fromJson static method

SpatioThread? fromJson(dynamic value)

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

Implementation

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

    return SpatioThread(
      id: mapValueOfType<String>(json, r'id')!,

      snippet: mapValueOfType<String>(json, r'snippet'),
      labels: json[r'labels'] is Iterable
