what is the difference between named funtion and anonymous function with an example widget in dart file?

• A function is a reusable part of a program.
• In this tutorial we will be discussing about anonymous and normal functions in flutter.
• A normal function is a function which has name where as anonymous function does not have.

• Below is an example of creating a button and executing a normal function after clicking the button with out using anonymous function.

  import 'package:flutter/material.dart';
  void main() {
  runApp(MyApp1());
  }
  class MyApp1 extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
  return MaterialApp(
    home: Scaffold(
      appBar: AppBar(
        title: Text('Normal function Example'),
      ),
      body: RaisedButton(
          child: Text("Normal Function"), onPressed: normalFunctionExample),
    ),
  );
  }
  }
  normalFunctionExample() {
  print('Normal function executed');
  }

  Output:

• Anonymous function is a function which has no name.
• Below is an example of creating a button and executing a function after clicking the button using anonymous function

import 'package:flutter/material.dart';
void main() {
  runApp(MyApp1());
}
class MyApp1 extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Anonymous function Example'),
        ),
        body: Column(
          children: <Widget>[
            RaisedButton(
                child: Text("Anonymous function using Arrow function"),
                onPressed: () =>
                    print("welome to kodeazy.com using Arrow functions")),
            RaisedButton(
                child: Text("Anonymous function with out using Arrow function"),
                onPressed: () {
                  print("welome to kodeazy.com without using arrow functions");
                }),
          ],
        ),
      ),
    );
  }
}

Output:
