IMPORTANT: ensure doing all the below steps using xCode. DON'T use any other IDE or other file explorer. It has to be xCode. xCode does something under the hood when you drag and drop a file to your project which is why you would not use any other IDE to do this.

first: remove all GoogleService-Info.plist from your project.

second: drag and drop a fresh copy of GoogleService-Info.plist to the 'project runner' path

third: try running your project again and it should be working fine.

In Xcode, under the Build Phases of your target, ensure that the GoogleService-Info.plist file is included in the Copy Bundle Resources phase, but is not included in the Compile Sources phase. I had it in both and after removing it from Compile Sources the error was resolved.
