Flutter run lost connection to device in iOS

I did an app in android, now trying to run it in ios. I am getting the bellow error

    Xcode build done.                                           35.2s
    Configuring the default Firebase app...

    Syncing files to device iPhone 11...                                    
    (This is taking an unexpectedly long time.)

I have other ios apps which are running perfect.

Running flutter doctor shows this

    flutter doctor

Edit = Removed firebase

I removed the firebase thing and getting a plain message like this

     Running pod install...                                              3.0s

    (This is taking an unexpectedly long time.)       ⣻

Any idea what could be wrong?

Thank you.

You may be creating a Secondary App as described in FlutterFire docs. https://firebase.flutter.dev/docs/core/usage/

The Secondary APP just worked in an Android Environment for me. I found a workaround loading the options from the previously created. In that way, it worked in IOS.

Something like this:

// Uses the default GoogleService-Info.plist
final Future<FirebaseApp> _firebaseDefaultApp = Firebase.initializeApp();

List<FirebaseApp> apps = Firebase.apps;
_firebaseSecondaryApp = Firebase.initializeApp(name: "SecondaryApp", options: apps[0].options);

I know I'm already late here, but this could be caused by improper configuration from Google Map or other API keys from within iOS. Try running the app in Xcode and you will get a more helpful error message.

In my case, it was a Google Map API key missing.

Solution:

Open AppDelegate.swift Add import GoogleMaps along with the other imports Add the following statement above GeneratedPluginRegistrant.register(with: self): GMSServices.provideAPIKey("YOUR_API_KEY_HERE") where YOUR_API_KEY would be something like AIzaSyBHV....wZEIg from the Cloud Console.

You are using Firebase and you probably forgot to add firebase's GoogleService-Info.plist file to your IOS project from xcode.

Also sometimes you need to run pod install inside IOS project to install the required pods.
