Facebook login error in Flutter - Please follow our document to upgrade to new APIs to avoid overriding onActivityResult() - flutter

Question

Error: You're calling logging in Facebook with an activity supports androidx activity result APIs. Please follow our document to upgrade to new APIs to avoid overriding onActivityResult().
I do not have an MainActivity.java file. Instead I have MainActivity.kt
Here my MainActivity.kt:
package com.***.app
import io.flutter.embedding.android.FlutterFragmentActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugins.GeneratedPluginRegistrant
class MainActivity: FlutterFragmentActivity() {
override fun configureFlutterEngine(flutterEngine:
FlutterEngine) {
GeneratedPluginRegistrant.registerWith(flutterEngine)
}
}
And here my AndroidManifest.xml
<application
android:usesCleartextTraffic="true"
android:requestLegacyExternalStorage="true"
android:label="***"
android:icon="#mipmap/ic_launcher">
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="#string/facebook_app_id"/>
<meta-data android:name="com.facebook.sdk.ClientToken"
android:value="#string/facebook_client_token"/>
<activity android:name="com.facebook.FacebookActivity"
android:configChanges=
"keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="#string/app_name" />
<activity
android:name="com.facebook.CustomTabActivity"
android:exported="true">
<intent-filter>
<action
android:name="android.intent.action.VIEW" />
<category
android:name="android.intent.category.DEFAULT" />
<category
android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="#string/fb_login_protocol_scheme" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
...
This is, how I call the flutter_facebook_auth package login method
flutter_facebook_auth: ^4.4.1+1
import 'package:flutter_facebook_auth/flutter_facebook_auth.dart';
final LoginResult result = await FacebookAuth.instance
.login(permissions: ['name', 'email']);
I followed the steps described here:
https://facebook.meedu.app/docs/4.x.x/android
https://developers.facebook.com/docs/facebook-login/android/?locale=en
https://developers.facebook.com/apps/569466344883647/fb-login/quickstart/

Answer 1

Solved the problem by using flutter_login_facebook instead of flutter_facebook_auth. There where no further changes necessary then that
Thanks to #Bellrampion for the suggestion.
From:
final LoginResult result = await FacebookAuth.instance
.login(permissions: ['name', 'email']);
to
import 'package:flutter_login_facebook/flutter_login_facebook.dart';
class FacebookSignInApi {
// Create an instance of FacebookLogin
static final fb = FacebookLogin();
static login() async {
// Log in
final res = await fb.logIn(permissions: [
FacebookPermission.publicProfile,
FacebookPermission.email,
]);
}
}
