export="false" causing exception in vs code

[MuhammamdArslanKhan]

why we are exporting false in provider? what is the reason? Here is my Menifest,

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.mog" xmlns:tools="http://schemas.android.com/tools">
	<uses-permission android:name="android.permission.CAMERA" />
	<uses-permission android:name="android.permission.INTERNET" />
	<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
	<application android:name="io.flutter.app.FlutterApplication" android:label="mokoo_dog" android:icon="@mipmap/ic_launcher">
		<meta-data android:name="com.google.android.geo.API_KEY" android:value="AIzaSyDlws99uIlKKmMTuo443NXa8RNUO7L4vLw" />
		<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id" />
		<provider android:name="com.facebook.FacebookContentProvider" android:authorities="com.facebook.app.FacebookContentProvider457320668485189" android:exported="false"/>
		<activity android:name=".MainActivity" android:launchMode="singleTop" android:theme="@style/LaunchTheme" android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode" android:hardwareAccelerated="true" android:windowSoftInputMode="adjustResize">
			<meta-data android:name="io.flutter.app.android.SplashScreenUntilFirstFrame" android:value="true" />
			<intent-filter>
				<action android:name="android.intent.action.MAIN" />
				<category android:name="android.intent.category.LAUNCHER" />
			</intent-filter>
		</activity>
	</application>
</manifest>

Herer is exception

D:\Mobile\Flutter Projects\moo\android\app\src\debug\AndroidManifest.xml:15:143-167 Error: Attribute provider#com.facebook.FacebookContentProvider@exported value=(false) from AndroidManifest.xml:15:143-167 is also present at [:flutter_share_me] AndroidManifest.xml:13:13-36 value=(true). Suggestion: add 'tools:replace="android:exported"' to element at AndroidManifest.xml to override.

It works fine when removed "export=false" and add "tools:replace="android:authorities"

I am not sure. This is my manifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

         flutter needs it to communicate with the running application
         to allow setting breakpoints, to provide hot reload, etc.

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

    <!-- 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. -->
