How to use 'web_socket_channel' in todos_repository_simple

Web socket as data Provider

---

todos_repository_simple explains nicely about the benefits of using repository as singleton. But no where it's mentioned how to handle the web sockets.

How can I use web socket (webSocket and fileStorage) instead of rest (webClient and fileStorage) ?

Some key points between web socket and rest.

• The name itself signify socket is stateLess and rest is stateFull
• socket is bidirectional : Server can send data to client and client will have a callback to perform accordingly and vice versa.

My dataProvider is socket and fileStorage and follows flutter_bloc architecture.

Every time we receive data from socket :
Article : reload the UI directly in widget by mapping switch case.
Flutter_bloc: need to reload the UI through bloc_state.

Thanks.

Here is an example of using Aqueduct server and a dart client to implement a chat room using sockets:

Can probably adapt this to the todos_repository_simple or your app.
Plus you have dart on both the client and server sides and aqueduct is easy enough to deploy.
