'Can't Run flutter app on ios after Amplify update 0.3.2

I get the following error

[!] CocoaPods could not find compatible versions for pod "AmplifyPlugins/AWSCognitoAuthPlugin":
  In snapshot (Podfile.lock):
    AmplifyPlugins/AWSCognitoAuthPlugin (= 1.15.6, ~> 1.15.5)

  In Podfile:
    amplify_auth_cognito (from `.symlinks/plugins/amplify_auth_cognito/ios`) was resolved to 0.0.1, which depends on
      AmplifyPlugins/AWSCognitoAuthPlugin (= 1.19.0)

Specs satisfying the `AmplifyPlugins/AWSCognitoAuthPlugin (= 1.15.6, ~> 1.15.5), AmplifyPlugins/AWSCognitoAuthPlugin (= 1.19.0)` dependency were found, but they required a higher minimum deployment target.

I have set platform :ios, '15.0' in podfile

When I try to open in xcode and build the project I get the following error

diff: /Podfile.lock: No such file or directory

diff: /Manifest.lock: No such file or directory

error: The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.


Solution 1:[1]

from your root flutter project open the terminal and type

cd ios

and then run

pod install

if that doesn't work then run

pod deintegrate

and then

pod install
