Simple three-column layout

To start things off, let's implement a simple layout with three sections that flex in the direction of the column (top to bottom). Let's start by taking a look at the resulting screen:

The idea, in this example, is that you've styled and labeled the three screen sections so that they stand out. In other words, these components wouldn't necessarily have any styling in a real application since they're used to arrange other components on the screen.

Let's take a look at the components used to create this screen layout:

import React from "react";
import { Text, View } from "react-native";
import styles from "./styles";

export default function App() {
  return (
    <View style={styles.container}>
      <View style={styles.box}>
        <Text style={styles.boxText}>#1</Text>
      </View>
      <View style={styles.box}>
        <Text style={styles.boxText}>#2</Text&gt...
