Props

Name	Type	Default	Description
open*	bool		If `true`, the component is shown.
anchorOrigin	{ horizontal: 'center' \| 'left' \| 'right', vertical: 'bottom' \| 'top' }	{ vertical: 'bottom', horizontal: 'right' }	The anchor of the `Snackbar`. On smaller screens, the component grows to occupy all the available width, the horizontal alignment is ignored.
animationDuration	number	300	The duration of the animation in milliseconds. This value is used to control the length of time it takes for an animation to complete one cycle. It is also utilized for delaying the unmount of the component. Provide this value if you have your own animation so that we can precisely time the component's unmount to match your custom animation.
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.
color	'danger' \| 'neutral' \| 'primary' \| 'success' \| 'warning'	'neutral'	The color of the component. It supports those theme colors that make sense for this component. To learn how to add your own colors, check out Themed components—Extend colors.
component	elementType		The component used for the root node. Either a string to use a HTML element or a component.
disableWindowBlurListener	bool	false	If `true`, the `autoHideDuration` timer will expire even if the window is not focused.
endDecorator	node		Element placed after the children.
invertedColors	bool	false	If `true`, the children with an implicit color prop invert their colors to match the component's variant and color.
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.
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"`.
onUnmount	func		A callback fired when the component is about to be unmounted.
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.
size	'sm' \| 'md' \| 'lg'	'md'	The size of the component. To learn how to add custom sizes to the component, check out Themed components—Extend sizes.
slotProps	{ clickAway?: func \| { children: element, disableReactTree?: bool, mouseEvent?: 'onClick' \| 'onMouseDown' \| 'onMouseUp' \| 'onPointerDown' \| 'onPointerUp' \| false, onClickAway: func, touchEvent?: 'onTouchEnd' \| 'onTouchStart' \| false }, endDecorator?: func \| object, root?: func \| object, startDecorator?: func \| object }	{}	The props used for each slot inside.
slots	{ clickAway?: elementType, endDecorator?: elementType, root?: elementType, startDecorator?: elementType }	{}	The components used for each slot inside. See Slots API below for more details.
startDecorator	node		Element placed before the children.
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.
variant	'outlined' \| 'plain' \| 'soft' \| 'solid'	'outlined'	The global variant to use. To learn how to add your own variants, check out Themed components—Extend variants.

The ref is forwarded to the root element.
