Severe performance issue: content widget is being rebuit infinitely

My widget code:

GestureDetector(
      onTap: () {
        setState(() {
          showToolTip = !showToolTip;
        });
      },

      child: SimpleTooltip(
        show: showToolTip,
        backgroundColor: const Color(0xFFFFFACF),
        customShadows: const <BoxShadow>[],

        tooltipTap: () {
          print("Tooltip tap");
        },

        animationDuration: Duration(milliseconds: 300),
        tooltipDirection: TooltipDirection.down,
        content: Text(
          "Hello world",
          style: TextStyle(
            color: Colors.black,
            height: 1,
            fontSize: 18,
            fontFamily: 'SFProDisplay',
          ),
        ),
        minHeight: 0,
        minWidth: 0,
        borderWidth: 0,
        ballonPadding: EdgeInsets.symmetric(vertical: 4, horizontal: 15),
        borderRadius: 20,
        arrowBaseWidth: 22,
        arrowLength: 15,
        child: Container(height: 100, width:  100, color: Colors.black,),
      ),
    )
