Flutter Chat

This is a simple chat app written in Flutter with Firestore backend. It was inspired by this dribbble shot.

It was created during Flutter Warsaw and devWarsztaty workshop #2 on April 13, 2019.

It contains already prepared google-services.json and GoogleService-Info.plist files, but they will stop working soon in the future, so you may need to recreate them in your own Firebase console by following this guide.

Getting Started

This project uses Firebase and Firestore to work.

Please run flutter upgrade before. The project was developed with Flutter 1.3.8 initially.

Prepare Firestore database

Before starting you should have prepared your Firestore database as follows:

1. Add collection rooms
2. In rooms add new document with auto id and following fields:

• name : string
• lastMessage : map
  • avatar : string
  • from : string
  • content : string
  • id : string
  • timestamp : timestamp

3. Initially set all the security rules as public. Remember to turn them off later to protect your account quota.

Part 1

At this point you have a simple one page app with Firebase and other small details preconfigured like file structure or required packages and plugins.

In this part we're going to write a basic login page login_page.dart, chat_rooms_page.dart and initial layout of messages_page.dart.

Part 2

In this part we're goting to develop models for storing chat rooms and messages across the app in:

• chat_room.dart
• chat_rooms_model.dart
• message.dart
• messages_model.dart

We're going to use Scoped Model to update views after fetching from or uploading data to Firestore.
