Get the Flutter SDK: Update your path

1. Determine the directory where you placed the Flutter SDK.
2. Open (or create) the rc file for your shell. For example, macOS Mojave (and earlier) uses the Bash shell by default, so edit $HOME/.bashrc. macOS Catalina uses the Z shell by default, so edit$HOME/.zshrc. If you are using a different shell, the file path and filename will be different on your machine.
3. Add the following line and change [PATH_TO_FLUTTER_GIT_DIRECTORY] to be the path where you cloned Flutter’s git repo: $export PATH="$PATH:[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin".
4. Run source $HOME/.<rc file> to refresh the current window, or open a new terminal window to automatically source the file. 5. Verify that the flutter/bin directory is now in your PATH by running:$ echo $PATH Verify that the flutter command is available by running:$ which flutter.
