title: FlatList not showing up
body: <p>I am following a tutorial video for React Native. Everything is working well besides the FlatList, I am unable to make it show up on the simulator. I am using expo, while this tutorial is done using bare. Maybe that is causing the issue, but I am not sure how to resolve it.</p>
  <p>Here is a link to the video: <a href="https://www.youtube.com/watch?v=GPu1ax1Fga0&amp;t=2179s" rel="nofollow noreferrer">https://www.youtube.com/watch?v=GPu1ax1Fga0&amp;t=2179s</a></p>
  <p>Link to the github for the source code: <a href="https://github.com/mattfrances/FoodAppUI" rel="nofollow noreferrer">https://github.com/mattfrances/FoodAppUI</a></p>
  <p>This is the code for the FlatList</p>
  <pre><code>        &lt;View style={styles.categoriesWrapper}&gt;
            &lt;Text style={styles.categoriesTitle}&gt;Categories&lt;/Text&gt;
            &lt;View style={styles.categoriesListWrapper}&gt;
              &lt;FlatList
                data={categoriesData}
                renderItem={renderCategoryItem}
                keyExtractor={(item) =&gt; item.id}
                horizontal={true}
              /&gt;
            &lt;/View&gt;
          &lt;/View&gt;
  </code></pre>
  <p>Here is the renderCategoryItem code:</p>
  <pre><code>const renderCategoryItem = ({ item }) =&gt; {
          return (
            &lt;View
              style={[
                styles.categoryItemWrapper,
                {
                  backgroundColor: item.selected ? colors.primary : colors.white,
                  marginLeft: item.id == 1 ? 20 : 0,
                },
              ]}&gt;
              &lt;Image source={item.image} style={styles.categoryItemImage} /&gt;
              &lt;Text style={styles.categoryItemTitle}&gt;{item.title}&lt;/Text&gt;
              &lt;View
                style={[
                  styles.categorySelectWrapper,
                  {
                    backgroundColor: item.selected ? colors.white : colors.secondary,
                  },
                ]}&gt;
                &lt;Feather
                  name=&quot;chevron-right&quot;
                  size={8}
                  style={styles.categorySelectIcon}
                  color={item.selected ? colors.black : colors.white}
                /&gt;
              &lt;/View&gt;
            &lt;/View&gt;
          );
        };
  </code></pre>
  <p>Any help would be greatly appreciated!</p>
