title: error: 'Flutter/Flutter.h' file not found when flutter run on iOS
body: <p>I don't know why but I can't build or run the App in my new Macbook, I run the same folder on another Mac or my windows computer and runs perfectly.
  here when I run flutter clean, I have to run pub get to solve the issues, Is that normal?</p>
  <p>If I create a new project, I can run flutter run normally, so I think that maybe there
  I think it may be related to plugins.</p>
  <p>Do you know how can I solve this? Thanks</p>
