There are two chapters with the number 6 in the title heading.
page 102 “Chapter 6: Intro to controls: Text & Image”
Page 128 “Chapter 6: State & Data Flow”
However the table of contents has page 128 listed as chap 7.
More importantly here is an editorial suggestion: the State & Data flow chapter departs from the tutorial format. It is structured as a commentary upon the example Kuchi app rather than the point by point construction of the prior tutorial chapters.
In fact from some of the writing it almost feels like there was chapter deleted at the last minute where the example was constructed. Or alternatively in the rush to publish the construction segments did not get completed.
For example page 136 "“You’ve already decided that your WelcomeView and your RegisterView need to share some information. Initially, you identified the shared information to be the name of your user” – actually the reader has not done anything yet in this chapter except read commentary and code.
I agree with the intro that the topic is very important. The tutorial approach of the other chapters has been working very well with my personal learning style. Can you consider a major expansion of this chapter in the next edition? Thanks !!! Will L-B
