Hi,

i got these errors on Production

java.lang.RuntimeException: at android.app.ActivityThread.deliverResults (ActivityThread.java:4493) at android.app.ActivityThread.handleSendResult (ActivityThread.java:4537) at android.app.ActivityThread.-wrap21 (Unknown Source) at android.app.ActivityThread$H.handleMessage (ActivityThread.java:1813) at android.os.Handler.dispatchMessage (Handler.java:106) at android.os.Looper.loop (Looper.java:192) at android.app.ActivityThread.main (ActivityThread.java:6831) at java.lang.reflect.Method.invoke (Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run (RuntimeInit.java:438) at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:825) Caused by: java.lang.IllegalStateException: at io.flutter.view.FlutterNativeView$PlatformMessageHandlerImpl$1.reply (FlutterNativeView.java:197) at io.flutter.plugin.common.MethodChannel$IncomingMethodCallHandler$1.success (MethodChannel.java:204) at com.apptreesoftware.barcodescan.BarcodeScanPlugin.onActivityResult (BarcodeScanPlugin.kt:43) at io.flutter.app.FlutterPluginRegistry.onActivityResult (FlutterPluginRegistry.java:210) at io.flutter.app.FlutterActivityDelegate.onActivityResult (FlutterActivityDelegate.java:143) at io.flutter.app.FlutterActivity.onActivityResult (FlutterActivity.java:142) at android.app.Activity.dispatchActivityResult (Activity.java:7431) at android.app.ActivityThread.deliverResults (ActivityThread.java:4489)

And the exact line causing the error is this line right here

barcode?.let { this.result?.success(barcode) }

any ideas how this could happen?
