Function useStorage

Returns {
    clear: () => void;
    getItem: <T = unknown>(key: string, defaultValue?: T) => T | null;
    markUnsynced: (key: string) => void;
    removeItem: (key: string) => void;
    setItem: <T = unknown>(key: string, value: T) => void;
}

• clear: () => void

  The wall-side route for clearAppStorage (GPHONE-16 step 4): that facet is a bare function, not a factory, so a remoteCall naming it has no member to call. This member is what the iframe twin's clearAppStorage(appId) actually reaches.

• getItem: <T = unknown>(key: string, defaultValue?: T) => T | null

• markUnsynced: (key: string) => void

  Serves the iframe persisted twin's markUnsynced (GPHONE-16 step 4): an add-on cannot import settingsSync directly, so this is the one member of the facet that reaches it on the add-on's behalf.

• removeItem: (key: string) => void

• setItem: <T = unknown>(key: string, value: T) => void
