Chapter 4. Flutter UI: Important widgets, themes, and layout

This chapter covers

  • Starting your first Flutter app
  • Layout widgets
  • Themes and styling
  • Custom form elements
  • Builder patterns

Flutter isn’t just a framework. It’s a complete SDK. And perhaps the most exciting piece of this SDK to me, as a web developer, is the massive library of built-in widgets that make building the frontend of your mobile app easy.

This chapter and the following two are all about the user interface (UI) and making an app beautiful. This chapter includes exploring some of the widgets built into Flutter, layout, styling, and more. In the following chapters, I’ll go a bit further into the UI and talk about forms and user input, as well as animations. Figure 4.1
