Official Documents: Using the FlutterFire CLI

# Install the CLI if not already done so
dart pub global activate flutterfire_cli    // Successfully installed 

# Run the `configure` command, select a Firebase project and platforms
flutterfire configure.   

But while running next command for configure I'm getting a following error.

flutterfire configure        
zsh: command not found: flutterfire

Some of my search results for solution:

Actually I ignored warning while installing

Warning: Pub installs executables into $HOME/.pub-cache/bin, which is not on your path.
You can fix that by adding this to your shell's config file (.bashrc, .bash_profile, etc.):

export PATH="$PATH":"$HOME/.pub-cache/bin"

Activated flutterfire_cli 0.2.6+1.
