Answer 1

TBH I'm not sure what your asking exactly, but this may or may not help you:

GestureDetector

This will let you respond to clicks on whatever it surrounds, so for example

    return
      GestureDetector(
          onTap: (){
            //Do something here to respond to a tap on the child Container()
          },
          child: Container(...) /// Your box

Now you can do something with it.

Hope this is what you were asking about

Answer 2

You can also use InkWell in this following way,

First you have to declare Color in your instances and after that you can use it in your onPress() widget.

Color _colorContainer = Colors.blue;

Now you can use it in your widget as follow:

         Ink(
            child: InkWell(
            child: Container(
            width: 200,
            height: 200,
            color: _colorContainer ,
          ),
          onTap: () {
            setState(() {
              _colorContainer = _colorContainer == Colors.red ? 
                    Colors.blue : 
                    Colors.red;
            });
          },
        )),
