Static Methods

activeServiceWorkerUrl() → String?

Script URL of the service worker serving this page, e.g. ".../flutter_service_worker.js?v=123".

baseUrl() → String

Absolute URL the app is deployed under, always with a trailing slash.

clearCaches() → Future<void>

Deletes every CacheStorage bucket, including the ones the Flutter service worker fills.

documentUrl() → String

Absolute URL of the document currently shown, including query and fragment.

fetch(String url, String cacheMode) → Future<String?>

Downloads url with the given HTTP cache mode ("no-store", "force-cache", "reload", ...). Null on any failure, so callers can treat "offline" and "missing" the same way.

isEmbedded() → bool

True when the page runs inside an iframe or a native WebView user-agent.

isStandalone() → bool

True when the site is running as an installed PWA (launched from the home screen).

listenMessage(void onMessage(String origin, Map<String, dynamic> data)) → void Function()

Subscribes to browser window "message" events; returns a disposer that removes the listener.

listenVisible(void onVisible()) → void Function()

Runs onVisible every time the tab comes back to the foreground; returns a disposer.

reload(String? url) → void

Reloads the page, or navigates to url without adding a history entry.

revalidate(List<String> urls) → Future<void>

Re-downloads urls and overwrites their HTTP cache entries, so the next navigation reads the server copy even for Cache-Control: immutable assets.

serviceWorkerHasPendingUpdate() → Future<bool>

Asks every registration to re-check the server; true when a newer worker is installing or waiting.

unregisterServiceWorkers() → Future<void>

Releases any waiting worker and unregisters every service worker of this origin.

userAgent() → String
