Re: [pve-devel] [PATCH dart_api_client 1/1] change exception toString to only print details if not null

["Michael Köppl" <m.koeppl@proxmox.com>]

Thanks for having a look at this. I did not encounter this in the app.
The places where I could have, avoid this by either printing `e.message`
directly or simply throwing. This patch was a reaction to [0], where
"Host unreachable, possibly offline. -> null" would have been printed if
the the error had been wrapped in a ProxmoxApiException. Of course you
could just throw and avoid this altogether, but I think consistently
wrapping errors in ProxmoxApiException makes sense if we wanted to make
changes to error messages in the future and still keep things
consistent. Also, since `details` is defined as `Map<String, dynamic>?`,
I figured it might as well be treated as possibly null as there are
cases where there are no details (e.g. authentication timeout).
