I think it’s rare to encounter this error because I found no one that had the same issue, so let me explain hoping I find the solution here.

I need to open a security camera stream (rtsp) in my app, and I am able to do that when running the app in debug mode (flutter run). Although I encounter the same error, it still works. But if I run the app in release mode, it instantly crashes the app and it closes.

Here’s my code:

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

class StreamingScreen extends StatefulWidget {
  final String streamUrl;
  const StreamingScreen({Key? key, required this.streamUrl}) : super(key: key);

  @override
  State<StreamingScreen> createState() => _StreamingScreenState();
}

class _StreamingScreenState extends State<StreamingScreen> {
  late VlcPlayerController _controller;
  bool isFullScreen = false;
  bool isLoading = true;

  @override
  void initState() {
    super.initState();
    _controller = VlcPlayerController.network(
      widget.streamUrl,
      autoPlay: true,
      hwAcc: HwAcc.full,
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Live streaming'),
        centerTitle: true,
      ),
      body: Center(
        child: Stack(
          children: [
            Column(
              mainAxisAlignment: MainAxisAlignment.center,
              children: [
                Expanded(
                  child: VlcPlayer(
                    controller: _controller,
                    aspectRatio: 16 / 9,
                    placeholder: const Center(
                      child: CircularProgressIndicator(),
                    ),
                  ),
                ),
              ],
            ),
          ],
        ),
      ),
    );
  }

  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }
}

Part of the error:

E/flutter (10296): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: LateInitializationError: Field '_viewId@1174035241' has not been initialized.

I tried many solutions I found, and most of them suggested from ChatGPT, but nothing worked since this view id field is in the package code.
