Dart Classes and Widgets Explained in Flutter

Understanding Dart classes and widgets is essential for building scalable Flutter apps. In Dart, everything is an object, and classes are the blueprint to create custom objects that hold data and logic. Widgets in Flutter are the building blocks of the user interface, and many of them are defined using Dart classes.

Here’s a simple example of a Dart class in Flutter:

class Person {
  String name;
  int age;

  Person({required this.name, required this.age});

  void greet() {
    print('Hello, my name is $name and I am $age years old.');
  }
}

In Flutter, you’ll often use StatelessWidget or StatefulWidget as base classes:

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text("Home")),
      body: Center(child: Text("Welcome to Flutter!")),
    );
  }
}

This code creates a simple widget that displays a welcome message. To dive deeper into Dart OOP and Flutter architecture, visit this helpful resource:
