Flutter BoxDecoration’s background color overrides the Container's background color, why?

Question

I have a Flutter Container widget and I defined a color for it (pink), but for some reason, the color in BoxDecoration overrides it (green). Why?

new Container(   color: Colors.pink,   decoration: new BoxDecoration(     borderRadius: new BorderRadius.circular(16.0),     color: Colors.green,   ), ); 

Answer 1

Container’s color is shorthand for BoxDecoration’s color, so BoxDecoration's color in the Container's decoration property overrides its Container's color.

Answer 2

Problem:

You can't use color and decoration at the same time. From docs:

The color and decoration arguments cannot both be supplied, since it would potentially result in the decoration drawing over the background color. To supply a decoration with a color, use decoration: BoxDecoration(color: color).

Solutions:

• Use only color:

  Container(   color: Colors.red ) 

• Use only decoration and provide color here:

  Container(   decoration: BoxDecoration(color: Colors.red) )
