Privacy manifest file for iOS is missing

To ensure a smooth app update and avoid App Store rejection, kindly consider adding a privacy manifest to your library. This helps developers reflect data collection practices in our own manifests.

[Apple documentation.](https://developer.apple.com/support/third-party-SDK-requirements/)

The issue is about adding a privacy manifest file for iOS to comply with App Store requirements. Look at the project's iOS directory structure, likely under `ios/`, and review Apple's linked documentation to understand the required format. Create a `PrivacyInfo.xcprivacy` file with the appropriate data collection declarations for the Flutter package. Verify by checking the package's iOS integration and any existing example app.
