# How Scope Works

### How it works

Scope uses Dart's native [Zone](https://api.dart.dev/stable/2.15.1/dart-async/Zone-class.html) implementation.

Zones allow you to associate a `map` of key/value pairs with each zone.

Scope takes advantage of that fact and wraps lots of syntactic sugar around the Zone to make it easy to use.
