fromJson static method

ModemNetworkModem? fromJson(dynamic value)

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

Implementation

// ignore: prefer_constructors_over_static_methods
static ModemNetworkModem? 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(json.containsKey(key),
            'Required key "ModemNetworkModem[$key]" is missing from JSON.');
