Overview of this book

“Anyone interested in developing Flutter applications for Android or iOS should have a copy of this book on their desk.” – Amazon 5* Review Lauded as the ‘Flutter bible’ for new and experienced mobile app developers, this recipe-based guide will teach you the best practices for robust app development, as well as how to solve cross-platform development issues. From setting up and customizing your development environment to error handling and debugging, The Flutter Cookbook covers the how-tos as well as the principles behind them. As you progress, the recipes in this book will get you up to speed with the main tasks involved in app development, such as user interface and user experience (UI/UX) design, API design, and creating animations. Later chapters will focus on routing, retrieving data from web services, and persisting data locally. A dedicated section also covers Firebase and its machine learning capabilities. The last chapter is specifically designed to help you create apps for the web and desktop (Windows, Mac, and Linux). Throughout the book, you’ll also find recipes that cover the most important features needed to build a cross-platform application, along with insights into running a single codebase on different platforms. By the end of this Flutter book, you’ll be writing and delivering fully functional apps with confidence.

How it works...

Container widgets can add all manner of effects to their child. Like scaffolds, they enable several customizations that can be explored and experimented with.

The primary property you will be designing with is BoxDecoration, which can draw the following:

  • Borders
  • Shadows
  • Colors
  • Gradients
  • Images
  • Shapes (rectangle or circles)

The container itself supports two decorations – the primary background decoration, and a foreground decoration, which is painted on top of the container's child.

Containers can also provide their own transforms (like how you rotated the second container), paddings, and margins.

Sometimes, you may prefer to add properties such as padding inside a container. In other cases, you may use a Padding widget and add Container as its child, as we did in this recipe. Both achieve exactly the same result, so it's up to you really.

In this recipe, we could also have rotated the box by supplying a Matrix4 to the transform property...
