title: How to force Flutter to use new developer certificate?
body: <p>I am currently developing an application with Flutter. I used to be able to run the code directly using VS code or the command <code>flutter run</code>. Ever since I revoked my developer certificate and generated a new one, the above options when executed, the app crashes on my iPhone. If, however, I run it on the simulator, it works as expected.</p>
  
  <p>I suspect that this is due to the change in certificates. Xcode says my app is signed with the certificate B39****** where as <code>flutter run</code> says it is signing with 578*******</p>
  
  <p>I have even tried <code>flutter config --clear-ios-signing-cert</code> as well as <code>flutter upgrade</code> and it still signs with 578.</p>
  
  <p>How can I force flutter to sign my app with the new certificate? Currently, this means I cannot use the hot reload feature on my physical devices.</p>
