Welcome to Stackoverflow . Try the following code. Your above code is also correct.

Try to check below line in your pubspec.yaml file

flutter:
  uses-material-design: true

ReferFlutter Icons

Full Example:

import 'package:flutter/material.dart';

void main() {
  runApp(
    MyApp(),
  );
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: Center(
          child: MyWidget(),
        ),
      ),
    );
  }
}

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Center(
      child: Icon(
        Icons.star,
        color: Colors.red,
        size: 100,
      ),
    );
  }
}
