Dart
What is Dart?
Dart is a client-optimized programming language for apps on multiple platforms. It is developed by Google and is used to build mobile, desktop, server, and web applications. Dart is an object-oriented, class-based, garbage-collected language with C-style syntax. It supports interfaces, mixins, abstract classes, generics, and optional typing.
-
Object-Oriented
- Dart is an object-oriented language, which means that everything in Dart is an object.
- Objects are instances of classes, which are blueprints for creating objects.
-
Class-Based
- Dart is a class-based language, which means that all objects are created from classes.
- Classes are used to define the structure and behavior of objects.
-
Garbage-Collected
- Dart is a garbage-collected language, which means that the Dart VM automatically reclaims memory occupied by objects that are no longer in use.
- This allows developers to focus on writing code instead of worrying about memory management.
Examples
Here are some simple example problems that explore making a coffee.
class CoffeeMaker {
void makeCoffee() {
grindCoffeeBeans();
brewCoffee();
pourInCup();
addCondiments();
}
void grindCoffeeBeans() {
print('Grinding coffee beans');
}
void brewCoffee() {
print('Brewing coffee');
}
void pourInCup() {
print('Pouring coffee into cup');
}
void addCondiments() {
print('Adding condiments');
}
}
Conclusion
Dart is a powerful programming language that can be used to build mobile, desktop, server, and web applications. It is an object-oriented, class-based, garbage-collected language with C-style syntax.
