Unable to Initialize Plugin

Describe the bug

On app startup, plugin returns this in the console. Unhandled Exception: MissingPluginException(No implementation found for method initialize on channel dexterous.com/flutter/local_notifications)
E/flutter (17502): #0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:157:7)
E/flutter (17502):
E/flutter (17502): #1 FlutterLocalNotificationsPlugin.initialize (package:flutter_local_notifications/src/flutter_local_notifications.dart:103:9)
E/flutter (17502):
E/flutter (17502): #2 main (package:med_rpm/main.dart:143:5)
E/flutter (17502):

I have been using this code for over a year and haven't changed anything here. The plugin has been working just fine.
To Reproduce

1. Build app
2. See error

Expected behavior

Normally, the plugin initializes and the app starts. But I can't even get to the main screen in my app since the plug in fails to initialize.

Sample code to reproduce the problem

This is from my main.dart:

if (UniversalPlatform.isAndroid || UniversalPlatform.isIOS) {
///////////////////// More local notification initialization ////////////////////////////
// needed if you intend to initialize in the main function
WidgetsFlutterBinding.ensureInitialized();
// NOTE: if you want to find out if the app was launched via notification then you could use the following call and then do something like
// change the default route of the app
// var notificationAppLaunchDetails =
// await flutterLocalNotificationsPlugin.getNotificationAppLaunchDetails();

var initializationSettingsAndroid =
    AndroidInitializationSettings('app_icon');
var initializationSettingsIOS = IOSInitializationSettings(
    onDidReceiveLocalNotification:
        (int id, String title, String body, String payload) async {
  didReceiveLocalNotificationSubject.add(ReceivedNotification(
      id: id, title: title, body: body, payload: payload));
});
var initializationSettings = InitializationSettings(
    initializationSettingsAndroid, initializationSettingsIOS);
await flutterLocalNotificationsPlugin.initialize(initializationSettings,
    onSelectNotification: (String payload) async {
  if (payload != null) {
    print('local notification payload: $payload');
    appOpenedFromLocalNotification = true;

The bug report template requires a link to a repository that can reproduce the problem. The steps you've described don't indicate much as it would imply the plugin completely fails and if so, would be a more widely reported problem. The example app within the repo still builds fine as well. If your code hasn't changed from when it was working then it's likely your issue with your dev environment. That's something that could've changed and not something I can help with

Thank you. My apologies.
