FlutterFlow Development Services

Your FlutterFlow app is one Apple rejection away from launch. We get it through review.

Firestore listeners leaking memory until the app crashes. App Store rejections for missing privacy URLs, permission strings, or iPad layouts. Custom actions receiving stale state snapshots. Universal Links not opening on iOS. Document reads spiralling under real load. We fix the Firebase, custom code, and submission issues that stand between you and the App Store.

Common FlutterFlow Problems We Fix

FlutterFlow gets you most of the way to a mobile app. These are the specific blockers we fix before App Store submission.

Firebase Listener Memory Leaks

FlutterFlow auto-generates Firestore listeners that aren’t always cancelled when a widget unmounts. Over a session, these accumulate and eventually crash the app or cause data to appear for the wrong user. We audit all listener lifecycles and fix the cleanup.

App Store Rejection

Apple rejects FlutterFlow apps for missing privacy policy URLs, incorrect permission strings in Info.plist, missing iPad layouts, or submitting a debug build by mistake. We fix the specific rejection reason and navigate the re-submission.

Custom Actions Not Receiving State Updates

Custom Dart actions in FlutterFlow receive a snapshot of state at the time they’re called, not a live reference. State changes that happen inside the action aren’t reflected back to the UI without explicit setState calls. We fix the action-to-widget data flow.

Deep Links Not Working on iOS

Universal Links on iOS require an associated domain entitlement and a correctly formatted apple-app-site-association file on your server. FlutterFlow doesn’t configure this automatically. We implement deep linking end-to-end so share links and email CTAs open directly in the app.

Firestore Query Costs Spiralling

FlutterFlow’s generated Firestore queries often read entire collections when only a subset is needed. Under real user load, document read costs exceed expectations quickly. We add proper query limits, indexes, and caching to bring costs under control.

Exported Code Won’t Build Outside FlutterFlow

FlutterFlow’s code export includes generated files that depend on the FlutterFlow package and don’t compile cleanly in a standard Flutter environment. We migrate the exported project to a standalone, IDE-buildable codebase you can develop independently.

Recognize any of these? We fix them in 2–5 days.
