51 | Flyer Chat is a platform for creating in-app chat experiences using Flutter or [React Native](https://github.com/flyerhq/react-native-firebase-chat-core). This repository contains Firebase BaaS implementation for Flutter. We are also working on our more advanced SaaS and self-hosted solutions.
52 |
53 | * **Free, open-source and community-driven**. We offer no paid plugins and strive to create an easy-to-use, almost drop-in chat experience for any application. Contributions are more than welcome! Please read our [Contributing Guide](CONTRIBUTING.md).
54 |
55 | * **Chat UI agnostic**. You can choose the chat UI you prefer. But if you don't have one, we provide our own free and open-source [Flutter Chat UI](https://pub.dev/packages/flutter_chat_ui), which can be used to create a working chat in minutes.
56 |
57 | * **Easy to use**. Returns streams of data for messages, rooms and users. [Firebase Security Rules](https://firebase.google.com/docs/rules) control access to the data. Check our [documentation](https://docs.flyer.chat/flutter/firebase/firebase-overview) for the info.
58 |
59 | ## Getting Started
60 |
61 | ### Requirements
62 |
63 | `Dart >=2.19.0` and `Flutter >=3.0.0`, [Firebase](https://firebase.google.com) project.
64 |
65 | Read our [documentation](https://docs.flyer.chat/flutter/firebase/firebase-overview) or see the [example](https://github.com/flyerhq/flutter_firebase_chat_core/tree/main/example) project. To run the example project you need to have your own [Firebase](https://firebase.google.com) project and then follow steps 1 and 2 of [Add Firebase to your Flutter app](https://firebase.google.com/docs/flutter/setup), override `firebase_options.dart`, don't commit it though 😉
66 |
67 | After all of this is done you will need to register a couple of users and the example app will automatically suggest email and password on the register screen, default password is `Qawsed1-`. To set up [Firebase Security Rules](https://firebase.google.com/docs/rules) so users can see only the data they should see, continue with our [documentation](https://docs.flyer.chat/flutter/firebase/firebase-rules).

1 | # Contributor Covenant Code of Conduct
2 |
3 | ## Our Pledge
4 |
5 | We as members, contributors, and leaders pledge to make participation in our
6 | community a harassment-free experience for everyone, regardless of age, body
7 | size, visible or invisible disability, ethnicity, sex characteristics, gender
8 | identity and expression, level of experience, education, socio-economic status,
9 | nationality, personal appearance, race, caste, color, religion, or sexual identity
10 | and orientation.
11 |
12 | We pledge to act and interact in ways that contribute to an open, welcoming,
13 | diverse, inclusive, and healthy community.
14 |
15 | ## Our Standards
16 |
17 | Examples of behavior that contributes to a positive environment for our
18 | community include:
19 |
20 | * Demonstrating empathy and kindness toward other people
21 | * Being respectful of differing opinions, viewpoints, and experiences
22 | * Giving and gracefully accepting constructive feedback
23 | * Accepting responsibility and apologizing to those affected by our mistakes,
24 | and learning from the experience
25 | * Focusing on what is best not just for us as individuals, but for the
26 | overall community

28 | Examples of unacceptable behavior include:
29 |
30 | * The use of sexualized language or imagery, and sexual attention or
31 | advances of any kind
32 | * Trolling, insulting or derogatory comments, and personal or political attacks
33 | * Public or private harassment
34 | * Publishing others' private information, such as a physical or email
35 | address, without their explicit permission
36 | * Other conduct which could reasonably be considered inappropriate in a
37 | professional setting
38 |
39 | ## Enforcement Responsibilities
40 |
41 | Community leaders are responsible for clarifying and enforcing our standards of
42 | acceptable behavior and will take appropriate and fair corrective action in
43 | response to any behavior that they deem inappropriate, threatening, offensive,
44 | or harmful.
45 |
46 | Community leaders have the right and responsibility to remove, edit, or reject
47 | comments, commits, code, wiki edits, issues, and other contributions that are
48 | not aligned to this Code of Conduct, and will communicate reasons for moderation
49 | decisions when appropriate.
50 |
51 | ## Scope
52 |
53 | This Code of Conduct applies within all community spaces, and also applies when
54 | an individual is officially representing the community in public spaces.
55 | Examples of representing our community include using an official e-mail address,
56 | posting via an official social media account, or acting as an appointed
57 | representative at an online or offline event.
58 |
59 | ## Enforcement
60 |
61 | Instances of abusive, harassing, or otherwise unacceptable behavior may be
62 | reported to the community leaders responsible for enforcement at .
63 | All complaints will be reviewed and investigated promptly and fairly.
64 |
65 | All community leaders are obligated to respect the privacy and security of the
66 | reporter of any incident.
67 |
68 | ## Enforcement Guidelines
69 |
70 | Community leaders will follow these Community Impact Guidelines in determining
71 | the consequences for any action they deem in violation of this Code of Conduct:
72 |
73 | ### 1. Correction
74 |
75 | **Community Impact**: Use of inappropriate language or other behavior deemed
76 | unprofessional or unwelcome in the community.
77 |
78 | **Consequence**: A private, written warning from community leaders, providing
79 | clarity around the nature of the violation and an explanation of why the
80 | behavior was inappropriate. A public apology may be requested.
81 |
82 | ### 2. Warning
83 |
84 | **Community Impact**: A violation through a single incident or series
85 | of actions.
86 |
87 | **Consequence**: A warning with consequences for continued behavior. No
88 | interaction with the people involved, including unsolicited interaction with
89 | those enforcing the Code of Conduct, for a specified period of time. This
90 | includes avoiding interactions in community spaces as well as external channels
91 | like social media. Violating these terms may lead to a temporary or
92 | permanent ban.
93 |
94 | ### 3. Temporary Ban
95 |
96 | **Community Impact**: A serious violation of community standards, including
97 | sustained inappropriate behavior.
98 |
99 | **Consequence**: A temporary ban from any sort of interaction or public
100 | communication with the community for a specified period of time. No public or
101 | private interaction with the people involved, including unsolicited interaction
102 | with those enforcing the Code of Conduct, is allowed during this period.
103 | Violating these terms may lead to a permanent ban.
104 |
105 | ### 4. Permanent Ban
106 |
107 | **Community Impact**: Demonstrating a pattern of violation of community
108 | standards, including sustained inappropriate behavior, harassment of an
109 | individual, or aggression toward or disparagement of classes of individuals.

3 | title: Usage
4 | ---
5 |
6 | As mentioned in [How it works?](firebase-overview#how-it-works), you will need to register a user using [Firebase Authentication](https://firebase.google.com/docs/auth). If you are using Firebase Authentication as your auth provider you don't need to do anything except calling `FirebaseChatCore.instance.createUserInFirestore` after registration.
7 |
8 | ```dart
9 | import 'package:flutter_chat_types/flutter_chat_types.dart' as types;
10 | import 'package:flutter_firebase_chat_core/flutter_firebase_chat_core.dart';
11 |
12 | await FirebaseChatCore.instance.createUserInFirestore(
13 | types.User(
14 | firstName: 'John',
15 | id: credential.user!.uid, // UID from Firebase Authentication
16 | imageUrl: 'https://i.pravatar.cc/300',
17 | lastName: 'Doe',
18 | ),
19 | );
20 | ```
21 |
22 | You can provide values like `firstName`, `imageUrl` and `lastName` if you're planning to have a screen with all users available for chat. The `id` is the only required field and you **need to** use the `uid` you get from the Firebase Authentication after you register a user. If you don't use Firebase for authentication, you can register a user using your custom `JWT` token, then call `FirebaseChatCore.instance.createUserInFirestore` as described above.
23 |
24 | Aside from registration, you will need to log users in when appropriate, using available methods from Firebase Authentication, including the custom `JWT` token.
25 |
26 | ## Firebase Chat with custom backend
27 |
28 | This wasn't verified on production, but if you have your backend and want to use Firebase only for the chat functionality, you can register/login users using custom `JWT` token as described above and save received `uid` to your `users` table. Then you can have a screen with all users from your `users` table where each of them will have an assigned `uid` that will be used to start a chat. Or maybe you will have a search mechanism implemented on your backend, or you don't show users at all, just a button to start a chat with a random person, you still have access to that `uid`.
29 |
30 | Alternatively, you can use the `FirebaseChatCore.instance.users()` stream which will return all registered users with avatars and names.
31 |
32 | ```dart
33 | import 'package:flutter/material.dart';
34 | import 'package:flutter_chat_types/flutter_chat_types.dart' as types;
35 | import 'package:flutter_firebase_chat_core/flutter_firebase_chat_core.dart';
36 |
37 | class UsersPage extends StatelessWidget {
38 | const UsersPage({Key? key}) : super(key: key);
39 |
40 | @override
41 | Widget build(BuildContext context) {
42 | return Scaffold(
43 | body: StreamBuilder>(
44 | stream: FirebaseChatCore.instance.users(),
45 | initialData: const [],
46 | builder: (context, snapshot) {
47 | // ...
48 | },
49 | ),
50 | );
51 | }
52 | }
53 | ```
54 |
55 | ## Starting a chat
56 |
57 | When you have access to that `uid` or you have the whole `User` class from the `FirebaseChatCore.instance.users()` stream, you can call either `createRoom` or `createGroupRoom`. For the group, you will need to additionally provide a name and an optional image.
58 |
59 | ```dart
60 | import 'package:flutter/material.dart';
61 | import 'package:flutter_chat_types/flutter_chat_types.dart' as types;
62 | import 'package:flutter_firebase_chat_core/flutter_firebase_chat_core.dart';
63 |
64 | class UsersPage extends StatelessWidget {
65 | const UsersPage({Key? key}) : super(key: key);
66 |
67 | // Create a user with an ID of UID if you don't use `FirebaseChatCore.instance.users()` stream
68 | void _handlePressed(types.User otherUser, BuildContext context) async {
69 | final room = await FirebaseChatCore.instance.createRoom(otherUser);
70 |
71 | // Navigate to the Chat screen
72 | }
73 |
74 | @override
75 | Widget build(BuildContext context) {
76 | return Scaffold(
77 | body: StreamBuilder>(
78 | stream: FirebaseChatCore.instance.users(),
79 | initialData: const [],
80 | builder: (context, snapshot) {
81 | // ...
82 | },
83 | ),
84 | );
85 | }
86 | }
87 | ```
88 |
89 | ## Rooms
90 |
91 | To render user's rooms you use the `FirebaseChatCore.instance.rooms()` stream. `Room` class will have the name and image URL taken either from provided ones for the group or set to the other person's image URL and name. See [Security Rules](firebase-rules) for more info about rooms filtering.
92 |
93 | ```dart
94 | import 'package:flutter/material.dart';
95 | import 'package:flutter_chat_types/flutter_chat_types.dart' as types;
96 | import 'package:flutter_firebase_chat_core/flutter_firebase_chat_core.dart';
97 |
98 | class RoomsPage extends StatelessWidget {
99 | const RoomsPage({Key? key}) : super(key: key);
100 |
101 | @override
102 | Widget build(BuildContext context) {
103 | return Scaffold(
104 | body: StreamBuilder>(
105 | stream: FirebaseChatCore.instance.rooms(),
106 | initialData: const [],
107 | builder: (context, snapshot) {
108 | // ...
109 | },
110 | ),
111 | );
112 | }
113 | }
114 | ```
115 |
116 | ## Messages
117 |
118 | `FirebaseChatCore.instance.messages` stream will give you access to all messages in the specified room. If you want to have dynamic updates for the room itself, you will need to wrap messages stream with a room stream. See the [example](https://github.com/flyerhq/flutter_firebase_chat_core/blob/main/example/lib/chat.dart).
119 |
120 | ```dart
121 | import 'package:flutter/material.dart';
122 | import 'package:flutter_chat_types/flutter_chat_types.dart' as types;
123 | import 'package:flutter_firebase_chat_core/flutter_firebase_chat_core.dart';
124 |
125 | class ChatPage extends StatelessWidget {
126 | const ChatPage({Key? key}) : super(key: key);
127 |
128 | @override
129 | Widget build(BuildContext context) {
130 | return Scaffold(
131 | body: StreamBuilder>(
132 | initialData: const [],
133 | stream: FirebaseChatCore.instance.messages(widget.room),
134 | builder: (context, snapshot) {
135 | // ...
136 | },
137 | ),
138 | );
139 | }
140 | }
141 | ```
142 |
143 | If you use Flyer Chat UI you can just pass `snapshot.data ?? []` to the `messages` parameter of the Chat widget. See the [example](https://github.com/flyerhq/flutter_firebase_chat_core/blob/main/example/lib/chat.dart).
144 |
145 | ### Send a message
146 |
147 | To send a message use `FirebaseChatCore.instance.sendMessage`, it accepts 2 parameters:
148 |
149 | * Any partial message. Click [here](/chat-ui/types) to learn more about the types or check the [API reference](https://pub.dev/documentation/flutter_chat_types/latest/index.html). You provide a partial message because Firebase will set fields like `authorId`, `createdAt` and `id` automatically.
150 | * Room ID.
151 |
152 | ### Update the message
153 |
154 | To update the message use `FirebaseChatCore.instance.updateMessage`, it accepts 2 parameters:
155 |
156 | * Any message. Click [here](/chat-ui/types) to learn more about the types or check the [API reference](https://pub.dev/documentation/flutter_chat_types/latest/index.html). Use a message you get from the `FirebaseChatCore.instance.messages` stream, update it and send as this parameter.
157 | * Room ID.
158 |
159 | ## `firebaseUser`
160 |
161 | `FirebaseChatCore.instance.firebaseUser` is a shortcut you can use to see which user is currently logged in through Firebase Authentication. The returned type comes from the Firebase library and **it is not the same `User` as from the `flutter_chat_types` package**.
162 |
163 | :::note
164 |
165 | `firebaseUser` will not be updated dynamically, if you are looking for that feature, use `FirebaseAuth.instance.authStateChanges()` from the [Authentication](https://firebase.flutter.dev/docs/auth/overview) plugin.
