fromJson static method

AttachmentInput? fromJson(dynamic value)

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

Implementation

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