fromJson static method

OpenAIChoice? fromJson(dynamic value)

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

Implementation

// ignore: prefer_constructors_over_static_methods
static OpenAIChoice? 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(() {
      requiredKeys.forEach((key) {
        assert(json.containsKey(key), 'Required key "OpenAIChoice[$key]" is missing from JSON.');
        assert(json[key] != null, 'Required key "OpenAIChoice[$key]" has a null value in JSON.');
      });
      return true;
    }());

    return OpenAIChoice(
      finishReason: FinishReason.fromJson(json[r'finish_reason'])!,
      delta: OpenAIChoiceDelta.fromJson(json[r'delta']),
      message: OpenAIChoiceMessage.fromJson(json[r'message']),
      sources: Sources.fromJson(json[r'sources']),
      index: mapValueOfType<int>(json, r'index') ?? 0,
    );
