const

canUseChunkBackend → bool: Whether the chunk backend can be used (opfs and worker sync handles).
no setter
createWritable → bool: FileSystemFileHandle.createWritable() exists (Safari 26+).
final
crossOriginIsolated → bool: crossOriginIsolated === true.
final
fileSystemObserver → bool: FileSystemObserver exists (Chromium 133+).
final
fileSystemPickers → bool: showOpenFilePicker/showSaveFilePicker exist (Chromium only).
final
hashCode → int: The hash code for this object.
no setterinherited
opfs → bool: navigator.storage.getDirectory() exists (the OPFS namespace).
final
persisted → bool: navigator.storage.persisted().
final
quotaBytes → int?: navigator.storage.estimate().quota, when available.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
sharedArrayBuffer → bool: SharedArrayBuffer exists (requires COOP/COEP isolation).
final
storageBuckets → bool: navigator.storageBuckets exists (Chromium 122+).
final
syncAccessHandleInWorker → bool: A dedicated worker successfully created a sync access handle.
final
syncAccessHandleOnCurrentThread → bool: The current thread exposes createSyncAccessHandle (always false on the main thread, in every browser, as of 2026).
final
usageBytes → int?: navigator.storage.estimate().usage, when available.
final
workerError → String?: Why the worker handshake failed, when it did.
final

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
