Methods

closeEventsSubscription(String subscriptionId) → void
This method will close the subscription of the subscriptionId that you passed to it.
override
disconnectFromRelays({int closeCode(String relayUrl)?, String closeReason(String relayUrl)?, void onRelayDisconnect(String relayUrl, WebSocket relayWebSOcket, dynamic webSocketDisconnectionMessage)?}) Future<bool>
freeAllResources([bool throwOnFailure = false]) Future<bool>
override
init({required List<String> relaysUrl, void onRelayListening(String relayUrl, dynamic receivedData, WebSocket? relayWebSocket)?, void onRelayConnectionError(String relayUrl, Object? error, WebSocket? relayWebSocket)?, void onRelayConnectionDone(String relayUrl, WebSocket? relayWebSocket)?, bool lazyListeningToRelays = false, bool retryOnError = false, bool retryOnClose = false, bool ensureToClearRegistriesBeforeStarting = true, bool ignoreConnectionException = true, bool shouldReconnectToRelayOnNotice = false, Duration connectionTimeout = const Duration(seconds: 5)}) Future<void>
This method is responsible for initializing the connection to all relays. It takes a List<String> of relays urls, then it connects to each relay and registers it for future use, if relayUrl is empty, it will throw an AssertionError since it doesn't make sense to connect to an empty list of relays.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reconnectToRelays({required void onRelayListening(String relayUrl, dynamic receivedData, WebSocket? relayWebSocket)?, required void onRelayConnectionError(String relayUrl, Object? error, WebSocket? relayWebSocket)?, required void onRelayConnectionDone(String relayUrl, WebSocket? relayWebSocket)?, required bool retryOnError, required bool retryOnClose, required bool shouldReconnectToRelayOnNotice, required Duration connectionTimeout, required bool ignoreConnectionException, required bool lazyListeningToRelays, bool relayUnregistered = true}) Future<void>
override
relayInformationsDocumentNip11({required String relayUrl, bool throwExceptionIfExists = true}) Future<RelayInformations?>
Ths method will get you RelayInformations that contains the given relayUrl using the NIP11 implementation.
override
sendCountEventToRelays(NostrCountEvent countEvent, {required void onCountResponse(NostrCountResponse countResponse)}) → void
override
sendCountEventToRelaysAsync(NostrCountEvent countEvent, {required Duration timeout}) Future<NostrCountResponse>
override
sendEventToRelays(NostrEvent event, {void onOk(NostrEventOkCommand ok)?}) → void
This method is responsible for sending an event to all relays that you did registered with the init method.
override
sendEventToRelaysAsync(NostrEvent event, {required Duration timeout, void onOk(NostrEventOkCommand ok)?}) Future<NostrEventOkCommand>
This method is responsible for sending an event to all relays that you did registered with the init method, and gets you a Future of NostrEventOkCommand that will be triggered when the event is accepted by the relays.
override
startEventsSubscription({required NostrRequest request, void onEose(NostrRequestEoseCommand ease)?, bool useConsistentSubscriptionIdBasedOnRequestData = false}) NostrEventsStream
This method will send a request to all relays that you did registered with the init method, and gets your a Stream of NostrEvents that will be filtered by the request's subscriptionId automatically.
override
startEventsSubscriptionAsync({required NostrRequest request, required Duration timeout, void onEose(NostrRequestEoseCommand ease)?, bool useConsistentSubscriptionIdBasedOnRequestData = false, bool shouldThrowErrorOnTimeoutWithoutEose = true}) Future<List<NostrEvent>>
Retuens a Future of List<NostrEvent> that will be triggered when the onEose callback is triggered of the subscription created by your request.
override
startListeningToRelay({required String relay, required void onRelayListening(String relayUrl, dynamic receivedData, WebSocket? relayWebSocket)?, required void onRelayConnectionError(String relayUrl, Object? error, WebSocket? relayWebSocket)?, required void onRelayConnectionDone(String relayUrl, WebSocket? relayWebSocket)?, required bool retryOnError, required bool retryOnClose, required bool shouldReconnectToRelayOnNotice, required Duration connectionTimeout, required bool ignoreConnectionException, required bool lazyListeningToRelays, void onNoticeMessageFromRelay(String relay, WebSocket? relayWebSocket, NostrNotice notice)?}) → void
This method will start listening to all relays that you did registered with the init method.
override
toString() String
A string representation of this object.
