UConnectivity class - utilities library

Properties

hashCode → int: The hash code for this object.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
inherited

isCellular → bool: Same as UNetwork.isCellular.
no setter
isEthernet → bool: Same as UNetwork.isEthernet.
no setter
isMetered → bool: Same as UNetwork.isMetered.
no setter
isOffline → bool: Same as UNetwork.isOffline.
no setter
isOnline → bool: Same as UNetwork.isOnline.
no setter
isVpn → bool: Same as UNetwork.isVpn.
no setter
isWifi → bool: Same as UNetwork.isWifi.
no setter
listenable → ValueListenable<UNetworkStatus>: For ValueListenableBuilder / AnimatedBuilder.
no setter
offlineGrace ↔ Duration: How long "offline" must persist before it is reported. Zero reports every blip.
getter/setter pair
onlineStream → Stream<bool>: Emits only when online ↔ offline flips.
no setter
probeCacheDuration ↔ Duration: How long a hasInternet answer is reused.
getter/setter pair
probeUrls ↔ List<Uri>?: Checked by hasInternet, first answer wins. Put your own API first: it is the one host that matters, and it is reachable on networks that filter public probes. Defaults to U.baseUrl followed by two public 204 endpoints.
getter/setter pair
status → UNetworkStatus: Current state, updated live. Before init completes it reads as online.
no setter
stream → Stream<UNetworkStatus>: Every change of status.
no setter

addresses({bool includeLoopback = false}) → Future<List<UNetworkAddress>>: This device's IP addresses (empty on the web). Loopback is skipped unless includeLoopback.
dispose() → Future<void>: Stops listening (tests, or an app that never needs network state again).
hasInternet({bool force = false, Duration timeout = const Duration(seconds: 5)}) → Future<bool>: Whether the internet (by default: your own API) actually answers. Any HTTP response counts, since a 401 still proves the round trip works. Cached for probeCacheDuration.
init() → Future<void>: Starts listening. Idempotent; initU() calls it for you.
listen(void onChange(UNetworkStatus status)) → StreamSubscription<UNetworkStatus>: Same as UNetwork.listen.
localIp() → Future<String?>: The first non-loopback IPv4 address (the one other devices on the LAN would use).
refresh() → Future<UNetworkStatus>: Asks the OS again right now, skipping offlineGrace.
whenOnline({Duration? timeout}) → Future<void>: Completes as soon as the device is online (immediately if it already is). Throws TimeoutException after timeout, when given.
