there is appearing following error
[!] CocoaPods could not find compatible versions for pod "OneSignalXCFramework":
In Podfile:
onesignal_flutter (from `.symlinks/plugins/onesignal_flutter/ios`) was resolved to 3.2.7, which depends on
OneSignalXCFramework (= 3.9.1)
None of your spec sources contain a spec satisfying the dependency: `OneSignalXCFramework (= 3.9.1)`.
You have either:
* out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
* mistyped the name or version.
* not added the source repo that hosts the Podspec to your Podfile.
try running the following command
cd ios/
pod repo update
rm -rf Podfile.lock Pods
pod install
