We continue with the guys at Dart, in this short article will show the code that we use later in the following article, it’s some guys with a small hierarchy and some variables:
class Mammal {}
class Cow extends Mammal { String moo() => 'moo!'; }
class Pig extends Mammal { String oink() => 'oink!'; }
Mammal mammal = new Mammal();
Cow cow = new Cow();
Pig pig = new Pig();

The instance creation expressions are based on interfaces and minimizes the need fordependency injection.
Example of use of factory:
interface Person factory PersonFactory{
Person(name);
final name;
}
class PersonFactory{
factory Person(name){
if(name== null) return const Ghost();
return new RealPerson(name);
}
}
class RealPerson implements Person{
RealPerson(this.name);
final name;
}
class Ghost implements Person{
const Ghost();
get name() => "ghost";
}
main(){
print(new Person("Pepita") is RealPerson);
print(new Person(null) is Ghost);

This post is a continuation of our two previous articles, if you do not understand something, maybe you should consult they (Part 1, Part 2). It’s inspired on the Chris Buckett’s example.
We will create a simple form to collect name and surname and greet to our visitors. We will create the form dynamically using constructors. We will use an event to capture the button clicked event and we will show a text into a div for our greeting.
This is the structure of the example:
client/client.html – Page with reference to our script, nothing more.
