ion-toast

Contents

A Toast is a subtle notification commonly used in modern applications. It can be used to provide feedback about an operation or to display a system message. The toast appears on top of the app's content, and can be dismissed by the app to resume user interaction with the app.

Creating

All of the toast options should be passed in the create method. The message to display should be passed in the message property. The showCloseButton option can be set to true in order to display a close button on the toast. See the properties below for all available options.

Positioning

Toasts can be positioned at the top, bottom or middle of the viewport. The position can be passed upon creation. The possible values are top, bottom and middle. If the position is not specified, the toast will be displayed at the bottom of the viewport.

Dismissing

The toast can be dismissed automatically after a specific amount of time by passing the number of milliseconds to display it in the duration of the toast options. If showCloseButton is set to true, then the close button will dismiss the toast. To dismiss the toast after creation, call the dismiss() method on the instance.
