A flutter plugin that allows you to change the app's icons and label in real time.

Description
The bug is an error that is triggered when trying to switch the App Icon. For some personal project reasons, we need to set the main activity name as "io.flutter.embedding.android.FlutterActivity" instead of ".MainActivity".
This makes the package code not recognize either the definitions of the "MainActivity" or "io.flutter.embedding.android.FlutterActivity" class names and throw an exception.
To Reproduce
Expected behavior
The icon switch should work properly.
Logs
Example of the error log when initializing and switching to the "MainActivity" class:
[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: PlatformException(error, Component class com.mypackage.myproject.MainActivity does not exist in com.mypackage.myproject, null, java.lang.IllegalArgumentException: Component class com.mypackage.myproject.MainActivity does not exist in com.mypackage.myproject

Solution
Search for keywords in the project: "DONT_KILL_APP"
Find the MethodCallImplementation.Java file
Find this line.
pm.setComponentEnabledSetting(cn, componentState, PackageManager.DONT_KILL_APP);
Add this code above it.
else{
componentState = PackageManager.COMPONENT_ENABLED_STATE_DISABLED;
}It Work.

Describe the bug
Could you please update the pub.dev package? The current version there creates two launcher icons not one. The current version in your repo is working but not published. Thank you :)
