Note that all following parameters can be used in global app parameters under toast property to set defaults for all toasts. For example:

var app = new Framework7({
  toast: {

    closeButton: true,
  }
});

Toast Methods & Properties

So to create Toast we have to call:

var toast = app.toast.create({ /* parameters */ })

After that we have its initialized instance (like toast variable in example above) with useful methods and properties:

toast.elToast HTML element
toast.$elDom7 instance with toast HTML element
