Get a Flutter or Firebase bug fixed, at a fixed price

A build that won’t compile, a login loop, a Firestore write that never finishes. Send the repo and the steps to reproduce it; you get the root cause with evidence, then a fix delivered as a pull request with a test that keeps it fixed.

Pay $450 for a DiagnosisPay $1,200 for a Fix

Diagnosis $450 in 3 business days, credited toward the fix. Fix $1,200 in 5 business days. Counted from repo access and reproduction steps.

No call needed. Questions go to contact@app369.com; we reply by email, usually within one business day.

This fits when

  • One bug has already cost you more than a day
  • iOS or Android builds fail after a Flutter or FlutterFire upgrade
  • Users land back on the sign-in screen, or the app flickers between screens
  • Firestore writes hang, or a Cloud Function only returns “internal”
  • A screen goes red in debug or grey in release

How it works

  1. Step 1

    Pay and send the repo

    Pay for the Diagnosis or, if you already know the cause, the Fix. Reply to the Stripe receipt with repo access and the exact steps to reproduce the bug.

  2. Step 2

    Reproduce and isolate

    The bug is reproduced on the build and device class you name, then isolated to the app, Firebase or the build tooling, using the Firebase Emulator Suite where it applies. Your production data is never touched.

  3. Step 3

    Root cause and a fixed quote

    The Diagnosis ends with the root cause, the evidence for it and a fixed repair quote. If you go ahead, the $450 is credited.

  4. Step 4

    Fix as a pull request

    The Fix arrives as a pull request with a regression test and handover notes. You review and merge it.

Questions before you pay

What if I already know what’s wrong?
Buy the $1,200 Fix directly and include what you know. If it turns out to be more than one scoped defect, you get a written quote before anything extra is done.
Do you work on FlutterFlow or other generated code?
Yes, if the project exports to a Flutter repository you can share. The fix is delivered as a pull request against that repository.
Can you guarantee App Store or Play approval?
No. Review decisions belong to Apple and Google. The Fix Ticket covers the code defect itself.
Do I need a call before I pay?
No. The scope, price and delivery time are on this page, and everything happens in writing. If you want to talk live, calls cost $100 per 15 minutes, paid upfront.
Who owns what you deliver?
You do. The code, videos and files delivered under this offer belong to you once paid.
