I am getting below error while using the barcode scanner with FlutterFragment (works fine with FlutterActivity). 

E  [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)
                                                                                                    #0      InstanceManagerHostApi.clear (package:camera_android_camerax/src/camerax_library.g.dart:315:7)

Hi @frqarshed ,

We are not used to projects embedding Flutter fragment in an Android Activity. Do you have a small project example that we can test on ?

Note that our plugin needs a reference to the Activity. So check that you didn't call .shouldAttachEngineToActivity(false) when creating the fragment.

@ndusart Attached is a minimum sample and steps to reproduce are mentioned in a text file.
