Builder/Cubit for combining multiple GET requests on one page.

[piotruela]

In my project I have several pages on which I need to perform more that 1 different requests in order to get all the sections that are displayed.
I'd like to have a Builder which will be capable of handling multiple BaseRequestCubits and combine their states into something like:

• If all 3 are in "Loading state" -> Show just one loading indicator on page,
• If at least one have the data -> Display it on the page and show other sections with separate loaders,
• If all three requests failed -> Show just one error state,
  ...
