[Bug]: Missing plugin exception in web release

[firedotguy]

Platform

Web

Plugin

package_info_plus

Version

9.0.0

Flutter SDK

3.35.2

Steps to reproduce

1. Add package info plus to dependencies
2. Call packageInfo.fromPlatform() after init
3. Build web app (flutter build web --release)

Code Sample

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


void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  runApp(const MainApp());
}

class MainApp extends StatefulWidget {
  const MainApp({super.key});

  @override
  State<MainApp> createState() => _MainAppState();
}

class _MainAppState extends State<MainApp> {
  String version = 'unknown';

  void _getVersion() async {
    final PackageInfo info = await PackageInfo.fromPlatform();
    version = info.version;
    setState(() {});
  }

  @override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addPostFrameCallback((_){
      _getVersion();
    });
  }

  @override
  Widget build(BuildContext context) {
    return Text(version);
  }
}
