To Register Cloud Firestore with Facebook Input - firebase

Question

I can log in with Facebook, but I can not register Cloud Firestore. How do I get the resources to suggest? I can log in with Google, but here I have problems. I've shared the codes below. I'm not receiving an error. The information comes from Facebook but clicking on the button on the try catch process:
Future<Kullanici> facebookIleGiris() async {
print("Login wiht facebook");
FacebookLoginResult _result = await _facebookLogin.logIn(['email']);
switch(_result.status){
case FacebookLoginStatus.cancelledByUser:
print("user logout");
break;
case FacebookLoginStatus.error:
print("error");
break;
case FacebookLoginStatus.loggedIn:
await _loginWithFacebook(_result);
break;
}
}
_loginWithFacebook(FacebookLoginResult _result) async {
FacebookAccessToken accessToken = _result.accessToken;
AuthCredential _credential =
FacebookAuthProvider.getCredential(accessToken: accessToken.token);
AuthResult result = await _firebaseAuth.signInWithCredential(_credential);
print('${result.user.uid} ');
print('${result.user.displayName} now login');
print('${result.user.email} ');
print('${result.user.photoUrl} ');
print('${result.user.phoneNumber}');
return _kullaniciOlustur(result.user);
ButtonClick
void _faceIleGiris() async {
print("user clicked");
var _yetkilendirmeServisi = Provider.of<YetkilendirmeServisi>(context, listen: false);
print("user 2. step");
try {
Kullanici kullanici = await _yetkilendirmeServisi.facebookIleGiris();
print("kullanici kontrole başladi ${kullanici.email}");
if (kullanici != null) {
print(" ${kullanici.email}");
Kullanici fireStoreKullanici = await FirestoreServisi().kullaniciGetir(kullanici.id);
if (fireStoreKullanici == null) {
print("user created ${kullanici.email}");
FirestoreServisi().kullaniciOlustur(
id: kullanici.id,
email: kullanici.email,
kullaniciAdi: kullanici.userName,
fotoUrl: kullanici.fotoUrl
);
print(" ${kullanici.email}");
print("the end");
}
}
}
catch(ex){
print(ex);
}

return Kullanici(id:user.uid,

}
factory Kullanici.dokumandanuret(DocumentSnapshot doc){
return Kullanici(
id: doc.documentID,
userName: doc['kullaniciAdi'],
email: doc['email'],
fotoUrl: doc['fotoUrl']
);
}
}
createUser method:
//Kullaniciolustur
class FirestoreServisi{
final Firestore _firestore= Firestore.instance;
Future<void> kullaniciOlustur({id,email,kullaniciAdi, fotoUrl=""}) async {
await _firestore.collection("kullanicilar").document(id).setData({
"kullaniciAdi":kullaniciAdi,
"email":email,
"fotoUrl":fotoUrl,
"dTarih":""
});
}

When the FacebookIleGiris () method is logged in with Facebook, the function to be initiated to the initiated function and the error has been solved.
facebookIleGiris() async {
print("facebook ile giriş başladi");
FacebookLoginResult _result = await _facebookLogin.logIn(['email']);
switch(_result.status){
case FacebookLoginStatus.loggedIn:
var a= await _loginWithFacebook(_result);
return a;
break;
case FacebookLoginStatus.cancelledByUser:
print("kullanici çıktı");
break;
case FacebookLoginStatus.error:
print("error");
break;
}
}
_loginWithFacebook(FacebookLoginResult _result) async {
FacebookAccessToken accessToken = _result.accessToken;
AuthCredential _credential =
FacebookAuthProvider.getCredential(accessToken: accessToken.token);
AuthResult result = await _firebaseAuth.signInWithCredential(_credential);
print('${result.user.uid} ');
print('${result.user.displayName} şimdi giriş yaptı');
print('${result.user.photoUrl} ');
print('${result.user.email} ');
print(result.runtimeType);
return _kullaniciOlustur(result.user);
