You can copy paste run full code below
You can use MouseRegion's onHover attribute

code snippet

void _incrementExit(PointerEvent details) {
    setState(() {
      textColor = Colors.blue;
      _exitCounter++;
    });
  }

void _updateLocation(PointerEvent details) {
    setState(() {
      textColor = Colors.red;
      x = details.position.dx;
      y = details.position.dy;
    });
  }
  
return MouseRegion(
      onEnter: _incrementEnter,
      onHover: _updateLocation,
      onExit: _incrementExit,
      child: FlatButton(
        color: Colors.white,
        textColor: Colors.teal[700], //when hovered text color change
        shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.circular(5),
