I’m on Compose Beta 07 and using Gradle 7 Beta 2. Most code in V1.1 of the Compose Book does not build without modifications. Chap 12 (animations) really needs tons of changes. I simply gave up rather than spending so much time fixing the compiler issues. I suspect that there are some merge related changes in Chap 12 from 1.0 to 1.1. I suspect this mainly because for previous chapters, I could change gradle files for versions and build the code without much problem. It would be better if someone fixes these problems. Its difficult to learn compose because most time and efforts are consumed in building the code.
It would have been better if the Section 3 code was an incremental build. I see that if I code-along and finish one chapter, the following project does not build on the previous one. The code for the new chapter has new files added and one has to start with that code again. Incremental code would have really helped.
