Flutter plugin fails to build on iOS

0 votes

I've installed flutter_nearby_messages_api and there is an error when building the iOS app:

 Failed to build iOS app
[        ] Error (Xcode): Multiple commands produce '/build/ios/Debug-iphonesimulator/Runner.app/Assets.car'
           
[   +1 ms] Could not build the application for the simulator.
[        ] Error launching application on iPhone 14 Pro Max.

I've even tried to rebuild the flutter plugin myself and got the same error after adding s.dependency 'NearbyMessages' to the <plugin>.podspec file. I'm not an iOS developer, but i think it has to do with CocoaPods somehow.

This is in the Podfile.lock of the flutter plugin:

PODS:
  - Flutter (1.0.0)
  - flutter_nearby_messages_api (0.0.5):
    - Flutter
    - NearbyMessages
  - GoogleInterchangeUtilities (1.2.2):
    - GoogleSymbolUtilities (~> 1.1)
  - GoogleNetworkingUtilities (1.2.2):
    - GoogleSymbolUtilities (~> 1.1)
  - GoogleSymbolUtilities (1.1.2)
  - GoogleUtilitiesLegacy (1.3.2):
    - GoogleSymbolUtilities (~> 1.1)
  - NearbyMessages (1.1.1):
    - GoogleInterchangeUtilities (~> 1.2)
    - GoogleNetworkingUtilities (~> 1.2)
    - GoogleSymbolUtilities (~> 1.1)
    - GoogleUtilitiesLegacy (~> 1.3)

I hope someone can help me, i would have added a issue but the flutter plugin is not on a public repository.

It looks like the error is related to CocoaPods, which manages dependencies for iOS projects. The error message suggests that there are multiple commands trying to produce the same file, which can happen when there are conflicting dependencies.

To fix the issue, you can try the following steps:

  1. Make sure you have the latest version of CocoaPods installed by running pod --version in your terminal. If you don't have it installed or if it's an older version, you can install it by running sudo gem install cocoapods.

  2. Delete the Podfile.lock file and the Pods directory in your project directory.

  3. Run flutter clean in your terminal to clear any cached build artifacts.

  4. Open the iOS project by running open ios/Runner.xcworkspace in your terminal.

  5. In Xcode, select the Runner target and go to Build Phases > Copy Bundle Resources. Make sure that there are no duplicate entries for the Assets.car file.

  6. If you still encounter the error, try removing the NearbyMessages dependency from the plugin's podspec file and see if the project builds successfully without it. If it does, then the issue may be related to that dependency.

  7. If removing the dependency doesn't fix the issue, you can try manually adding the dependency to your project's Podfile by adding pod 'NearbyMessages' and running pod install in your terminal.

If none of these steps work, you may need to reach out to the plugin's developers for further assistance or consider using a different plugin for your project.
