QR Scanner App

A Flutter project for QR code scanner

About

The application includes two screens: Welcome and Scanner.

The app is built using the new template: Skeleton.

State management

Using Bloc/RxDart to manage states.

I use an AppStateBloc to manage the state of the application:

• authorized
• unAuthorized
• loading

Shared Preferences

Use the SharedPreferences plugin to save application states and QR codes and caches.

The next time you open the app, the app status and the QR codes will be reloaded.
