showSyncServerSheet function
The sync-server picker (docs/specs/sync-server-picker.md §3.4, P3-13):
the servers the host OFFERS as rows (the one in use marked), "App default"
when the default is not among them, and a custom entry — a URL field, a
"Check server" step, a trust notice, then "Use this server". Every switch
is preceded by the in-flight notice (it restarts the sync pass in
progress; the balance and history stay), and a custom server by the trust
notice as well. Opened from the sync sheet's Server row.
Implementation
Future<void> showSyncServerSheet(BuildContext context) {
return showWalletSheet<void>(
context,
builder: (_) => const SyncServerSheet(),
);
}
