MediaEncryptedEvent 构造函数
实现
factory MediaEncryptedEvent(String type, [Map? eventInitDict]) {
if (eventInitDict != null) {
var eventInitDict_1 = convertDartToNative_Dictionary(eventInitDict);
return MediaEncryptedEvent._create_1(type, eventInitDict_1);
}
return MediaEncryptedEvent._create_2(type);
}
