Passive notifications
The notifications you've examined so far in this chapter all have required input from the user. This is by design because it's important information that you're forcing the user to look at. However, you don't want to overdo this. For notifications that are important but not life-altering if ignored, you can use passive notifications. These are displayed in a less obtrusive way than modals and don't require any user action to dismiss them.
In this section, you'll create a Notification component that uses the Toast API for Android and creates a custom modal for iOS. It's called the Toast API because the information that's displayed looks like a piece of toast popping up. Toasts is a common component in Android to show some basic information that does not require user response.
Here's what the Android component looks like:
import React from "react";
import { ToastAndroid } from "react-native"...
