InternetChecker class
Performs real internet reachability checks via DNS lookup.
This is more reliable than connectivity_plus alone, which only checks
if a network interface is available — not whether the internet is
actually reachable (e.g. captive portal, firewall, DNS failure).
final checker = InternetChecker();
// One-shot check
final isOnline = await checker.hasInternetAccess();
// Periodic stream
checker.startPeriodicCheck();
checker.statusStream.listen((isOnline) {
print('Internet: $isOnline');
});
