how to wrap with inkwell so every individual button in a row can work in flutter

You can add gesturedetector to this widget and then call the function in your code

Widget _buildSoftUIMenu(icon, color, title,{Function ontap}) {
  return GestureDetector(onTap:onTap,  child: Column(
    crossAxisAlignment: CrossAxisAlignment.center,
    children: <Widget>[
      Container(
        height: 100.0,
        width: 100.0,
        margin: EdgeInsets.only(bottom: 16.0),
        decoration: BoxDecoration(
            color: bgColor,
            borderRadius: BorderRadius.circular(16),
            boxShadow: [
              BoxShadow(
                color: lightColor.withOpacity(0.1),
                offset: Offset(-6, -6),
                spreadRadius: 0,
                blurRadius: 6,
              ),
              BoxShadow(
                color: Colors.black26,
                offset: Offset(6, 6),
                spreadRadius: 0,
                blurRadius: 6,
              )
            ]),
        child: Center(
          child: Icon(
            icon,
            size: 46,
            color: color,
          ),
        ),
      ),
      Text(
        title,
        style: subtitleStyle,
      ),
    ],
  );
}

then you can now build your widgets

_buildSoftUIMenu(LineAwesomeIcons.dot_circle_o,Colors.deepOrangeAccent, 'Optional Books',onTap:(){ print("######")}, 

You can add this code inside your ** _buildSoftUIMenu** function

Widget _buildSoftUIMenu(icon, color, title) {
  return InkWell(
    onTap: onTapCallback,
    child: Column(
      crossAxisAlignment: CrossAxisAlignment.center,
      children: <Widget>[
        ....
        ....
        ....
      ],
    );
  );
}
