The project is maintained by a non-profit organisation, along with an amazing collections of Flutter samples. We're trying to make continuous commits for changes along with the Flutter tech progress.

Design Pattern

Goals for this sample

  • Shows a state management approach using the Provider package,mainly use StreamProvider and ChangeNotifier.
  • Show a logic for fetch data from different datasources as above graph.

Memory fetch data

Change repositories/catalog.dart

const dataSource = 'memory';

repositories/catalog.dart A route distribution for fetching data
memory/catalog.dart All CURD operations will be here
file/catalog.dart Define data

Sqlite fetch data

Change repositories/catalog.dart

const dataSource = 'db';

Notice

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

cart.contains(item.id)

Todo

  • Http implement
