autoHideDurationnumber | nullnull

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.


If true, the autoHideDuration timer will expire even if the window is not focused.

onClose(event: React.SyntheticEvent<any> | Event | null, reason: SnackbarCloseReason) => void-

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.


If true, the component is shown.


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.
