Classes, Constructors, and Objects - Flutter | Dart ~ Episode 1.6
Hey Coders! This one is going to be a slow burn. The topic of classes is extremely important in your journey of programming with Dart and Flutter, but it is also an extremely vast topic, and it can also be very hard to understand at times. Think of it like this: classes are the blueprint for creating your user-defined objects. Every time you want to make a new instance of your object, your code will reference its respective class. Classes are broken into four sections: the instance variables, the getter/setter methods, the constructor, and the methods. We'll do a cursory overview of all of these important sections, along with a quick look at inheritance in this video!
