Why Brick?

• Out-of-the-box offline access to data
• Handle and hide complex serialization/deserialization logic
• Single access point and opinionated DSL
• Automatic, intelligently-generated migrations
• Legible querying interface

What is Brick?

Brick is an extensible query interface for Dart applications. It's an all-in-one solution responsible for representing business data in the application, regardless of where your data comes from. Using Brick, developers can focus on implementing the application, without concern for where the data lives. Brick was inspired by the need for applications to work offline first, even if an API represents your source of truth.

Quick Start

1. Add the packages:

   dependencies:
     brick_offline_first: any
   dev_dependencies:
     brick_offline_first_with_rest_build:
       git:
         url: https://github.com/greenbits/brick.git
         path: packages/brick_offline_first_with_rest_build
     build_runner: any
   

2. Configure your app directory structure to match Brick's expectations:

   mkdir -p lib/app/adapters lib/app/db lib/app/models;
   

3. Add models that contain your app logic. Models must be saved in lib/app/models/<class_as_snake_name>.dart.
4. Run flutter pub run build_runner run to generate your models (or pub run build_runner run if you're not using Flutter) and sometimes migrations. Rerun after every new model change or flutter pub run build_runner watch for automatic generations.
5. Extend an existing repository or create your own:

   // lib/app/repository.dart
   import 'package:brick_offline_first/offline_first_with_rest.dart';
   import 'package:audio_journal/app/brick.g.dart';
   export 'package:brick_offline_first/offline_first_with_rest.dart' show And, Or, Query, QueryAction, Where, WherePhrase;
   
   class Repository extends OfflineFirstWithRestRepository {
     Repository()
         : super(
             migrations: migrations,
             restProvider: RestProvider(
               'http://localhost:3000',
               modelDictionary: restModelDictionary,
             ),
             sqliteProvider: SqliteProvider(
               _DB_NAME,
               modelDictionary: sqliteModelDictionary,
             ),
           );
   }
   

6. Profit.
