import Notify from "devextreme/ui/notify"
Parameters:
message:

String

The message content.

stack:

Object

An object with the following structure: {position, direction}.

View Demo

To stack toast messages, specify the position field in the stack object.

The position field can be one of the following:

String Object
Cannot specify coordinates {x, y}, e.g. {100, 50}
'top left' {left, top}
'top center' Use window's and toast's width to calculate the center of the window, then use the 'top' field.
'top right' {right, top}
'left center' Use the 'left' field, then use window's and toast's height to calculate the center of the window.
'center' Use window's and toast's height and width to calculate the center of the window.
'right center' Use the 'right' field, then use window's and toast's height to calculate the center of the window.
'bottom left' {left, bottom}
'bottom center' Use window's and toast's width to calculate the center of the window, then use the 'bottom' field.
'bottom right' {right, bottom}

You can also specify the direction field in the stack object. It is a string that can be one of the following:

  • 'up-push'

  • 'down-push'

  • 'left-push'

  • 'right-push'

  • 'up-stack'

  • 'down-stack'

  • 'left-stack'

  • 'right-stack'

The image below shows the difference between directions with 'push' and 'stack' postfixes:

Toast Messages When Direction Is 'up-push' Toast Messages When Direction Is 'up-stack'

When you set the direction to 'up-push', the second and subsequent toasts push the first toast upwards. When you set the direction to 'up-stack', toasts stack on top of each other.

If you do not specify the direction field, its default value is 'down-push' for position: 'top left | top center | top right', and 'up-push' for other position options.

Note that toast messages disappear with an animated effect after their display time ends. The default hide animation duration for toast messages is 400 milliseconds. If multiple messages can stack in your application and block important visual elements, you may want to disable the animation or reduce its duration.
