darkBackground constant
Color
const darkBackground
FlexColors standard for dark background.
Slightly darker than its Material counter part, so we can blend in more primary color without getting too light too soon.
It is also a tad darker then darkSurface because we will be blending in more of the primary color into it. Making its starting value darker allows us to do so without it getting too light when we blend in more primary color.
Implementation
static const Color darkBackground = Color(0xFF101010);
