Part 4. Beyond foundations

The title of this part, in my mind, is debatable. In it, I talk about two main topics: interacting with outside data and testing. I’m not sure that these topics really are beyond the foundation. But neither are requirements for making an app.

Chapter 10, which is on working with data, isn’t a requirement because it makes assumptions: it covers using an HTTP library, working with JSON, and touches on Firebase a bit. These are extremely popular choices for tooling, but they aren’t the only ones. In that sense, they’re optional.

Testing is, of course, optional. It shouldn’t be, but it is. If you’re learning Flutter for the first time, you may not be concerned with testing. After all, you probably need to know what you’re testing first. That said, Flutter does make testing pretty easy, and it’s a valuable skill. It’s also the most exciting topic, so I’ve saved the best for last.
