Variables

read onlyclients:Clients

Contains the Clients object associated with the service worker.

onactivate:Function

An event handler fired whenever an activate event occurs — when a ServiceWorkerRegistration acquires a new ServiceWorkerRegistration.active worker.

onfetch:Function

An event handler fired whenever a fetch event occurs — when a GlobalFetch.fetch is called.

oninstall:Function

An event handler fired whenever an install event occurs — when a ServiceWorkerRegistration acquires a new ServiceWorkerRegistration.installing worker.

onmessage:Function

An event handler fired whenever a message event occurs — when incoming messages are received. Controlled pages can use the MessagePort.postMessage() method to send messages to service workers. The service worker can optionally send a response back via the MessagePort exposed in event.data.port, corresponding to the controlled page.

onnotificationclick:Function

An event handler fired whenever a notificationclick event occurs — when a user clicks on a displayed notification.

onnotificationclose:Function

An event handler fired whenever a notificationclose event occurs — when a user closes a displayed notification.

onpush:Function

An event handler fired whenever a push event occurs — when a server push notification is received.

onpushsubscriptionchange:Function

An event handler fired whenever a pushsubscriptionchange event occurs — when a push subscription has been invalidated, or is about to be invalidated (e.g. when a push service sets an expiration time.)

read onlyregistration:ServiceWorkerRegistration

Contains the ServiceWorkerRegistration object that represents the service worker's registration.

Methods

skipWaiting():Promise<Void>

Allows the current service worker registration to progress from waiting to active state while service worker clients are using it.

Throws:

null

DOMError

Inherited Variables

Defined by WorkerGlobalScope

read onlycaches:CacheStorage

read onlycrypto:Crypto

read onlyindexedDB:Factory

read onlyisSecureContext:Bool

read onlylocation:WorkerLocation

Returns the WorkerLocation associated with the worker. It is a specific location object, mostly a subset of the Location for browsing scopes, but adapted to workers.

read onlynavigator:WorkerNavigator

onerror:(EitherType<Event, String>, String, Int, Int, Dynamic) ‑> Dynamic

Is an EventHandler representing the code to be called when the error event is raised.

onoffline:Function

Is an EventHandler representing the code to be called when the offline event is raised.

ononline:Function

Is an EventHandler representing the code to be called when the online event is raised.

read onlyorigin:String

read onlyperformance:Performance

Returns the Performance associated with the worker. It is a regular performance object, except that only a subset of its property and methods are available to workers.

read onlyself:WorkerGlobalScope

Returns a reference to the WorkerGlobalScope itself. Most of the time it is a specific scope like DedicatedWorkerGlobalScope,  SharedWorkerGlobalScope or ServiceWorkerGlobalScope.
