mlkit_scanner package conflicts with google_mlkit_text_recognition package

[panksi]

Hi all,
thanks for the efforts in making this package.
I started working on the app which uses this scanner a month ago. this package was one of the first that I initialized and tested as a widget to make sure I can use it when I need it. I used the example you pointed out and Initialized the BarcodeScanner Widget accordingly. However, now when I got back to it to actually use it (or let's say join with the rest of the screens in the app) It just keeps crashing. First I taught it's the "clash" between google_ml_kit and mlkit_scanner packages, but now, as I ended up trying to init the page with mlkit_scanner directly as a child class of MyApp (main) widget:

In my main.dart file I did this

class MyApp extends StatelessWidget {
  const MyApp(
      {
      Key? key})
      : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'testapp',
      theme: theme,
      home: const ScanQRCodePage(),
    );
  }
}

in scan QR code page I did this:

import 'package:flutter/material.dart';
import '../ui/helpers/animations_helper.dart';
import 'package:mlkit_scanner/mlkit_scanner.dart';
import './connect_bluetooth_page.dart';

class ScanQRCodePage extends StatefulWidget {

  const ScanQRCodePage({super.key});

  @override
  State<ScanQRCodePage> createState() => ScanQRCodePageState();
}

class ScanQRCodePageState extends State<ScanQRCodePage> {
  BarcodeScannerController? barcodeScannerController;
  String _imei = '';

  @override
  Widget build(BuildContext context) => Scaffold(
      appBar: AppBar(title: const Text('Scan QR Code')),
      body: Column(
        children: [
          Container(
            padding: const EdgeInsets.all(24),
            child: Text('scan QR code page $_imei'),
          ),

          Expanded(
            flex: 10,
            child: BarcodeScanner(
                cropOverlay: const CropRect(scaleHeight: 0.2, scaleWidth: 0.3),
                onScannerInitialized: (cntr) => _onScannerInitialized(cntr),
                onScan: (code) {

                  if (code.length == 15) {
                    setState(() {
                      _imei = code;
                    });

                    barcodeScannerController?.cancelScan();

                    Navigator.push(
                      context,
                      CustomPageRoute(
                          builder: ConnectBluetoothPage(imei: _imei),
                          direction: AxisDirection.right),
                    );
                  }
                },
                onCameraInitializeError: (error) {
                  print('ERROR ON CAMERA ' + error.toString());
                }),
          )
        ],
      ));

  Future<void> _onScannerInitialized(
      BarcodeScannerController? controller) async {
    if (controller == null) {
      print('Controller is null, terminating');
      return;
    }
    setState(() {
       barcodeScannerController = controller;
    });
    await barcodeScannerController.startScan(100);
  }
}

This is the Debug log:

UPDATE: As I wanted to make sure that the issue truly exists I just copy-pasted the example to my project in order to see if it works. When I hit the startScan button the app just crashes. the only thing in debug log is this:
I/Process (12983): Sending signal. PID: 12983 SIG: 9
Lost connection to device.
Exited (sigterm)

UPDATE 2: I created a completely new project with mlkit_scanner and it worked. Got back to my project and commented out google_mlkit_text_recognition package and now it worked in my project also. This basically means: mlkit_scanner conflicts with google_mlkit_text_recognition. This is as far as I go, hope you find out what's the issue here. good luck.

@panksi have you get a solution?

@panksi have you get a solution?

I just switched to google_mlkit_scanner package which is a part of google_mlkit bundle and it worked well with it.
