SnackbarUnstyled API

API reference docs for the React SnackbarUnstyled component. Learn about the props, CSS, and other APIs of this exported module.


For examples and details on the usage of this React component, visit the component demo pages:


import SnackbarUnstyled from '@mui/base/SnackbarUnstyled';
// or
import { SnackbarUnstyled } from '@mui/base';
You can learn about the difference by reading this guide on minimizing bundle size.


Props of the native component are also available.

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.
The component used for the root node. Either a string to use a HTML element or a component.
If true, the autoHideDuration timer will expire even if the window is not focused.
The prop used to handle exited transition and unmount the component.
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.

function(event: React.SyntheticEvent<any> | Event, reason: string) => void
event: The event source of the callback.
reason: Can be: "timeout" (autoHideDuration expired), "clickaway", or "escapeKeyDown".
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.
