Flutter Signals Made Easy: Part 1— Introducing signal() and Watch()

Happy coding, Flutter fans! And welcome to an introduction to the signals package for state management.

This is a short an introduction to the Signals library for state management in Flutter. If you want to simplify your code and eliminate the nested verbosity of the default state management that comes with Futter then please read on. I got tho this library after trying:

• InheritedWidget
• Provider
• Riverpod
• BLoC
• RxDart
• Others

In a future article I will give you a summary of each and the pros and cons I found (with examples of course).

But I found Signals outstanding for its simplicity. Read on!

Signals and slots are language constructs for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code. The concepts come from the C++ environment. In Flutter you normally use ValueNotifier and ValueListenableBuilder which come with Flutter and don’t require additional packages. But as we will see signals has less verbosity and less boilerplate, and when it comes to programming “less is more.”
