How to do looping using ListView.builder and for in flutter

Question

I am trying to loop my data using for and ListView.builder, here is part of my code

Widget listData(Data myList) {
  List<Check> tab = myList.data.listItem;
  List<Widget> list = new List<Widget>();
  for (var i = 0; i < tab.length; i++) {
    List<User> user= myList.data.listItem[i].detail;
    list.add(Container(
      child: ListView.builder(
          scrollDirection: Axis.vertical,
          itemCount: user.length,
          itemBuilder: (context, index) {
            return Text("check= $i");
          }),
    ));
  }
  return Center(child: new Column(children: list));
}

I have 6 data..but using that code I always get the first data only... the other data doesn't show up in my screen... is there something that I should do to show my all data using ListView.builder and for looping

Solution

Consider giving some height to the Container say some 50 or 100..that will solve your issue..

I have edited my question... tab.length in my code is 3 but I only get first looping and the result is in the picture inside my question

Where are you calling listData..?

[uyhaW]

@override Widget build(BuildContext context) { return listData(); }

I am calling listData like that.. I am calling it inside my Stateful widget

Try to give some height to the Container that you mentioned in the question..say some 50 or 100.. not sure if it works.. just give it a try..
