6 | # The Design Pattern
7 |
8 | 
9 |
10 | ## Goals for this sample
11 |
12 | - Shows a state management approach using the [Provider](https://pub.dev/packages/provider) package,mainly use StreamProvider and ChangeNotifier.
13 | - Show a logic for fetch data from different datasources as above graph.
14 |
15 | ## Memory fetch data
16 |
17 | Change `repositories/catalog.dart`
18 |
19 | ```
20 | const dataSource = 'memory';
21 | ```
22 |
23 | `repositories/catalog.dart` A route distribution for fetching data
24 | `memory/catalog.dart` All CURD operations will be here
25 | `file/catalog.dart` Define data
26 |
27 | ## Sqlite fetch data
28 |
29 | Change `repositories/catalog.dart`
30 |
31 | ```
32 | const dataSource = 'db';
33 | ```
34 |
35 | #### Notice
36 |
37 | You can't use `cart.items.contains(item)` to compare catalog whether exists in cart,because use database reload data.Add `contains` method in cart controller,and use below
38 |
39 | ```
40 | cart.contains(item.id)
41 | ```
42 |
43 | ## Todo
