Flutter not building iOS application, is it a swift error?

Question

I'm not longer able to build an iOS app with XCode, even a brand new flutter application will not run.

Here's the version of Android Studio:

Android Studio 3.1.4 Build #AI-173.4907809, built on July 23, 2018 JRE: 1.8.0_152-release-1024-b01 x86_64 JVM: OpenJDK 64-Bit Server VM by JetBrains sro Mac OS X 10.13.6

Here's the version of XCode:

Version 9.4.1 (9F2000)

I get the following error:

Answer 1

The error is saying:

"An App ID with Identifier 'com.test.flutterApp' is not available. Please enter a different string"

You need a different bundle id for your project as com.test.flutterApp may be registered under different Apple ID. Change it to anything unique and try to run it

EDIT

The new error says: GoogleService-Info.plist couldn't be found at

/Users/pbirdsall/Documents/highline/LeverageGoogleServersPlist/GoogleService-Info.plist

Make sure you have the plist file.
