Custom effects in todos app.

These are the custom effects we have created for the todos app:

toast.show

The toast.show effect is used to display a toast.

Example:

import { toast } from "../../effects/toast";

registerEventHandler(
    "displayError", 
    function displayError(coeffects, { message }) {
        return toast.show({
            text: message,
            milliseconds: 3000
        });
    }
);

In the previous example, the event handler for displayError event returns a toast.show effect that will show a message during 3000 milliseconds.

The parameters for the toast.show effect is an object comprised of two properties:

1. text: the text that will be displayed by the toast.

2. milliseconds: the time in milliseconds that the toast will be visible.
