Button List Select-CodePudding

I have a list of the button in my flutter app like the picture :enter image description here

and I need to select the container who I'm click on it for example, change the container color

CodePudding user response：

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

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;
            });
          },
        )),
