SwiftUI vs Flutter for User Authentication especially Google Auth

 Finally, I have tried both SwiftUI and Flutter for User authentication. 

Here is my take. 

Flutter

I develop the app using flutter for login, 

the guidance I get from this video

The video was nice and simple. From what I remember, 

1. we need to have flutter platform in building it, 

2. prepare both authentication, of web client and ios client

3. And run it. 

The disadvantage

1. Since its not built from native ios app, the emulator was not as fast as the swiftui. 

The second one is using Swift UI and firebase

I follow the guidance from this video 

From what I remember

1. The firebase give very good native feeling to ios.

2. Since its build by Google, the google login very smooth. 

Disadvantage

1. So far I havent found one. 

So now to remember how to do it one more in Firebase auth

1. Make sure you prepare the system ready, create your file for Google Auth in firebase that it will be IOS app.

2. Download your google Plist and put in the ios app file. 

3. Copy the reverse of your google plist to the url scheme of the app. 

4. Add new info in info tab of you app about GClientID and make sure to add the clientID of your Google.

5. And thats all .
