Flutter Restaurant POS App Launch

I have a fully-coded Flutter POS application built for a restaurant environment and now I’m ready for the very last mile: getting it live on the App Store and Google Play. The app already handles table management, real-time order tracking and flexible menu customization, and it ties into an existing inventory management system. All screens, assets and icons are in place; what I need is someone who can:

• Review the current Flutter project, make sure it meets Apple and Google publication guidelines and resolve any SDK or policy warnings.
• Generate production-ready iOS and Android builds, including proper signing, certificates and provisioning profiles.
• Walk me through (or directly handle) the submission process so the listings pass review first time, covering screenshots, descriptions and privacy details.
• Provide a short hand-off note or video explaining how to push future updates using the same pipeline.

If you have recent experience launching Flutter apps that rely on device permissions, networking and external integrations, your guidance will be invaluable. I can share the Git repo and current test builds as soon as we agree on the timeline.
