This command is used to start the Metro bundler server for a React Native application on a specific port.
Here's a breakdown of the command:
react-native start: This is the command to start the Metro bundler server for the React Native application.--port: This is an option to specify the port number for the server to listen on.${3000}: This is a placeholder value for the port number. In this case, it is set to 3000.
So, when you run react-native start --port ${3000}, it will start the Metro bundler server and make it listen on port 3000.
