How to give dynamic no of PopupMenuItem to the PopupMenuButton with flutter?

Question

How to set dynamically no of PopupMenuItem to the PopupMenuButton with index like ListView.builder().

Actually i'm using FutureBuilder to get data from the api and in response , 4 items are fetched means it gives dynamic no of items. and want to show them into PopupMenuItem in list form . but there is no count constructor in PopupMenuButton unlike ListView.builder().

Code:

FutureBuilder<CommonModel>(
                future: futureListMaterialStatusCommonModel,
                builder:(BuildContext context, AsyncSnapshot<CommonModel> snapshot ){
                  if(!snapshot.hasData){
                    return Text("loading...");
                  }
                   if(snapshot.hasError){
                    return Text(snapshot.error);
                  }
                 //I tried to get solution by loop before showing items but went wrong
                 for(int i ; i< snapshot.data.content.length; i++){
                    itemList.add(
                      PopupMenuItem(
                        value: snapshot.data.content[i].title,//919876543210,
                        child: Text(
                          snapshot.data.content[0].title,
                          style: TextStyle(
                          color: Colors.black, fontWeight: FontWeight.w700),
                        ),
                      ),
                    );
                  }

                 return  PopupMenuButton<String>(
                    itemBuilder: (context) => [
                      PopupMenuItem(
                        value: snapshot.data.content[0].title,
                        child: Text(
                          snapshot.data.content[0].title,
                          style: TextStyle(
                          color: Colors.black, fontWeight: FontWeight.w700),
                        ),
                      ),

                    ],
                    onSelected: (value) { 
                      setState(() {
                        materialStatus = value;
                      });

                    },
                    child: materialStatus==null? Text("Select...", 
                      style: TextStyle(color:Colors.orange),)
                      :Text(materialStatus, 
                      style: TextStyle(color:Colors.black, fontWeight: FontWeight.bold),)
                  );
                } ,
              )

Finally I made it. it was so simple, really so dumb I'm.

return  PopupMenuButton<String>(
                   itemBuilder: (context ) => 
                  snapshot.data.content
                     .map((item) => PopupMenuItem<String>(
                           value: item.title,
                           child: Text(
                             item.title,
                           ),
                         ))
                     .toList(),


                   onSelected: (value) { 
                     setState(() {
                       materialStatus = value;
                     });

                   },
                   child: materialStatus ==null? Text("Select...", 
                     style: TextStyle(color:Colors.orange),)
                     :Text(materialStatus, 
                     style: TextStyle(color:Colors.black, fontWeight: FontWeight.bold),)
                 );
