          The title and onPress handler are required. It is recommended to set accessibilityLabel to
          help make your app usable by everyone.

          Adjust the color in a way that looks standard on each platform. On iOS, the color prop
          controls the color of the text. On Android, the color adjusts the background color of the
          button.
        </Text>
        <Button
          title="Press me"
          color="#f194ff"
          onPress={() => Alert.alert('Button with adjusted color pressed')}

          This layout strategy lets the title define the width of the button.
