Setting background color

In Flutter, you set the background color using the color property
or the decoration property of a Container.
However, you cannot supply both, since it would potentially
result in the decoration drawing over the background color.
The color property should be preferred
when the background is a simple color.
For other cases, such as gradients or images,
use the decoration property.

The CSS examples use the hex color equivalents to the Material color palette.
