[ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: SocketException: Failed host lookup: 'graph.facebook.com' (OS Error: No address associat ed with hostname, errno = 7)

[DyaryRaoof]

I am trying to implement Facebook login for my flutter app but it doesn't work in android although it works perfectly on iOS. I am using `

flutter_facebook_login 3.0.0

` I have done everything according to the documentation and looked at a lot of stack overflow issues on this to no avail.

i get this error :

[ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: SocketException: OS Error: No route to host, errno = 113, address = graph.facebook.com, port = 42878

I have given both development and production key hashes to Facebook.

also tried to change the login method to Webview only. it doesn't work either.

please guys i have done a lot of searching and i feel helpful. any help is greatly appreciated. thank you.

and Facebook login implementation:

final result =
        await facebookLogin.logIn(["email", "public_profile", "user_friends"]);
    print(result.errorMessage);
    switch (result.status) {
      case FacebookLoginStatus.loggedIn:
        final token = result.accessToken.token;
        final graphResponse = await http.get(
            'https://graph.facebook.com/v2.12/me?fields=name,picture.width(800).height(800),email&access_token=$token');
        final profile = JSON.jsonDecode(graphResponse.body);
