[Bug]: ERR_FILE_NOT_FOUND: package_info_plus not working on Flutter web deployed as chrome extension

[BirjuVachhani]

Platform

Web (chrome & Edge)

Plugin

package_info_plus

Version

3.0.2 (latest)

Flutter SDK

3.3.10

Steps to reproduce

Run the sample code on flutter web deployed as chrome extension

Deploying as chrome extension:

1. Run flutter build web --release --web-renderer html --csp
2. In Chrome/Edge go to the extensions page (chrome://extensions or edge://extensions).
3. Enable Developer Mode.
4. Load the build/web directory to your browser.
5. Open new tab and check the text.
6. Instead of printing the version on screen, there's an error: FILE_NOT_FOUND in the console and it never shows the version.

If the same thing is done with a normal run of the project with flutter run web then it works perfectly. It just doesn't work on web builds deployed as browser extension.

According to the error in. the console, it seems like the base uri for version.json file is incorrect in this case.

Code Sample

### main.dart


import 'package:flutter/material.dart';
import 'package:package_info_plus/package_info_plus.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: MyWidget(),
        ),
      ),
    );
  }
}

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

  @override
  State<MyWidget> createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> {
  String? version;

  @override
  void initState() {
    super.initState();
    fetchVersion();
  }

  @override
  Widget build(BuildContext context) {
    return Text(
      version ?? 'Loading...',
      style: Theme.of(context).textTheme.headline4,
    );
  }

  Future<void> fetchVersion() async {
    final PackageInfo info = await PackageInfo.fromPlatform();
    setState(() => version = info.version);
  }
}


### web/manifest.json

```json
{
  "name": "Test Project",
  "description": "A is a description.",
  "version": "0.1.1",
  "manifest_version": 3,
  "short_name": "test",
  "content_security_policy": {
    "content_security_policy": {
      "extension_pages": "script-src 'self' ; object-src 'self'"
    }
  },
  "chrome_url_overrides": {
    "newtab": "index.html"
  },
  "icons": {
    "128": "icon128.png"
  }
}

I'm facing the same issue when I deploy a flutter app as a CDN resource, i.e. just a <script> element pointing to an external http url. It turns out the culprit is a window.document.baseUri in method getAll of PackageInfoPlusWebPlugin. Obviously it won't work unless both <script> and <base> elements point to the same source, which in my case is not the point.

It would be nice to have a way to parameterize that baseUri, but I can't think of how it can fit in the platform agnostic interface. If I find a workaround I'll post it here.
