fromJson static method

Label? fromJson(dynamic value)

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

Implementation

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