CodePudding user response：

// menuList is your userModel list with name and Like/unline(bool)

 var list = menuNameList.where((element) => element == true).toList();

// this listview in the main screen // I assume you know how to build a Child widget(MyUserRow)

ListView.builder(
                itemCount: list.length 
                          itemBuilder: (context, index) =>
                              MyUserRow(
                            model: list[index],
                            index: index,
                            callback: myCallBack,
                            
                          ),),

// in MyUser widget you have the button or on Parent view clicked which call our callback

 IconButton(
              icon: Icon(Icons.search),
              onPressed: () {
                 callback(id); 
                 // pass your model or just id for your new screen
                // or next screen directly 
            Navigator.push(
            context,
            MaterialPageRoute(builder: (context) => SecondRoute(userId/UserModel())),
            );

        }),
