position: PopupMenuPosition.under,
child: Text(
'Agenturen & Clubs',

<PopupMenuEntry>[
const PopupMenuItem(

class OverlayAnimatedGridElement extends StatefulWidget {
OverlayAnimatedGridElement(this.imagepath);
final String imagepath;
//  final String postTitle;
//  final String postDetail;
@override
_OverlayAnimatedGridElementState createState() =>
_OverlayAnimatedGridElementState();
}
class _OverlayAnimatedGridElementState extends State<OverlayAnimatedGridElement>
with TickerProviderStateMixin {
bool isHovered = false;
@override
void initState() {
super.initState();
}
hoverActivation(hoverState) {
setState(() {
isHovered = hoverState;
});
print("activated" + hoverState.toString());
}
@override
Widget build(BuildContext context) {
return Center(
child: Container(
color: Colors.red,
height: 200,
width: 300,
child: Stack(
children: [
Image.network(widget.imagepath),
MouseRegion(
onEnter: (event){
hoverActivation(true);
},
onExit: (event){
hoverActivation(false);
},
child: AnimatedContainer(
duration: Duration(milliseconds: 200),
color: Colors.black.withOpacity(isHovered ? 0.5 : 0),
