Mastering Concurrent Programming in Dart

In the previous chapters, we explored different design patterns and architecture best practices in Flutter. Now, it’s time to explore another important topic: working with concurrency in Dart.

Flutter is known for catchy taglines such as “Everything’s a Widget” and “Dart is single-threaded.” We have already debunked the former and learned that not everything is a widget as there are also elements and render objects. In this chapter, we will investigate the truth behind the saying “Dart is single-threaded.” We will explore the asynchronous world of Flutter and Dart, understand the peculiarities of their APIs, and learn how to work with them correctly and efficiently.

Concurrency-related concepts are often complex, leading to confusion, misuse, and frustration in programming. However, they are crucial because modern applications and programming languages require concurrency support...
