How can I get icon from Google icons by code point?

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: Center(child: Row(children: [
          Text("This is not right icon :"),
          const Icon(IconData(0xe88e, fontFamily: 'Material+Symbols+Outlined:opsz'), size: 40.0, color: Color.fromARGB(255, 253, 183, 6))
        ]) )  
      ),
    );
  }
}

Icon icn = const Icon(IconData(0xe88e, fontFamily: 'Material+Symbols+Outlined:opsz'), size: 20.0, color: Color.fromARGB(255, 253, 183, 6));
