Props

Props of the native component are also available.

Name	Type	Default	Description
action	node		The action to display. It renders after the message, at the end of the snackbar.
anchorOrigin	{ horizontal: 'center' \| 'left' \| 'right', vertical: 'bottom' \| 'top' }	{ vertical: 'bottom', horizontal: 'left' }	The anchor of the `Snackbar`. On smaller screens, the component grows to occupy all the available width, the horizontal alignment is ignored.
autoHideDuration	number	null	The number of milliseconds to wait before automatically calling the `onClose` function. `onClose` should then set the state of the `open` prop to hide the Snackbar. This behavior is disabled by default with the `null` value.
children	element		Replace the `SnackbarContent` component.
classes	object		Override or extend the styles applied to the component. See CSS API below for more details.
ClickAwayListenerProps	object		Props applied to the `ClickAwayListener` element.
ContentProps	object		Props applied to the `SnackbarContent` element.
disableWindowBlurListener	bool	false	If `true`, the `autoHideDuration` timer will expire even if the window is not focused.
key	any		When displaying multiple consecutive snackbars using a single parent-rendered `<Snackbar/>`, add the `key` prop to ensure independent treatment of each message. For instance, use `<Snackbar key={message} />`. Otherwise, messages might update in place, and features like `autoHideDuration` could be affected.
message	node		The message to display.
onClose	func		Callback fired when the component requests to be closed. Typically `onClose` is used to set state in the parent component, which is used to control the `Snackbar` `open` prop. The `reason` parameter can optionally be used to control the response to `onClose`, for example ignoring `clickaway`. Signature:`function(event: React.SyntheticEvent \| Event, reason: string) => void` `event` The event source of the callback. `reason` Can be: `"timeout"` (`autoHideDuration` expired), `"clickaway"`, or `"escapeKeyDown"`.
open	bool		If `true`, the component is shown.
resumeHideDuration	number		The number of milliseconds to wait before dismissing after user interaction. If `autoHideDuration` prop isn't specified, it does nothing. If `autoHideDuration` prop is specified but `resumeHideDuration` isn't, we default to `autoHideDuration / 2` ms.
sx	Array<func \| object \| bool> \| func \| object		The system prop that allows defining system overrides as well as additional CSS styles. See the `sx` page for more details.
TransitionComponent	elementType	Grow	The component used for the transition. Follow this guide to learn more about the requirements for this component.
transitionDuration	number \| { appear?: number, enter?: number, exit?: number }	{ enter: theme.transitions.duration.enteringScreen, exit: theme.transitions.duration.leavingScreen, }	The duration for the transition, in milliseconds. You may specify a single timeout for all transitions, or individually with an object.
TransitionProps	object	{}	Props applied to the transition element. By default, the element is based on this `Transition` component.

The ref is forwarded to the root element.
