Details

• anchorOrigin ⁠{ horizontal: 'center'| 'left'| 'right', vertical: 'bottom'| 'top' }⁠
  Default is 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
  Default is 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
  Default is - Replace the SnackbarContent component.

• classes object
  Default is - Override or extend the styles applied to the component.See CSS classes API below for more details.

• ClickAwayListenerProps object

• ContentProps object
  Default is - 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
  Default is FALSE If true, the autoHideDuration timer will expire even if the window is not focused.

• key any
  Default is - 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
  Default is - The message to display.

• onClose func
  Default is - 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) = voidevent The event source of the callback.reason Can be: "timeout" (autoHideDuration expired), "clickaway", or "escapeKeyDown".

• open bool
  Default is - If true, the component is shown.

• resumeHideDuration number
  Default is - 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.
