flutter bloc pattern

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 bloc 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)
