web_socket_client is just a wrapper for web_socket_channel, with only 15 commits which is not stable yet.
Current version is dev: 0.1.0-dev.3
I think its better to grab idea from it and implement it our own.
btw, how is it better? do we have a metric or comparison for its advantages over our current implementation?

As you said web_socket_client is a wrapper for web_socket_channel so all core functionalities of web_socket_channel is available.
Developer of this package is Felix Angelov and I checked the source code and the code quality is very good, and since Angelov is a well-known developer in the community, the package will be supported for sure. In the long term it has more benefits compared to developing a package by ourselves.
This package has 2 key features that could help us, first of all Reconnecting timer that allows making reconnect process automated, and the other one is Monitoring the Connection that gives us a stream of connection status and terminates dependency to connectivity_plus that is a package that has a lot of issues in different platforms.

if I want to summarize the benefits here they are:

1. Package is written by the Bloc developer
2. Reconnecting is supported
3. Monitoring the Connection is supported
4. Remove the connectivity_plus dependency
5. No need to ping the server manually (this is not related to the new package, just a refactor)
6. The source of truth for connectivity is only WS itself
7. Reduce the complexity of the connection bloc

What about LinearBackoff ? Is it supported?

[hamed-rezaee]

we are looking for a way to connect asap, so I suppose ConstantBackoff is better in our case.

[ramin-deriv]

ws.BinaryExponentialBackoff is the one should be used to avoid flooding the server.

[abedelaziz-deriv]

I wouldn't use any dev packages. Especially with open bugs like this one.

@abedelaziz-deriv this is just a POC.
