<paper-toast>
paper-toast provides a subtle notification toast. Only one paper-toast will
be visible on screen.
Use opened to show the toast:
Example:
<paper-toast text="Hello world!" opened></paper-toast>Also open() or show() can be used to show the toast:
Example:
<paper-button on-click="openToast">Open Toast</paper-button>
<paper-toast id="toast" text="Hello world!"></paper-toast>
...
openToast: function() {
this.$.toast.open();
}Set duration to 0, a negative number or Infinity to persist the toast on screen:
Example:
<paper-toast text="Terms and conditions" opened duration="0">
<a href="#">Show more</a>
</paper-toast><paper-toast> is affected by the stacking context of its container. Adding <paper-toast> inside elements that create a new stacking context - e.g. <app-drawer>, <app-layout> or <iron-list> - might result in toasts partially obstructed or clipped. Add <paper-toast> to the top level (<body>) element, outside the structure, e.g.:
<!-- ... -->
</app-drawer-layout>
<paper-toast id="toast"></paper-toast>
</template>You can then use custom events to communicate with it from within child components, using addEventListener and dispatchEvent.
