Welcome to the Group Chat Flutter with firebase + Clean Architecture course. We are going to build Group Chat App with Firebase + Clean architecture proposed by Robert C. Martin (Uncle Bob). You'll learn how to write clean, structured and most importantly bug-free code. Having a proper architecture is extremely critical as soon as your project grows to a substantial size. Whenever you are building an app with a UI, you should design the UI and UX first.
@override
Future<void> googleAuth() async{
final GoogleSignInAccount? account = await googleSignIn.signIn();
final GoogleSignInAuthentication googleAuth = await account!.authentication;
final authCredential= GoogleAuthProvider.credential(idToken: googleAuth.idToken,accessToken: googleAuth.accessToken);
final userInformation=(await auth.signInWithCredential(authCredential)).user;
getCreateCurrentUser(
UserEntity(
name: userInformation!.displayName,
email: userInformation.email,
gender: "",
dob: "",
phoneNumber: userInformation.phoneNumber,
profileUrl: userInformation.photoURL,
status: "",
isOnline: false,
),
);
}
@override
Future<void> getCreateCurrentUser(UserEntity user) async{
final userCollection = fireStore.collection("users");
final uid= await getCurrentUserId();
userCollection.doc(uid).get().then((userDoc) {
final newUser=UserModel(
gender:user.gender,
isOnline: user.isOnline,
name: user.name,
phoneNumber: user.phoneNumber,
profileUrl: user.profileUrl,
status: user.status,
email: user.email,
dob: user.dob,
uid: uid,
).toDocument();
if (!userDoc.exists){
userCollection.doc(uid).set(newUser);
}
return;
});
}
