Steps to Reproduce

Example project located here:
https://github.com/thunderheadone/one-sdk-flutter/tree/feature/MOB-1367_Add-Flutter-to-existing-app-example/examples/ios-add-flutter-to-existing-app-example

  1. In terminal, navigate to to examples/flutter_module_example/
  2. Run flutter clean, then flutter pub get
  3. Navigate to ios-add-fluter-to-existing-app-example
  4. Run pod install

Expected results:
pod install works okay and ios project with Flutter module added works.

Actual results:
After upgrading Flutter from v1.22.1 to v2.2.1 stable, trying to run pod install from the iOS project ios-add-flutter-to-existing-app-example with flutter_module_example module (add to app) produces the following error:

Analyzing dependencies
[!] No podspec found for `Flutter` in `../flutter_module_example/.ios/Flutter/engine`

It seems like the Flutter.podspec is missing in the generated .ios/Flutter/engine directory. When I switch to 1.22.1 and run flutter pub get from the flutter_module_example directory, the podspec is generated. Same command on 2.2.1 does not generate the podspec.

Hi @th-anguyen
Thanks for filing the issue

I can reproduce the issue using code

tahatesser@Tahas-MBP ios-add-flutter-to-existing-app-example % pod install

[!] No podspec found for `Flutter` in `../flutter_module_example/.ios/Flutter/engine`

tahatesser@Tahas-MBP ios-add-flutter-to-existing-app-example %

However, I see that you've non-hidden iOS folder. Flutter module generated .ios folder which is hidden by default and you're not supposed to modify it as this is generated

I simply deleted you non-hidden ios and executeflutter pub get and it generates new .ios folder and then executed pod install in the ios-add-flutter-to-existing-app-example

As you can see all the pods are installed and we don't get No podspec error

Also ran into this issue. Same procedure used like @TahaTesser to solve it.

@TahaTesser The solution you proposed works in op's use case, however it is not acceptable for me. The reason being is that my Flutter project is both a module and a stand-alone app. Consequently, I need both the ios and .ios folders. I therefore think there will need to be a more sophisticated fix for this issue.

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
