Dart is a fully object-oriented, class-based, simple, and clean language. Google’s popular mobile framework, Flutter uses Dart language to implement high-quality native applications, so it’s recommended that you understand Flutter before beginning this course.

In this course, you will dive deep into Dart 2 language features while using interactive hands-on code playgrounds. This course will help you become confident with Dart extensions, enums, mixins, generics, libraries, asynchronous programming, class variables, callable classes, and generator functions.

By the end of this course, you will have a strong understanding of Dart principles, and you’ll be ready to start using this powerful language in your own projects.

# Error handling - `Future` API

`Future` API uses chaining to handle exceptions. The error is caught and handled in a `catchError()` block. The `catchError()` is chained with the `then()` method.

Calling the asynchronous function `makeDataCall()` from `main()`.

This lesson will help with handling errors and exceptions in Future API.
