The following animation shows the app’s behavior:

Create a list to hold the parallax items

To display a list of parallax scrolling images,
you must first display a list.

Create a new stateless widget called ParallaxRecipe.
Within ParallaxRecipe, build a widget tree with a
SingleChildScrollView and a Column, which forms 
a list.

Display items with text and a static image

Each list item displays a rounded-rectangle background
image, exemplifying one of seven locations in the world.
Stacked on top of that background image is the 
name of the location and its country,
positioned in the lower left. Between the 
background image and the text is a dark gradient,
which improves the legibility 
of the text against the background.
