fromJson static method

NodeView? fromJson(dynamic value)

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

Implementation

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

    return NodeView(
      caps: json[r'caps'] is Iterable
          ? (json[r'caps'] as Iterable).cast<String>().toList(growable: false)
          : const [],
