IconButton in Flutter

The IconButton widget is used to create  icon-based buttons. Typically used for actions that are represented by symbols rather than text.

There Are Some Common Attributes for IconButton

Here's a simple example of using a IconButton in Flutter:

File open lib->main.dart file −

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(
    MyApp()
  );
}
class MyApp extends StatefulWidget{

  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {

  @override
  Widget build(BuildContext context) {
    return   MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          backgroundColor: Colors.blue,
          title: Text('Icon Button Example',
              style:TextStyle(fontSize: 20,color: Colors.white)),
        ),
        body: Center(
          child:
          Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              IconButton(
                icon: Icon(
                  Icons.star,
                  color: Colors.red, // Set the color of the icon
                  size: 70.0, // Set the size of the icon
                ),
                onPressed: () {
                  // Your button press logic goes here
                },
                tooltip: 'Add Ratting', // Tooltip to display on long press
              ),              IconButton(
                icon: Icon(
                  Icons.add_box,
                  color: Colors.blue, // Set the color of the icon
                  size: 70.0, // Set the size of the icon
                ),
                onPressed: () {
                  // Your button press logic goes here

                },
                tooltip: 'Add Product', // Tooltip to display on long press
              ),



            ],
          ),
        )

    ));

  }


}

Open Device Manager, run the emulator, and then run the application. Next, check the working output and check the output you declared in your code.
