error: Build input file cannot be found: '/Users/GoogleService-Info.plist' (in target 'Runner' from project 'Runner')

Question

I'm trying to take the iOS build of a Flutter project. No matter what I try it just gives me the following error:

error: Build input file cannot be found: '/Users/GoogleService-Info.plist' (in target 'Runner' from project 'Runner')

This is the set of commands I am trying to get the build with:

• flutter pub get
• flutter clean
• flutter build ios (this gives the above error)

Here is my flutter doctor output

The flutter build ios --verbose ends with following error:

Encountered error while building for the device.

Here is the image of the folder structure. As you can see, there is no 'Users' folder that holds the Google plist. So, it is quite confusing why would the script try to copy the plist from a non-existing directory. Any advice to fix this would be highly appreciated. TIA :-)

Answer 1

Remove the GoogleService-Info.plist and then again add the file into the Runner directory using Xcode, then choose copy items if needed and add to target checkmark. I hope this will solve your problem.

Answer 2

Eventually I found the way to fix it:

1. Download the new GoogleService-Info.plist file from Firebase

2. Place it in the ios/Runner directory of your flutter project (put GoogleService-Info.plist into Runner directory NOT in XCode)

3. open XCode with open ios/Runner.xcworkspace

4. In XCode, drag the file GoogleService-Info.plist from your finder, to the yellow Runner folder underneath the blue RunnerProject`, (in the project navigator on the left side of the screen)

5. Next, flutter run
