firebase - Get all from a Firestore collection in Flutter

Question

I set up Firestore in my project. I created new collection named categories. In this collection I created three documents with uniq id. Now I want to get this collection in my Flutter application so I created CollectionReference:

Firestore.instance.collection('categories')

but I don't know what next.

I am using this plugin firebase_firestore: 0.0.1+1
