14 | ## Why use mobync
15 |
16 | Mobync is a synchronization library aimed to facilitate online-offline sync between multiple devices for any frontend, any backend, and any database.
17 |
18 | This repository implements the Mobync client library in Flutter, which means you can start using Mobync sync on your client regardless of which backend you might be using or even which database.
19 |
20 | As Mobync aims to provide online-offline sync between client and server, you will need to use the mobync library both on your frontend application and backend.
21 |
22 | Currently, Mobync has a Dart client implementation and a Python server implementation. That means you can plug Mobync on your Flutter app and provide online-offline synchronization.
23 |
24 | ### Online-offline synchronization
25 |
26 | Online-offline synchronization means that your app will work seamlessly both online and offline, the user can use without noticing any difference, and you can implement your app not worrying about this when using Mobync.
27 |
28 | Mobync will automatically make your app store your changes locally on your app's database when the user has no connection, and automatically sync the data to the backend when the user has internet.
29 |
30 | ### Multiple devices support
31 |
32 | Your user can use your service across multiple devices at the same time and all will have their data synchronized with Mobync.
33 |
34 | Mobync implements a protocol that merges the user data and resolves conflicts.
35 |
36 | Mobync's protocol allows mobile applications running on distributed clients to get synced to a single source of truth to manage users’ data using any storage type. Mobync users Dart and Flutter to implement this protocol and communicate to a web server written in Python.
37 |
38 | ## Example projects
39 |
40 | You can see some example projects using mobync on [Examples](https://github.com/mobync/flutter-client/blob/master/example).
41 |
42 |
43 | ## Mobync Flutter Client Package
44 |
45 | Using Mobync, you will wrap your database operations in such a way that any local data will get synced to a remote server, what will allow users from multiple clients to have an offline-online experience.
46 |
47 | ## Common usage
48 | ```dart
49 | MyMobyncClient client = MyMobyncClient.instance;
50 |
51 | /// Create an instance.
52 | final obj1 = {'id': 'uuid1', 'field1': 'a', 'field2': 'b'};
53 | MobyncResponse res1 = await client.create('model1', obj1);
54 |
55 | /// Update an instance.
56 | final obj = {'id': 'uuid1', 'field1': 'x'};
57 | MobyncResponse res = await client.update('model1', obj);
58 |
59 | /// Delete an instance.
60 | MobyncResponse res = await client.delete('model1', 'uuid1');
61 |
62 | /// Synchronize.
63 | await client.synchronize();
64 |
65 | /// Read from model.
66 | MobyncResponse res = await client.read('model1');
67 | /// Access data read.
68 | if(res.success)
69 | print(res.data);
70 | ```
71 |
72 | You might implement the ```MobyncClient``` abstract class. At this moment we do not support any migration system so it is up to the developer to use one from his preferences. Despite of that, the developer still have to implement the library-specific models.
73 |
74 | On the following snippet you can check out a Mobync implementation using SQLite on the client storage.
75 |
76 | ```dart
77 | import 'package:mobync/mobync.dart';
78 | import 'package:mobync/constants/constants.dart';
79 | import 'package:mobync/models/models.dart';
80 | import 'package:sqflite/sqflite.dart';
81 | import 'package:example/myModel.dart';

83 | class MyMobyncClient extends MobyncClient {
84 | MyMobyncClient._privateConstructor();
85 | static final MyMobyncClient instance = MyMobyncClient._privateConstructor();
