One final item we need to cover before diving into building apps is the concept of channels. Flutter segments its development streams into channels, which is really just a fancy name for Git branches. Each channel represents a different level of stability for the Flutter framework. Flutter developers will release the latest features to the master channel first. As these features stabilize, they will first get promoted to the dev channel, then to beta, and finally to the stable channel.

In your terminal window, type in the following command:

You'll probably see output that looks like this:
