[pve-devel] [PATCH pve_flutter_frontend] main: add check to show welcome screen only when no server configured

[Aaron Lauterer <a.lauterer@proxmox.com>]

This additional check will make sure that people who have been using the
app already do not get to see the welcome screen.

In that situation we also want to make sure that we set the shared pref
for the welcome screen to the same state as if it has been seen.

I am still unsure if we shouldn't just show the welcome screen to
everyone at least once but that might annoy quite a lot of people though :/

So I prepared this patch should we decide against it.

It needs the following patches applied first [0]

The slightly weird formatting of the if clause is caused by the dart
auto formatter.
