Flutter Developer Needed for Discovery Feed and Performance Issues

@rahuliitm69

Hi there, As you are working with Flutter + Firebase, this kind of issue usually comes from Firestore query limits, pagination logic, hidden filters, or inconsistent document indexing where some users silently get excluded during fetch. Once you share the current feed query logic and Firestore structure, I will start by tracing how profiles are being fetched, filtered, and paginated to identify why only partial or repeated results are coming. Then I will fix the root cause in the query layer and data handling so the discovery feed consistently pulls all valid profiles without repetition or missing users across both new and old accounts. I have spent the decade working on Flutter and Firebase-based apps also with the dating apps which you can check from my profile. I would request to connect once so I can quickly review the current implementation and suggest the most stable fix. Thanks, Rahul A.

Hi there, I have read your project requirement. You need an experienced Flutter + Firebase developer to debug and fix discovery feed issues in your dating/live streaming app, including inconsistent profile loading, repeated profiles, Firestore query problems, and feed logic instability across user accounts. Our team has experience building and debugging Flutter social/dating applications using Firebase Auth, Cloud Firestore, real-time feeds, matching systems, and scalable recommendation/query architectures. Based on your description, possible causes could include: ============================================== Firestore query limits/indexing issues Pagination or cursor problems Cached/stale query states Filtering logic inconsistencies between old/new accounts Improper exclusion lists or seen-profile tracking Firestore composite index or query ordering conflicts A few questions: ============= Are you using Firestore pagination with startAfter/startAt cursors? Is profile visibility controlled by Cloud Functions or directly in-app? Do you maintain “seen/swiped” profile collections separately? Are there any Firestore security rules that may affect feed visibility? Best Regards, Srashtasoft Team

Hi, the feed issues you’re experiencing are likely caused by Firestore query limitations, inconsistent pagination, or filtering logic that inadvertently excludes certain users. Differences between old and new accounts suggest that some user documents may not match the current feed query structure, or that index/permission issues are affecting results. I would start by adding detailed logging on each query, analyzing how filters and pagination behave for all account types, and auditing your Firestore rules and indexes. Then I’ll rewrite the fetching logic to ensure consistent results, proper ordering, and robust handling of all profiles. I can also implement debugging hooks so you can monitor exclusions in real time. I have previously debugged Flutter apps with live discovery feeds, social matchmaking, and real-time Firestore syncing, resolving missing profile issues, repeated items, and query inconsistencies. Best regards, Waqas A

Hi! The fact that your discovery feed shows just three profiles or misses users, even after widening the filters, points to either a query limit or hidden data rules in Firestore. The bit about newer versus older accounts behaving differently really hints at edge cases in privacy flags or document reads. I've dealt with feed and filter bugs before — CawGo is a live app we built with similar feed logic and tight Firebase Auth rules (React Native, but same Firestore headaches). First, I'd add on-device logging for query responses and rejected IDs. That way we spot silent skips. Then check Firestore security rules, index limits, pagination overlaps, and whether you hit the 10MB doc limit or cursor bugs. Usually, one small off-by-one mistake in query paging or a broken stream subscription causes half the trouble. One quick question, has anyone checked for old accounts with disabled/archived flags or missing key fields? That breaks feed joins more often than you'd think. If you want, I can send you a 1-page debug plan with the exact Firestore checks and quick log hooks. For examples, I keep similar mobile/debug jobs up at work.techindika.com. — Pradeep

@chandibraheem58

Hi, This issue is likely caused by Firestore query limits, pagination logic, cached filters, or inconsistent user-document structures between old and new accounts. That’s why some profiles repeat, disappear, or stop loading after a few results. With 6+ years of experience in Flutter, Firebase, and social feed systems, I can debug the discovery flow properly, trace profile exclusion logic, fix query/filter issues, and add logging tools to identify why profiles are being skipped. My approach: 1. Audit Firestore queries and pagination 2. Check filters/exclusion logic 3. Add debug logging for rejected profiles 4. Test across multiple devices/accounts Have you implemented `startAfterDocument` pagination or any local feed caching currently? Best Regard, Chand

I am an experienced Flutter & Firebase developer and have worked on similar discovery/feed-based apps. Your issue likely comes from Firestore query limitations, incorrect filtering logic, or inconsistent pagination causing partial or repeated results. Sometimes Firebase where clauses combined with pagination (limit/startAfter) or client-side filtering excludes valid users unintentionally. I will debug your Firestore queries, review feed generation logic, and add logging to identify exactly why profiles are being skipped or repeated. I will ensure a stable and consistent discovery feed across all devices by optimizing query structure and eliminating duplication issues. I can start immediately and fix this issue with a clean, scalable solution for long-term performance.

i, I can help debug and fix the discovery feed issues in your Flutter/Firebase dating app and identify the actual root cause instead of applying temporary patches. I have strong experience with Flutter, Firebase Auth, Cloud Firestore, real-time feeds, filtering logic, and large-scale user matching systems. I’ve worked on apps involving recommendation feeds, pagination, profile filtering, and Firestore query optimization where inconsistent results, repeated profiles, and missing records needed deep debugging. Based on your description, the issue may be related to Firestore query limits, improper pagination state, cached query snapshots, inconsistent filters between old/new accounts, exhausted query cursors, or exclusion logic silently removing valid users. I would start by tracing the full profile-fetching flow, reviewing Firestore indexes and query conditions, and adding structured logging to identify exactly why profiles are being skipped or repeated. I can also improve the feed architecture to ensure stable pagination, balanced profile rotation, consistent filtering behavior, and reliable loading across devices and account types. Alongside the fix, I can implement debugging tools and logs that make future feed issues much easier to trace and maintain. The goal will be to restore consistent profile discovery behavior while keeping the system scalable as your user base grows. Best regards, Ihor

The core challenge lies in the significant performance issues tied to profile discovery, where repeated profiles and empty states plague user experience. Addressing Android ANR requires a nuanced understanding of Flutter's architecture and effective optimization strategies. By leveraging advanced techniques such as asynchronous data fetching and optimized pagination algorithms, we can enhance loading times and ensure relevant user profiles display correctly. Moreover, debugging Play Console crashes is vital for app stability. I propose a roadmap with the initial deliverable ready in 14 days. Want to see a quick deliverable preview before committing?
