How it works...

There’s not much to explain here: we simply used constants instead of repeating the name of the keys for our JSON data.

If you come from Android development, you’ll find this pattern rather familiar. Using constants instead of hard typing in the field names is usually a great idea and helps prevent errors that are difficult to debug.

One note about the style: in other languages, such as Java, you usually name your constants in SCREAMING_CAPS. In our code, for example, the first constant would be called KEY_ID. In Dart and Flutter, the recommendation is to use lowerCamelCase for constants.
