The default is 0 which disables the keep alive mechanism.
To enable the keep alive mechanism set this to a value greater than 0.
getter/setter pairinherited
- maxConnectionAttempts → int

final
- onAutoReconnect ↔ AutoReconnectCallback?
-
Auto reconnect callback, if auto reconnect is selected this callback will
be called before auto reconnect processing is invoked to allow the user to
perform any pre auto reconnect actions.
getter/setter pairinherited
- onAutoReconnected ↔ AutoReconnectCompleteCallback?
-
Auto reconnected callback, if auto reconnect is selected this callback will
be called after auto reconnect processing is completed to allow the user to
perform any post auto reconnect actions.

This will not be called even if set if [autoReconnect} is set,instead
AutoReconnectCallback will be called.
getter/setter pairinherited
- onFailedConnectionAttempt ↔ FailedConnectionAttemptCallback?
-
Failed Connection attempt callback.
Called on every failed connection attempt, if maxConnectionAttempts is
set to 5 say this will be called 5 times if the connection fails,
one for every failed attempt. Note this is never called
if autoReconnect is set.
If autoReconnect is set, the MqttNoConnectionException
is not raised if this callback is supplied.

getter/setter pairinherited
- resubscribeOnAutoReconnect ↔ bool

Re subscribe on auto reconnect.
Auto reconnect will perform automatic re subscription of existing confirmed subscriptions
unless this is set to false.
In this case the caller must perform their own re subscriptions manually using
unsubscribe
, subscribe and resubscribe as needed from the appropriate callbacks.getter/setter pairinherited - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- secure ↔ bool
-
If set use a secure connection, note TCP only, do not use for
secure websockets(wss).
getter/setter pair
- securityContext ↔ SecurityContext
-
The security context for secure usage
getter/setter pair
- server ↔ String
-
Server name
getter/setter pairinherited
-
socketOptions
↔ List<
RawSocketOption> -
The client supports the setting of both integer and boolean raw socket options
as supported by the Dart IO library RawSocketOption class.
Please consult the documentation for the above class before using this.
getter/setter pair
- subscriptionsManager ↔ MqttSubscriptionManager?
-
The subscriptions manager responsible for tracking subscriptions.
getter/setter pairinherited
-
updates
→ Stream<
List< MqttReceivedMessage< >MqttMessage> > -
The stream on which all subscribed topic updates are published to
no setterinherited
- useAlternateWebSocketImplementation ↔ bool
-
If set use the alternate websocket implementation
getter/setter pair
- useWebSocket ↔ bool
-
If set use a websocket connection, otherwise use the default TCP one
getter/setter pair
-
websocketProtocols
← List<
String> -
User definable websocket protocols. Use this for non default websocket
protocols only if your broker needs this. There are two defaults in
MqttWsConnection class, the single protocol is the default. Some brokers
will not accept a list and only expect a single protocol identifier,
in this case use the single protocol default. You can supply your own
list, or to disable this entirely set the protocols to an
empty list , i.e [].

Methods
-
checkCredentials(
String? username, String? password) → void -
Check the username and password validity
inherited
-
connect(
[String? username, String? password]) → Future< MqttConnectionStatus?> -
Performs a connect to the message broker with an optional
username and password for the purposes of authentication.
If a username and password are supplied these will override
any previously set in a supplied connection message so if you
supply your own connection message and use the authenticateAs method to
set these parameters do not set them again here.
override
-
disconnect(
) → void -
Disconnect from the broker.
inherited
-
disconnectOnNoPingResponse(
DisconnectOnNoPingResponse event) → void -
Called when the keep alive mechanism has determined that
a ping response expected from the broker has not arrived in the
time period specified by disconnectOnNoResponsePeriod.
inherited
-
doAutoReconnect(
{bool force = false}) → void -
Auto reconnect method, used to invoke a manual auto reconnect sequence.
If autoReconnect is not set this method does nothing.
If the client is not disconnected this method will have no effect
unless the
force
parameter is set to true, otherwise auto reconnect will try indefinitely to reconnect to the broker.inherited -
getConnectMessage(
String? username, String? password) → MqttConnectMessage -
Gets a pre-configured connect message if one has not been
supplied by the user.
Returns an MqttConnectMessage that can be used to connect to a
message broker if the user has not set one.
inherited
-
getSubscriptionStatus(
MqttSubscription subscription) → MqttSubscriptionStatus -
Gets the current status of a subscription.
inherited
-
getSubscriptionTopicStatus(

inherited
-
publishMessage(
String topic, MqttQos qualityOfService, Uint8Buffer data, {bool retain = false, List< MqttUserProperty> ? userProperties}) → int -
Publishes a message to the message broker.
Returns the message identifer assigned to the message.
Raises InvalidTopicException if the topic supplied violates the

inherited
-
publishUserMessage(
MqttPublishMessage message) → int -
Publishes a user supplied publish message to the message broker.
This allows the user to custom build the publish message as is needed.

Re-authenticate.
inherited
-
resubscribe(
) → void -
Re subscribe.
Unsubscribes all confirmed subscriptions and re subscribes them
without sending unsubscribe messages to the broker.
If an unsubscribe message to the broker is needed then use
unsubscribe
followed by subscribe for each subscription. Can be used in auto reconnect processing to force manual re subscription of all existing confirmed subscriptions.inherited -
sendAuthenticate(

Send an authenticate message to the broker.
inherited
-
subscribe(
String topic, MqttQos qosLevel) → MqttSubscription? -

inherited
-
subscribeWithSubscription(
MqttSubscription subscription) → MqttSubscription? -

The subscription to subscribe to.
Returns the subscription or null on failure
inherited
-
subscribeWithSubscriptionList(
List< MqttSubscription> subscriptions) → List<MqttSubscription> ? -
Initiates a topic subscription request to the connected broker
with a strongly typed data processor callback.
The list of subscriptions to subscribe to.
Note that user properties are set on a per message basis not a per
subscription basis, if you wish to send user properties then set
them on the first subscription in the list.
