Development

Compiling the Flutter engine for a new platform requires an exorbitant amount of disk space.

Dependencies

• .envrc, i.e. direnv
• sudo apt-get install build-essential

Note: In GitHub Codespaces:

1. Install Linux Brew
2. brew install direnv
3. Ensure the Brew and direnv shell hooks are installed, i.e. added to ~/.bashrc:

eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"
eval "$(direnv hook bash)"

Compiling Flutter Engine

1. Install depot_tools

   For best results, cp example.envrc .envrc and ensure depo_tools is added to the path.

2. Download Flutter engine sources, assuming depot_tools is available on the path:

• fetch flutter
• git -C src/flutter remote rename origin upstream
• gclient sync
