tryParseIso8601 function

DateTime? tryParseIso8601(
  1. Map<String, dynamic> json,
  2. String key
)

Same as parseIso8601, but returns null when the value under key is null or absent.

Implementation

DateTime? tryParseIso8601(Map<String, dynamic> json, String key) {
  if (json[key] == null) return null;
  return parseIso8601(json, key);
}
