The field variables need to be set, but they must also be manipulated before they will be set. With a setter, we can accomplish this. With a getter, we can alternate our value before sending it to the asked object.
- [Narrator] Welcome to the last video…on getters and setters.…In the previous video,…we looked at how you could create a library.…In this video, we're going to take a look…at how to define getters and setters in our classes,…and how we can benefit ourselves from their functionality.…We're going to work with getters and setters,…and for that, we're going to create the field damage…in the encounter class.…Getters and setters are mainly used…to protect the property of a class.…
In the environment class,…we can create a getter…that propagates the value of the field encounter…to the end user when he calls for the damage property.…The arrow in our getter is a shorcut…for the return statement…when everything can be done using a single line.…We can also create a setter in the environment class…for the field name.…First of all, we need to make the field name private…by putting an underscore before the name.…
By default, it is public.…So this our setter for our field name,…so every time the name has been set,…we will put a dash around the name.…
Dart is a new open-source programming language for the web. It is a single language for both client and server that can be used to build large-scale web, server, and mobile applications. Stop solving new challenges with the same old tools—let Dart show you a whole new way! In this course, author Joris Hermans guides you into the wonderful world of web development with the dartlang programming language. By following along, you get a more mature sense of how to build a great application and see all the facets needed to reach that goal.
Learn the important language features of Dart, along with some advanced features such as mixins and null-aware operators. Later on, see how to use unit tests, work with browser APIs, and set up of a web server. Finally, take a look at Angular 2, a great front-end framework also built by Google.
