Cannot provide both a color and a decoration to a Container

Issue

every time that i restart the code to check app , i have an error that say Cannot provide both a color and a decoration , the color argument is just a short hand for "decoration : new Boxdecoration( color : color ) "
maybe its true and i have a mistake but its doesn’t say where is it?
when i delete something like font size , a widget or something that has not any correlate to error , and reload the app , app start without any problem or error that show…

Solution

Try to add color inside decoration like this:

Container(
  decoration: BoxDecoration(
    color: Colors.red
  ),
  child: //add you desired code here
),

This will definitely help you
