The document introduces the Dart programming language, highlighting its open-source, performance-oriented, and modular nature, making it easy to learn and suitable for creating both simple scripts and complex applications. It covers basics like optional types, main function usage, and various object-oriented concepts such as cascade operators, named constructors, and getters/setters. For practical learning, it references a code lab available on GitHub.

1. Introduction to the
Dart lang
Jana Moudrá | @Janamou | +JanaMoudrá

2. Open-source
For better performance
Easy to learn
Object oriented
Modular

3. Use the Dart language,
libraries, and tools to write
anything from simple scripts
to full-featured apps.

9. How?
Learn the language It is easy!

10. Optional Types
var x = 10;
var y = 20;
or
num x = 10;
num y = 20;

11. void main() {
print("Hello world Dart!");
}
main() function

12. void main() {
querySelector("#my-button")
..text = "Open Window"
..onClick.listen(openWindow);
}
Cascade operator

13. class Person {
String firstName;
String lastName;
int age;
Person(this.firstName, this.lastName);
}
void main() {
Person person = new Person("Jana", "Moudrá");
}
Syntactic sugar

14. class Person {
String firstName;
String lastName;
int age;
Person(this.firstName, this.lastName);
Person.withAge(this.lastName, this.age);
}
void main() {
Person person = new Person.withAge("Moudrá", 25);
}
Named constructors

15. class Person {
String _firstName;
String _lastName;
int _age;
Person(this._firstName, this._lastName);
Person.withAge(this._lastName, this._age);
int get age => _age;
set age(int age) => _age = age;
}
Getter and Setter

16. How?
Develop awesome apps!
