Are Dart 1 books still relevant for learning Dart 2 [duplicate]

Question

I read on many places that Dart 2 is not completely backward compatible with Dart. I found a list of books that are for Dart 1.x

https://dart.dev/resources/books

Can someone with Dart 1 and Dart 2 experience tell me if this books are relevant for learning Dart 2, can I use them or I should wait for release of some Dart 2 book.

I am not sure that this is the relevant place for this type of question, but I did't found anything more suiting in the Stack Exchange network.

Answer 1

Yes sure it is relevant. For the language instance creation keywords like new and const have become optional to help declutter the code. They’ve made a number of small changes and done some cleanup on the dart core libraries. Nothing huge to worry about :)
