devices
  • X11
• 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

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 unzip 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
