Props

NameTypeDefaultDescription
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.

animationDurationnumber300

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.

autoHideDurationnumbernull

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.

componentelementType

The component used for the root node. Either a string to use a HTML element or a component.

disableWindowBlurListenerboolfalse

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

endDecoratornode

Element placed after the children.

invertedColorsboolfalse

If true, the children with an implicit color prop invert their colors to match the component's variant and color.

keyany

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.

onClosefunc

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".
onUnmountfunc

A callback fired when the component is about to be unmounted.

resumeHideDurationnumber

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.
