Use local elinux artifacts without downloading from GitHub

Normally, this setting is not necessary!

Use alternative server for elinux engine artifacts

If you need to use your own artifact server instead of GitHub (pre-built images in flutter-embedded-linux repo), please use ELINUX_ENGINE_BASE_URL env.

The default URL is https://github.com/sony/flutter-embedded-linux/releases, but you can override it by using this environment var.

Use local artifact files on Host PC

This is basically for developer in China.

If you have a network connection issue when you download the artifacts, please try the following alternative way.

1. Download the corresponding artifacts from https://github.com/sony/flutter-embedded-linux/releases manually

• elinux-common.zip
• elinux-arm64-debug.zip
• elinux-arm64-profile.zip
• elinux-arm64-release.zip
• elinux-x64-debug.zip
• elinux-x64-profile.zip
• elinux-x64-release.zip

2. export ELINUX_ENGINE_BASE_LOCAL_DIRECTORY=<path_to_directory_of_downloaded_artifacts>
3. run flutter commands
