fix: Is there any way of improving "init" speeds for instant app startups?

[FL0D3V]

Description

Currently i execute the init method of the OidcUserMananger in an FutureBuilder in the startup of the app and i show a loading indicator till it is finished, then i show the first page.
I don't know if this is a problem or not but this method needs about 3 seconds on every start of the app.
I need to be sure that anything is checked and initialized before starting the app and the user is logged in to show the homepage.
Is there a way to speed this up, so that the app can feel more like f.e. Instagram or similar apps with instant startup times?
I don't know how these apps handle auth checks but it would be nice to support instant startup times.

@FL0D3V can you please show me the initialization logic? it should never take 3 seconds to send 3 requests

The big problem is that you have to init with api calls to use the user state. If the user has a bad connection it will take many seconds to start and be able to use the app. I basically wrapped the app builder with a futurebuilder and i show a loading indicator while the manager initializes.
