Notes

In this section will complete a UI challenge and build a stopwatch application.

The two most important topics we will cover are tickers and matrix transforms.

• Tickers are at the foundation of the Flutter animation framework. By learning what they are and how to use them, you'll get a better understanding of how animations work under the hood.
• When you build custom UIs with animations, you'll often need to translate, rotate or scale widgets on screen. Matrix transforms are key to understanding how to do this.

We'll also get some practice working with widgets such as Stack, Align, Positioned, AspectRatio, LayoutBuilder, and cover a bit of state management.
