Refractor the confapp to follow MVVM architecture and use Riverpod instead of BLOC

[quekyj]

Motivation

The architecture of BLOC is too complicated for confapp. It not that user friendly compared to Provider pattern (Model-View-ViewModel) pattern.

Desired solution

Refractor the state management to Riverpod Provider and Riverpod Generator. We can use MVVM structure as below:

/lib/src:
    - constant/
    - module/
        -  ui/
        - model/
        - view/
        - services/
        - provider/

The pattern above is cleaner and easier to maintain compared to cubit and BLOC.

Alternatives considered

We can just use back BLOC.
