Carmine Zaccagnino says: Not the only instance. I didn't think it would matter, but if you're picking up on it I need to fix it and move the starting apps to a separate folder. Will be done for the next beta, thank you for the feedback again!

Can you explain the need for the Padding widget, in light of the Container widget also having a 'padding' and 'child' option. Flutter documentation st...more...
Carmine Zaccagnino says: I always find it more intuitive to just use Padding whenever I only need padding (one unnecessary layer of abstraction removed), and that's also reflected by the examples in the book (I'm quite certain I used the Padding widget several times). It's also used often enough I don't feel like it should be left out and it's very easy to remember, unlike some other widgets I left out. It's like using a dedicated credit card instead of using the credit card function in a multifunctional bank card: it's just as easy, a bit more intuitive (for me at least) and it has a place in the world just like I believe the Padding widget has a place in this book because it's used often. Also, I'm not hiding the fact that the Container can be used to add padding: it's mentioned when I talk about the Container so, in the end, it's up to the reader to choose which one to use. Thank you very much for your comprehensive and useful feedback again!

Carmine Zaccagnino says: We decided against it, we believe the chapter is good as it is now and splitting it isn't necessary, thank you anyway for the suggestion.

Carmine Zaccagnino says: Thank you, I made a mess of the quotes to enclose that code section so the backslashes aren't shown in the book, that also explains that single curly quote you mentioned.
