FAQs on Flutter 7 - Intro to Classes Video Lecture - Flutter: Build beautiful native apps in record time - App Development

1. What is Flutter?
Ans. Flutter is an open-source UI software development kit created by Google. It is used to develop cross-platform applications for mobile, web, and desktop platforms using a single codebase.
2. What is a class in Flutter?
Ans. In Flutter, a class is a blueprint or a template for creating objects. It defines the properties (variables) and behaviors (methods) that an object can have. Classes are used to create reusable components in Flutter app development.
3. How do you create a class in Flutter?
Ans. To create a class in Flutter, you need to define it using the "class" keyword followed by the class name. Inside the class, you can define variables, methods, and constructors. Here's an example of creating a class named "Person": class Person { String name; int age; Person(this.name, this.age); void sayHello() { print("Hello, my name is $name and I am $age years old."); } }
4. What is the purpose of constructors in Flutter classes?
Ans. Constructors in Flutter classes are special methods that are used to initialize the properties (variables) of an object when it is created. They provide a convenient way to set the initial values of variables. In the example above, the constructor "Person(this.name, this.age)" initializes the "name" and "age" variables when a new "Person" object is created.
5. How can classes be used to create reusable components in Flutter?
Ans. Classes in Flutter can be used to create reusable components by encapsulating related properties and behaviors into a single entity. By creating a class for a specific component, such as a button or a card, you can easily create multiple instances of that component with different properties. This promotes code reusability and makes it easier to maintain and update the app.
