You can make List.builder or listview or use scrollable layout using scroll widget in flutter. below is a code you can customized according to your need i did it with List.builder

List litems = ["1","2","3","4"];

return Scaffold(
  backgroundColor: Colors.grey[200],
  body: Padding(
    padding: const EdgeInsets.all(18.0),
    child: Column(
      children: [
        Padding(
          padding: const EdgeInsets.fromLTRB(10.0, 0.0, 0.0, 18.0),
          child: Align(
            alignment: Alignment.topLeft,
            child: ListTile(
