Lab 4 review

[igor-leshkevych]

Hi guys.
Nice app, adding native image picker was probably even a bit beyond the scope of this lab.

In general what I would improve:

1. Your global state is currently very small, and most screens use it only for read (there is just one widget that writes to it).
2. Cart screen doesn't have local state at all, and it only reads from global state, so there is no any write part done there.

Ideally I'd like to see local/global state and read/write on all screens, but it seems like this moment wasn't communicated properly from my side, so I won't reduce your score.

You all have 10/10.
