title: fatal error: module 'firebase_core' not found
body: <p>Just created a new flutter project, added google-services-info.plist file to iOS and added firebase_core to pubspec.yaml. Ran the project and got this error. 
  <code>Error: fatal error: module 'firebase_core' not found  @import firebase_core;</code></p>
  
  <p>I have searched a lot on the stack overflow and gitlab. Tried all the workarounds like flutter clean, update repo, delete pod and reinstall pod but still got no success in resolving this error.</p>
  
  <p>This has blocked me for 5 days. Unable to find anything on this.
  Please help.</p>
  
  <p>Link to my project on GitHub. : <a href="https://github.com/infonotics/stocklyticsSO" rel="noreferrer">https://github.com/infonotics/stocklyticsSO</a>
  Do add your own googleService-Info.plist file to the Runner folder. I have removed my file for security reasons. </p>
  
  <p>Thanks in advance.</p>
