Github workflow cache path with fastlane and flutter

I am trying to optimise my cicd deployment workflow for android and ios with cache but I have a problem with the cache path. When not caching the workflow works well but when caching, the fastlane action doesn't find flutter or pods and I get errors like "error: /Users/runner/work/xxx/xxx/ios/Flutter/Release.xcconfig:1: could not find included file 'Pods/Target Support Files/Pods-Runner/Pods-Runner.release.xcconfig' in search paths (in target 'Runner' from project 'Runner')"

  workflow_dispatch:
    inputs:
      lane:
        description: "Staging lane to use : alpha or beta"
        required: true
        default: "alpha"

  deploy-to-ios:
    runs-on: macos-latest

Any idea how to find the path used in fastlane for flutter and pods and cache the files there so they are found ?
