Port class

Constructors

Port({required String name, required JSFunction disconnect, required JSFunction postMessage, MessageSender? sender})

Port.fromJS(Port _wrapped)

Properties

disconnect ↔ JSFunction

Immediately disconnect the port. Calling disconnect() on an already-disconnected port has no effect. When a port is disconnected, no new events will be dispatched to this port.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

name ↔ String

The name of the port, as specified in the call to runtime.connect.

getter/setter pair

onDisconnect → EventStream<Port>

Fired when the port is disconnected from the other end(s). runtime.lastError may be set if the port was disconnected by an error. If the port is closed via $(ref:Port.disconnect disconnect), then this event is only fired on the other end. This event is fired at most once (see also Port lifetime).

no setter

onMessage → EventStream<PortOnMessageEvent>

This event is fired when $(ref:Port.postMessage postMessage) is called by the other end of the port.

no setter

postMessage ↔ JSFunction

Send a message to the other end of the port. If the port is disconnected, an error is thrown.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

sender ↔ MessageSender?

This property will only be present on ports passed to $(ref:runtime.onConnect onConnect) / $(ref:runtime.onConnectExternal onConnectExternal) / $(ref:runtime.onConnectExternal onConnectNative) listeners.

getter/setter pair

toJS → Port

no setter
