fromJson static method

CommentLogEntry? fromJson(dynamic value)

Returns a new CommentLogEntry instance and imports its values from value if it's a Map, null otherwise.

Implementation

// ignore: prefer_constructors_over_static_methods
static CommentLogEntry? fromJson(dynamic value) {
  if (value is Map) {
    final json = value.cast<String, dynamic>();

    // Ensure that the map contains the required keys.
    // Note 1: the values aren't checked for validity beyond being non-null.
    // Note 2: this code is stripped in release mode!
    assert(() {
      assert(json.containsKey(r'd'), 'Required key "CommentLogEntry[d]" is missing from JSON.');
      assert(json[r'd'] != null, 'Required key "CommentLogEntry[d]" has a null value in JSON.');
      assert(json.containsKey(r't'), 'Required key "CommentLogEntry[t]" is missing from JSON.');
      assert(json[r't'] != null, 'Required key "CommentLogEntry[t]" has a null value in JSON.');
      return true;
    }());

    return CommentLogEntry(
      d: mapDateTime(json, r'd', r'')!,
      t: CommentLogType.fromJson(json[r't'])!,
      da: CommentLogData.fromJson(json[r'da']),
    );
