Flutter define variable

The basic building block of information in your Dart program will be variables. Anytime you’re working with data in an app, you can store that data in variables. For example, if you’re building a chat application, you can use variables to refer to chat messages or a user. Variables store references to these values.

This is done with this code snippet:
