Facebook login error using Flutter after install (Android) - facebook

Question

I have a problem using the Facebook login in Flutter after installing into an Android device
My app was running fine with my Android device connected by USB (not using a virtual device), but when I build apk and install it using:
flutter build apk
flutter install
I cannot able to login using facebook, It always gives FacebookLoginStatus.error
I m using: flutter_facebook_login: ^1.2.0
I created 2 different facebook apps and the results were the same.
Whats missing? Thanks in advance!
Below is the source code what I have achieved so far:
void initiateFacebookLogin() async {
var facebookLoginResult =
await globals.facebookLogin.logInWithReadPermissions(['email','public_profile']);
print("face result ${facebookLoginResult.status}");
switch (facebookLoginResult.status) {
case FacebookLoginStatus.error:
showWarning('ERRO no login! Por favor, tente novamente!', context);
break;
case FacebookLoginStatus.cancelledByUser:
showWarning('Login cancelado pelo usuário!', context);
break;
case FacebookLoginStatus.loggedIn:
//print("LoggedIn");
var graphResponse = await http.get(
'https://graph.facebook.com/v2.12/me?fields=name,first_name,last_name,email&access_token=${facebookLoginResult
.accessToken.token}');
profile = json.decode(graphResponse.body);
print(profile.toString());
Cadastro.name=profile['name'];
Cadastro.firstName=profile['firstname'];
Cadastro.lastName=profile['lastname'];
Cadastro.email=profile['email'];
Cadastro.id=profile['id'];
findUser(profile['email'],profile['email'],true).then((bool value){
//print("find user $value");
//if(value==false)
// Navigator.of(context).pushNamed(Cadastro.tag);
});
break;
}
}
