You can learn about the difference by reading this guide on minimizing bundle size.


Props of the native component are also available.

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.
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.
Replace the SnackbarContent component.
Override or extend the styles applied to the component. See CSS API below for more details.
Props applied to the ClickAwayListener element.
Props applied to the SnackbarContent element.
If true, the autoHideDuration timer will expire even if the window is not focused.
When displaying multiple consecutive Snackbars from a parent rendering a single <Snackbar/>, add the key prop to ensure independent treatment of each message. e.g. <Snackbar key={message} />, otherwise, the message may update-in-place and features such as autoHideDuration may be canceled.
The message to display.
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.
