blop 0.0.2+1

Package that based on bloc and provide simplified flow to define process and manage state

blop

Business Logic Process

Reimagination of BLOC architecture with main goal to decrease code size and add ability to detect while complicated process is end.

Install

add to pubspec.yaml

dependencies:
    blop: any

dev_dependencies:
    blop_generator: any

Usage

For create processor just extends SimpleBlop<State> or Blop<Event,State> if you need the ability to extend event. All method calls add to queue and process in it's order like event in bloc All methods return Future<State>

Ex. we can define processor to control user state

@blopProcessor
class UserProcessor extends SimpleBlop<UserModel>{
    // method can has name
    @BlopProcess(name: "logout")
    UserModel exit() => UserModel.unauthorized();

    // if name is not specified that get from function name without first underscore
    @blopProcess
    Stream<UserModel> _login(String phone,String pass) async * {
        yield UserModel.unauthorized(); // remove old user data
        // fetch data from network
        yield UserNetwork.login(phone,pass);
    }
}

// ... somewhere in code
// this code await method. If error hapens it's throw that error
final user = await context.read<UserProcessor>().login('phone','pass');

TODO add to readme

• basic usage
• Event transform
• Method complete strategy
  • cancel with data
  • cancel with error
  • cancel on close
• Method different return types
• Await method
• mapEventToState override (based on remote_value)
