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 classes API below for more details.
ClickAwayListenerProps	object	-	Props applied to the `ClickAwayListener` element. Deprecated－Use `slotProps.clickAwayListener` instead. This prop will be removed in a future major release. See Migrating from deprecated APIs for more details.
ContentProps	object	-	Props applied to the `SnackbarContent` element. Deprecated－Use `slotProps.content` instead. This prop will be removed in a future major release. See Migrating from deprecated APIs for more details.
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.
slotProps	{ clickAwayListener?: func \| object, content?: func \| object, root?: func \| object, transition?: func \| object }	{}	The props used for each slot inside.
slots	{ clickAwayListener?: elementType, content?: elementType, root?: elementType, transition?: elementType }	{}	The components used for each slot inside.
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. Deprecated－Use `slots.transition` instead. This prop will be removed in a future major release. See Migrating from deprecated APIs for more details.
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. Deprecated－Use `slotProps.transition` instead. This prop will be removed in a future major release. See Migrating from deprecated APIs for more details.

The ref is forwarded to the root element.
