Hey guys,

Here at ArcTouch, we are exploring the Flutter modules and all its power. We were able to integrate a module on both Android and iOS and it works great on debug. However, when we release a build on our Jenkins, we get an error when the app is opened.

We know the "add-to-app" support is still in preview, but we created a release build for Android and it worked, but it doesn't work for iOS, with the following error:

Termination Description: DYLD, Library not loaded: ./libFlutter.dylib | Referenced from: /var/containers/Bundle/Application/FC2EB865-A3C1-45F6-86AE-186D59120D73/example_ios.app/example_ios | Reason: image not found

Steps to Reproduce

  1. Create a flutter module (we used example_module for the project name)
  2. Create a new iOS project on xcode (we used example_ios)
    1. We are using xcode 11, so we deleted SceneDelegate.swift.
  3. Run pod init in example_ios
  4. Add the following to the generated Podfile:
flutter_application_path = '../example_module/'
load File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')

target 'example_ios' do
  use_frameworks!

  # Pods for example_ios
  install_all_flutter_pods(flutter_application_path)
end
  1. Run pod install
  2. Follow the add-to-app tutorial and make the changes to import the module
  3. Sign your iOS native project
  4. Try to create a release build of the iOS app

Target Platform: iOS
Target OS version/browser: 11.0+
Devices: Any

DEMO

Debug

Release

Note

We don't know if it's necessary to build the module before building the iOS app. We are just not sure how to change the build variant for the Flutter module and even if we have to change at all. We tried to build only the module (without integrating) to create an iOS app in release and it worked. That's why we are building the module before building the app. We tried first without building the module, but we were getting the same error.
