How to Map Flutter JSON Strings from List?

Question

I\'m successfully printing my response as String from my YouTube JSON url, but when I try to serialize through the \"items\" I get the following error Unhandled exception:

Answer 1

It looks like data['items'] is a List (i.e. a JSON Array), not a Map.

You can use list comprehension methods to help here:

final items = (data['items'] as List).map((i) => new CardInfo.fromJson(i));
for (final item in items) {
  print(item.id);
}
