Object that holds the loading state object coming from dash-renderer
Logical | character | numeric. Used to allow user interactions in this component to be persisted when the component - or the page - is refreshed. If `persisted` is truthy and hasn't changed from its previous value, a `value` that the user has changed while using the app will keep that change, as long as the new `value` also matches what was given originally. Used in conjunction with `persistence_type`.
List of a value equal to: 'value's. Properties whose user interactions will persist after refreshing the component or the page. Since only `value` is allowed this prop can normally be ignored.
A value equal to: 'local', 'session', 'memory'. Where persisted user changes will be stored: memory: only kept in memory, reset on page refresh. local: window.localStorage, data is kept after the browser quit. session: window.sessionStorage, data is cleared once the browser quit.
