    If you would have more than a fixed number of 5 rows, the ListView.builder constructor is what you want:

    ListView.builder(
  itemCount: items.length,
  itemBuilder: (context, index) async {
    final response = await http.get('https://anyurl/getData/contentId/${index}');

    final parsedResponse = parseResponse(response);

    return ListTile(
      title: Text('${parsedResponse.title}'),
    );
  },
);

    The ListView builder gives you the index of the list item currently being built and lets you create any widgets that are displayed as elements.

    parseResponse is a dummy function, which of course does not exist, because it has to be implemented by yourself.
