Edit android manifest correctly

I'm trying to use the flutter_foreground_plugin for my project but I'm having difficulty understanding how to edit the android manifest file.
these are the required edits:
These are my interpretations of said edits:
What am I doing wrong? I get the error
error: FlutterForegroundPlugin() has private access in FlutterForegroundPlugin
flutterEngine.getPlugins().add(new changjoopark.com.flutter_foreground_plugin.FlutterForegroundPlugin());

Open FlutterForegroundPlugin.java
change from private FlutterForegroundPlugin() {} to public FlutterForegroundPlugin() {}

This AndroidManifest.xml can help you how to configure your project.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="changjoopark.com.flutter_foreground_plugin_example"
xmlns:tools="http://schemas.android.com/tools">
<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
<!-- io.flutter.app.FlutterApplication is an android.app.Application that
calls FlutterMain.startInitialization(this); in its onCreate method.
In most cases you can leave this as-is, but you if you want to provide
additional functionality it is fine to subclass or reimplement
FlutterApplication and put your custom class here. -->
<application
android:name="io.flutter.app.FlutterApplication"
android:label="Flutter ForegroundService Example"
android:icon="#mipmap/ic_launcher">

android:hardwareAccelerated="true"
android:windowSoftInputMode="adjustResize">
<!-- This keeps the window background of the activity showing

there is no splash screen (such as the default splash screen
defined in #style/LaunchTheme). -->
<meta-data

</application>
<uses-sdk
android:minSdkVersion="23"
tools:overrideLibrary="changjoopark.com.flutter_foreground_plugin" />
</manifest>
You can also try to download this example and try to run it on your machine so you can clear your doubts.
Thank you.

what is the problem?
You commented out android.intent.action.MAIN action of your intent filter (docs).

Flutter: Schedule notification not working

I am developing a app using Flutter.
To show notification I an using flutter_local_notifications package.
I am getting notification, but schedule notification is not working.
Similar question was asked here How do I schedule a notification in Flutter?, but my receiver is already inside the application tag.
Here is my manifest
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.folk.gayatrimonitor">
<!-- The INTERNET permission is required for development. Specifically,
flutter needs it to communicate with the running application
to allow setting breakpoints, to provide hot reload, etc.
-->

<uses-permission android:name="android.permission.VIBRATE" />

<uses-permission android:name="android.permission.WAKE_LOCK"/>

adding this inside application of your manifest might solve your problem
<service android:name="com.folk.localnotifications.services.LocalNotificationsService"
android:exported="false" />
Remember: com.folk is used for this project only. For different project, go to your manifest, see package name and edit accordingly.

I had the same problem but couldn't find the solution online, however, later I did figure out running flutter clean then flutter run seems to do the trick for me.
You have to essentially clean your build and rebuild it again. Hope that helps.

I had the same issue, I solved it by creating a separate notification channel for each android notification I was issuing, even if they share the same priority.

In my case, I just added the following inside initState()
var initializationSettingsAndroid =
AndroidInitializationSettings('#mipmap/ic_launcher');
var initializationSettingsIOS = IOSInitializationSettings();
var initializationSettings = InitializationSettings(
android: initializationSettingsAndroid, iOS: initializationSettingsIOS);
flutterLocalNotificationsPlugin.initialize(
initializationSettings,
);

Launching app from HomeScreen (shortcut) and from App drawer, is not the same

I've encountered a weird behaviour. Maybe someone could clarify it.
When I download my app from GooglePlay, there are 2 icons that are added. One goes to the Home Screen as a shortcut and another goes to the App Drawer (the screen with all the different installed apps I got on my device).
Now here is the flow of events:
I install the app from GooglePlay
I launch the app once installation is complete, also from GooglePlay (There's an open button) --> This launches the app, shows a splash screen and goes to my main screen
I navigate around in my app to a different screen
I click the home button to go to the Home Screen.
Now the interesting part:
I press the Home Screen shortcut icon GooglePlay has created for me to get back to my app --> This takes me to the exact same screen I was in.
I click the home button again to go to the Home Screen.
This time, I press the App Drawer shortcut icon to get back to my app --> This shows the splash screen again and takes me to my main screen.
This happens constantly. Each shortcut launches to a different state (or screen).
Notice that there is only one app in the Recent list.
On a the other hand. If I create the Home Screen shortcut myself, I get the same results when I launch the app from both icons.
Something is different with the shortcut GooglePlay is creating for me.
Any ideas?

I am sorry to tell you that this is not a bug in your project but an android default behaviour. I did some research ending up in the following threads. Maybe you can filter out some useful information and test these approaches in your project.
App completely restarting when launched by icon press in launcher
Android application restarts when opened by clicking the application icon
