title: Step to configure ML Kit library model in podfile - flutter apps
body: <p>I am new in using ios, and right now I am using this package <a href="https://pub.dev/packages/firebase_ml_vision" rel="nofollow noreferrer">https://pub.dev/packages/firebase_ml_vision</a> to do face detection... here is said that
  <code>If you're using one of the on-device APIs, include the corresponding ML Kit library model in your Podfile. Then run pod update in a terminal within the same directory as your Podfile.</code> and right now I am using 'Firebase/MLVisionFaceModel' and I need to do <code>pod 'Firebase/MLVisionFaceModel'</code>... since I am new in using ios, I am trying to find a tutorial how to configure it in ios, but I still don't find yet... what I don't understand here is how to include the corresponding ML Kit library model in my Podfile... should I edit it inside Xcode or inside ios folder in my flutter project?... is anyone here know how step by step to configure it?
  and here is what I get when I didn't set that up</p>
