Flutter Android ERROR: ensureInitializationComplete must be called after startInitialization

Currently I'm trying to add a flutter app to my android app but when I try to do an Intent the app crashes and prints the following issue:
I followed this guide here
I get this error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.testappandroid/io.flutter.embedding.android.FlutterActivity}: java.lang.IllegalStateException: ensureInitializationComplete must be called after startInitialization

So it says: ensureInitializationComplete must be called after startInitialization. One solution is to call FlutterMain.startInitialization(this) in the Flutter Activity. But this isn't working for me:
My Flutter Activity:
public class MainActivity extends FlutterActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
FlutterMain.startInitialization(this);
super.onCreate(savedInstanceState);
GeneratedPluginRegistrant.registerWith(this);
}
}

</manifest>
With this line of code I try to open the FlutterActivtiy. This is calling the main() function in my dart code:
Intent defaultFlutter = createDefaultIntent(activity);
activity.startActivity(defaultFlutter);
The code above should start this:
void main() => runApp(MaterialApp(
routes: {
"/": (context) => TestWidget()
}
));
So I followed step by step the guide for adding Flutter to an existing android app. Do I forget something? In my mind maybe the AndroidManifest of the flutter app needs some changes? Any ideas what I'm doing wrong?

insure that you import the right packages:
import io.flutter.embedding.android.FlutterActivity;
import io.flutter.embedding.engine.FlutterEngine;
instead of
import io.flutter.app.FlutterActivity
in your MainActivity so your Main activity should look like this:
package com.example.example
import io.flutter.embedding.android.FlutterActivity;
import io.flutter.embedding.engine.FlutterEngine;
class MainActivity: FlutterActivity() {
}

FlutterMain.startInitialization(this);
Add This Line Before Super.Create like
FlutterMain.startInitialization(this) //Added line
super.onCreate(savedInstanceState)
GeneratedPluginRegistrant.registerWith(this)

Despite the message ensureInitializationComplete must be called after startInitialization, it is not required to call it. Run Flutter activity this way:
FlutterMain.startInitialization(context)
startActivity(FlutterActivity.createDefaultIntent(context))
If you get the crash NoClassDefFoundError (class DefaultLifecycleObserver), add this dependency to your android module:
implementation 'android.arch.lifecycle:common-java8:1.1.0'

</application>
I think it has something to do with the Theme but can't figure it out.

In your res/values/style.xml the style AppTheme should be a Theme.AppCompat theme. For example:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
Also make sure you are importing the android appcompat library in your app/build.gradle file.
dependencies {
implementation "com.android.support:appcompat-v7:27.1.1"
}

And also i dont understand why initialization of SDK is not actual and it stroked. I have tried solutions which on stack. Doesn't help.
Also if any1 know the good example where Firebase and Facebook auth integrated well? Because as always firebase guide is totally collapsed my brain.

You need add
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//initialize Facebook SDK
FacebookSdk.sdkInitialize(getApplicationContext());
if (BuildConfig.DEBUG) {
FacebookSdk.setIsDebugEnabled(true);
FacebookSdk.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
}
setContentView(R.layout.activity_main); }
Need add meta-data to Application
<application android:label = "#string/app_name" ... >
...
<meta-data android:name = "com.facebook.sdk.ApplicationId" android:value = "#string/facebook_app_id" />
...
</ application>
instead of
<activity android:name=".FacebookLoginActivity"
>
<meta-data android:name="com.facebook.sdk.ApplicationId"
android:value="#string/facebook_app_id"/>
</activity>

You don't really need to initialize FacebookSDK manually as it gets initialized automatically, just change your manifest file as #Boris showed. Hope it will work now.

COSU: Cannot find Activity any more after pin and then restart

I'm developing an App that can be Screen Pinned aka Corporate Owned Single Use aka Lock Task Mode.
If I pin it and then:
I close it (killing it) and then I launch it again
or after some code modification in android studio and then perform Run
restart after pin and unpin
I get the following error:

If I don't ever pin the app I can restart/upgrade&run it many times I want.
The nice thing is that is not even possible to uninstall the app because it has been configured as Device Owner, and so, it cannot be uninstalled unless a factory reset.
I dont understand how is possible that my activity disappears after an app restart. Can be something related to the intent category or action?
If anyone else encountered this behavior can tell me I will submit an issue to the bug report site.
Thanks.
EDIT 18/3
I think maybe this is happening because at a certain point, I kill the home category activity that in my case is the missing StartActivity in question, and it is not restarted even if I restart the app.

Found the solution in my COSU disable pinning implementation, I was doing:
PackageManager mPackageManager = getApplicationContext().getPackageManager();;
mPackageManager.setComponentEnabledSetting(
new ComponentName(getApplicationContext(), StartActivity.class),
PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
PackageManager.DONT_KILL_APP);
to disable the pinning on device boot, but this actually disable the specified component.
The correct implementation would be:
PackageManager mPackageManager = getApplicationContext().getPackageManager();;
mPackageManager.setComponentEnabledSetting(
new ComponentName(getApplicationContext(), StartActivity.class),
PackageManager.COMPONENT_ENABLED_STATE_DEFAULT,
PackageManager.DONT_KILL_APP);
