The following are the option to render the toast using the utility function.

Show Toast with predefined types

The Toast component support 4 types of predefined toast with essential colors for various situations which can be shown using the ToastUtility.show by just defining the type of the toast without defining any class names. The following options are used as an argument on calling the utility function for predefined types:

Options Description
content Specifies the content that can be displayed on the Toast.
type Specifies the type of the predefined Toasts. The 4 types of predefined toasts are Information, Success, Error, Warning
timeOut Specifies the Toast display time duration on the page in milliseconds. Once the time expires, Toast message will be removed. Setting 0 as a time out value displays the Toast on the page until the user closes it manually.
