Hi!

I'm really sorry for the late reply. I'm not very familiar with Dart, but it's very likely that you'll be able to follow the course just fine. It doesn't require any specific knowledge of Java, C# or PHP. The OOP principles and refactoring techniques covered in the course should be applicable to any modern OOP language.

Здравствуйте!

Понимаю вашу проблему. Краткая инструкция к UML является частью полной книги "Погружение в паттерны проектирования". Если вы не хотите покупать книгу, то базовую информацию об UML можно почерпнуть здесь: https://ru.wikipedia.org/wiki/%D0%94%D0%B8%D0%B0%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%B0_%D0%BA%D0%BB%D0%B0%D1%81%D1%81%D0%BE%D0%B2

Hi! No, sorry, not yet.

Hi Eric!

As far as I know, C is not an OOP language, therefore the patterns aren't applicable there. Probably there are design patterns specific to the C language, but since they are very specialized, I doubt that they'll be covered here.
