Dart is an open source class based, object oriented,
optionally typed programming language that assists us
with the development of browser based one page web
applications.
●
We can execute the code that should run on the client
side either by using a web browser that supports Dart or
by compiling our code into JavaScript.

Introduction

4. ●
We can execute our code on the server side by using the
Dart virtual machine.
●
The syntax seems familiar both to those who are used to
JavaScript and to those who are used to JavaPHPC#.
LifeMichael.com
Introduction

5. ●
The Dart programming language bridges the gap between the
JavaScript dynamic type system and the JavaC# static one.
●
The optional typing is available in variable declarations, function
parameters definitions and function return types.
void main()
{
int a = 4;
int b = 3;
var temp = a + b;
print("temp=$temp");
}

Optional Typing

6. ●
The Dart programming language uses classes and interfaces
●
similarly to Java, C# and PHP.
●
Dart supports single inheritance similarly to Java, C# and PHP.
●
Dart supports multiple interfaces implementation similarly to
Java, C# and PHP.
●
Similarly to Java, PHP and C# every class inherits (either
directly or indirectly) from the Object class.
LifeMichael.com
Object Oriented Programming

7. ●
The classes can have public and private members. The
public accessibility is the default one.
●
Dart supports a special shorthand syntax for accessing
class properties, similarly to properties in C#

Object Oriented Programming

8. class Rectangle
{
double _width;
double _height;
Rectangle(double w,double h)
{
width = w;
height = h;
}
get width => _width;
set width(size) => (size>0)?_width=size:_width=10.0;
get height => _height;
set height(size) => (size>0)?_height=size:_height=10.0;
area() => width * height;
perimeter() => 2*(width+height);
}

Object Oriented Programming

9. main()
{
var ob = new Rectangle(3.2,4.4);
ob.width = 20.2;
ob.height = -4.1;
var area = ob.area();
print("area is $area");
}

Object Oriented Programming

10. ●
We can pass a function as an argument to another
function and we can assign a function to a variable.
●
The possibility to define anonymous functions and pass
them over as arguments to other functions simplifies the
code.
LifeMichael.com
Functional Programming

11. goodMorning(str) => print("Good Morning $str");
goodEvening(str) => print("Good Evening $str");
loop(func,name)
{
for(var i=1;i<=3;i++)
{
func(name);
}
}
main()
{
var myFunc = goodEvening;
loop(myFunc,"Danidin");
}

Functional Programming

12. ●
Dart allows us to interact with other parts of the web
document as the DOM and other code written in
JavaScript.
LifeMichael.com
JavaScript Interoperability

13. import 'dart:html';
void main() {
var ob = query("#sample_text_id");
ob.text = "Press Here";
ob.on.click.add(reverseText);
}
void reverseText(Event event) {
var text = query("#sample_text_id").text;
var buffer = new StringBuffer();
for (int i = text.length - 1; i >= 0; i--) {
buffer.add(text[i]);
}
query("#sample_text_id").text = buffer.toString();
}

JavaScript Interoperability

14. ●
Pub is Dart package manager. Pub assists us reusing
existing Dart code.
●
Pub handles versioning and dependency management
and ensures that our application runs on other machines
exactly as it runs on ours.

Dart Package Manager

15. ●
Dart was announced on October 12th 2011. The
developers of Dart seem to learn well from Java
mistakes (waiting with the production release, proper
development tools and neutralizing competitors).
●
During the past two years its development goes side by
side with the development of new Google powered
JavaScript libraries, such as AngularJS and Polymer.

Dart Evolution

16. “The growth of Dart might take us backward to the days
of proprietary vendor lock-in"
“There is a fragmentation risk in the evolution of a new
non standard programming language for the web"
“The optional typing damages the quality of the code"
