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.

Developing Web Applications with Dart

# Solution: Mixins

Implement a new person named 'student' who likes to sketch doodles, reads term papers, and runs for 5 miles every day.

**Solution #1:** Add a new class for `Student` that implements desired behaviors using `Sketching`, `Reading`, and `Exercise`.
```dart
class Student extends Person with Sketching, Reading, Exercise {
}
```

**Solution #2:** Use Mixins from the [previous lesson](https://www.educative.io/pageeditor/5726865580883968/6427715525672960/5796239615459328) to implement student's behaviors using the following methods: `sketchDoodles()`, `reviewTermPaper()`, and `powerRun()`.

```dart
  //Sketching doodles 
  sketchDoodles() {
    ...
  }

  //reading term paper
  reviewTermPaper() {
    ...
  }
  
  //daily exercise
  powerRun() {
    ...
  }
```
