Unhandled exception: MissingPluginException(No implementation found for method readQRCode on channel qrcode_reader)

See original GitHub issue

Hello,

I’ve been running the library in an app on my Nexus 6 and it has been working fine, except for once when it gave me the following error:

08-10 14:52:36.099 18253-18471/com.londonsockcompany.sockspotter E/flutter: [ERROR:topaz/lib/tonic/logging/dart_error.cc(16)] Unhandled exception: MissingPluginException(No implementation found for method readQRCode on channel qrcode_reader) #0 MethodChannel.invokeMethod (package:flutter/src/services/platform_channel.dart:278:7) <asynchronous suspension> #1 QRCodeReader.scan (package:qrcode_reader/QRCodeReader.dart:67:27) <asynchronous suspension> #2 CorrectSockState.build.<anonymous closure> (package:sock_spotter/components/correct_sock.dart:54:30) #3 _InkResponseState._handleTap (package:flutter/src/material/ink_well.dart:494:14) #4 _InkResponseState.build.<anonymous closure> (package:flutter/src/material/ink_well.dart:549:30) #5 GestureRecognizer.invokeCallback (package:flutter/src/gestures/recognizer.dart:102:24) #6 TapGestureRecognizer._checkUp (package:flutter/src/gestures/tap.dart:161:9) #7 TapGestureRecognizer.acceptGesture (package:flutter/src/gestures/tap.dart:123:7) #8 GestureArenaManager.sweep (package:flutter/src/gestures/arena.dart:156:27) #9 _WidgetsFlutterBinding&BindingBase&GestureBinding.handleEvent (package:flutter/src/gestures/binding.dart:147:20) #10 _WidgetsFlutterBinding&BindingBase&GestureBinding.dispatchEvent (package:flutter/src/gestures/binding.dart:121:22) #11 _WidgetsFlutterBinding&BindingBase&GestureBinding._handlePointerEvent (package:flutter/src/gestures/binding.dart:101:7) #12 _WidgetsFlutterBinding&BindingBase&GestureBinding._flushPointerEventQueue (package:flutter/src/gestures/binding.dart:64:7) #13 _WidgetsFlutterBinding&BindingBase&GestureBinding._handlePointerDataPacket (package:flutter/src/gestures/binding.dart:48:7) #14 _invoke1 (dart:ui/hooks.dart:134:13) #15 _dispatchPointerDataPacket (dart:ui/hooks.dart:91:5)

It happened in the middle of a presentation (never do a live demo!) but hasn’t occurred since. Any idea what happened? Can I provide any more debug info? It has been working fine on a Pixel XL and iPhone X.

Thanks
