Flutter/Dart - Unhandled Exception: MissingPluginException

Question

I'm trying to access the device microphone on press with the aim of recording a voice-note. I have tried to access the current permission value but get the following error:

    [VERBOSE-2:ui_dart_state.cc(166)] Unhandled Exception: MissingPluginException(No implementation found for method checkPermissionStatus on channel flutter.baseflow.com/permissions/methods)

[VERBOSE-2:profiler_metrics_ios.mm(184)] Error retrieving thread information: (ipc/send) invalid destination port

Here is the code for my screen:

import 'package:flutter/material.dart';
import 'package:audio_recorder/audio_recorder.dart';
import 'package:permission_handler/permission_handler.dart';

class InsideLeft extends StatefulWidget {
  @override
  _InsideLeftState createState() => _InsideLeftState();
}

class _InsideLeftState extends State<InsideLeft> {
  @override
  Widget build(BuildContext context) {
    return Container(

      child: GestureDetector(
        child: Icon(Icons.mic),
        onTap: () async {
          PermissionStatus mic = await Permission.microphone.status;
          print('microphone permission? ${mic.toString()}');
//          try {
////            if (mic != PermissionStatus.granted) {
////              await Permission.microphone.request();
////            }
////          } catch (e) {
////            print(e);
////          }
        },
      ),
    );
  }


}

Any thoughts how to get around this?
