body: <p>I am trying to use facebook auth in myy app with flutter.</p>
  <p>I did all things in documentation.</p>
  <p>also I tried to find solution here but nothing helped me ,for example <a href="https://stackoverflow.com/questions/71337659/unhandled-exception-missingpluginexceptionno-implemen-tation-found-for-method">this post</a> and <a href="https://stackoverflow.com/questions/68257773/unhandled-exception-missingpluginexceptionno-implementation-found-for-method-l">this post</a></p>
  <p>I add this strings.xml :</p>
  <pre><code>&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
  &lt;resources&gt;
      &lt;string name=&quot;facebook_app_id&quot;&gt;xxxxxxxxxxx&lt;/string&gt;
      &lt;string name=&quot;fb_login_protocol_scheme&quot;&gt;fbxxxxxxxxxxxx&lt;/string&gt;
      &lt;string name=&quot;facebook_client_token&quot;&gt;xxxxxxxxxxxxxxxxx&lt;/string&gt;
      &lt;string name=&quot;app_name&quot;&gt;xxxx&lt;/string&gt;
  &lt;/resources&gt;
  </code></pre>
  <p>in AndroidManifest.xml I add this :</p>
  <pre><code>&lt;uses-permission android:name=&quot;android.permission.INTERNET&quot;/&gt; // before application
  
  &lt;meta-data android:name=&quot;com.facebook.sdk.ApplicationId&quot; android:value=&quot;@string/facebook_app_id&quot;/&gt;
  &lt;meta-data android:name=&quot;com.facebook.sdk.ClientToken&quot; android:value=&quot;@string/facebook_client_token&quot;/&gt;
  
  &lt;activity android:name=&quot;com.facebook.FacebookActivity&quot;
              android:configChanges=
                      &quot;keyboard|keyboardHidden|screenLayout|screenSize|orientation&quot;
              android:label=&quot;@string/app_name&quot; /&gt;
          &lt;activity
              android:name=&quot;com.facebook.CustomTabActivity&quot;
              android:exported=&quot;true&quot;&gt;
              &lt;intent-filter&gt;
                  &lt;action android:name=&quot;android.intent.action.VIEW&quot; /&gt;
                  &lt;category android:name=&quot;android.intent.category.DEFAULT&quot; /&gt;
                  &lt;category android:name=&quot;android.intent.category.BROWSABLE&quot; /&gt;
                  &lt;data android:scheme=&quot;@string/fb_login_protocol_scheme&quot; /&gt;
              &lt;/intent-filter&gt;
          &lt;/activity&gt;
  &lt;queries&gt;
          &lt;provider android:authorities=&quot;com.facebook.katana.provider.PlatformProvider&quot; /&gt;
  </code></pre>
  <p>my function :</p>
  <pre><code>final LoginResult result = await FacebookAuth.instance.login();
        if (result.status == LoginStatus.success) {
          accessToken = result.accessToken!;
          isLogined = true;
          final userData = await FacebookAuth.instance.getUserData();   
        } else {
          print(result.status);
          print(result.message);
        }
  </code></pre>
  <p>I get this error <code>[ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: MissingPluginException(No implementation found for method login on channel app.meedu/flutter_facebook_auth)</code></p>
