Part 2. Flutter user interaction, styles, and animations

Flutter is, at its core, an SDK for writing the view layer of mobile (and soon, web) apps. It includes an engine and a lot that’s going on under the hood, but in this part, we mostly care about writing the UI itself.

This part of the book uses a static weather app to demonstrate how the UI aspect of Flutter is done. First, I’ll walk through some of the important base features and widgets that you’ll use again and again in Flutter apps. The chapters in this section—chapters 4, 5, and 6—cover the bare minimum of what you need to start a Flutter project.

In the following chapters, I’ll take deeper dives in two important UI-related subjects, forms and gestures, to handle user input and animations that make your app beautiful.
