Dependencies

firebase_ml_vision: ^0.7.0+2
flutter_camera_ml_vision: ^2.0.0

Here's my code

mlScannerTest.dart

import 'package:flutter/material.dart';
import 'package:flutter_camera_ml_vision/flutter_camera_ml_vision.dart';
import 'package:firebase_ml_vision/firebase_ml_vision.dart';

class MLScannerPage extends StatefulWidget {
  MLScannerPage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MLScannerPageState createState() => _MLScannerPageState();
}

class _MLScannerPageState extends State<MLScannerPage> {
  String _code;
  StatefulWidget _camML;
  bool _startCamera = true;
  bool _resultSent = false;
  final _scanKey = GlobalKey<CameraMlVisionState>();

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

  @override
  Widget build(BuildContext context) {
    _camML = _startCamera
        ? CameraMlVision<List<Barcode>>(
            key: _scanKey,
            detector: FirebaseVision.instance.barcodeDetector().detectInImage,
            onResult: (List<Barcode> barcodes) {
              if (_resultSent || !mounted) {
                return;
              }
              _resultSent = true;

              setState(() {
                _code = barcodes.first.displayValue;
              });
            })
        : null;

    return Scaffold(
      appBar: AppBar(
        title: Text(_code != null && _code.isNotEmpty ? _code : 'None'),
      ),
      body: SizedBox.expand(
        child: _camML,
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          setState(() {
            _startCamera = !_startCamera;
            _resultSent = false;
          });
        },
        tooltip: 'Code',
        child: Icon(Icons.add),
      ),
    );
  }
}

main.dart

import 'package:flutter/material.dart';
import 'package:hits/mlScannerTest.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MLScannerPage(title: 'Flutter Demo Home Page'),
    );
  }
}

So basically, the preview was shown. But no detection whatsoever.

This is not related with vendor.camera.aux.packagelist.

in your log you have this
I/flutter (25094): Bad state: No element, #0 List.first (dart:core/runtime/libgrowable_array.dart:216:5)
this is because barcodes can be empty or null so you have to check it on your side.

Thanks for reminding the check, but it still didn't work even after I add a safeguard before accessing barcodes.first.displayValue

The safeguard : if (barcodes == null || barcodes.length == 0) return;

The error still there, but without the I/flutter (25094): Bad state: No element, #0 List.first (dart:core/runtime/libgrowable_array.dart:216:5)

ok i figured out the problem (this don't block you on using the package) are from the camera plugins and we don't have the hand on it. Maybe you could open an issue for it here.
And my bad it's not a duplicate of #9

EDIT: this doesn't seems to be linked with the camera plugin but an hardware problem. I also got this message but the package is working.

We will close this since we can't do something on this part we are just using the camera plugin and the firebase_ml_vision plugin together. No native code is involved on our side.
