fromJson static method

BulkAggregateQuestionItem? fromJson(dynamic value)

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

Implementation

// ignore: prefer_constructors_over_static_methods
static BulkAggregateQuestionItem? 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'aggId'), 'Required key "BulkAggregateQuestionItem[aggId]" is missing from JSON.');
      assert(json[r'aggId'] != null, 'Required key "BulkAggregateQuestionItem[aggId]" has a null value in JSON.');
      return true;
    }());

    return BulkAggregateQuestionItem(
      aggId: mapValueOfType<String>(json, r'aggId')!,
      questionId: mapValueOfType<String>(json, r'questionId'),
      questionIds: json[r'questionIds'] is Iterable
          ? (json[r'questionIds'] as Iterable).cast<String>().toList(growable: false)
