Implementation

factory RegisterMap.fromJson(String jsonString) {
  final json = jsonDecode(jsonString) as Map<String, dynamic>;
  return RegisterMap(
    slaveId: json['slaveId'] as int,
    deviceName: json['deviceName'] as String?,
    registers: (json['registers'] as List)
        .map((r) => RegisterDefinition.fromJson(r as Map<String, dynamic>))
        .toList(),
  );
}
