Flutter Bug Fixing Service
Fix Flutter App Errors, Crashes and Release Issues
I diagnose and fix Flutter problems across Android, iOS and web—from build failures and broken APIs to Firebase errors, UI bugs and issues that appear only in release builds.
Is a Flutter Bug Blocking Your App Release?
Share the error message, screenshot or screen recording, Flutter version, target platform and steps to reproduce the problem. I’ll review the details and recommend the most practical next step.
Problems I Fix
Flutter App, Integration and Release Issues
Flutter failures can come from Dart code, state management, native Android or iOS configuration, APIs, Firebase, packages or signing settings. I trace the root cause before applying a focused fix.
Crashes and Runtime Errors
App startup crashes, null errors, platform exceptions, frozen screens, memory issues and device-specific failures.
API and Authentication Issues
Failed requests, incorrect responses, token expiry, Dio errors, CORS problems, OTP flows and Google Sign-In failures.
Firebase and Notifications
Firebase setup errors, SHA certificate problems, push notifications, FCM tokens, Crashlytics and configuration issues.
UI, State and Performance Bugs
Overflow errors, broken navigation, stale state, loading issues, slow screens, duplicate requests and responsive-layout problems.
Release and Play Store Problems
Debug-versus-release differences, signing errors, rejected builds, permissions, app bundles and Play Console release support.
Release-Aware Diagnosis
Find the Cause, Fix It Safely and Test the Real App Flow
You work directly with a senior full-stack and Flutter developer with 14+ years of development experience. I check both the Flutter code and the backend or platform configuration involved in the failure.

Android, iOS, Firebase and signing checks
API requests, responses and authentication diagnosis
State management, navigation and UI investigation
Debug, profile and release-build testing

Frequently Asked Questions
Flutter Bug Fixing FAQs
What Flutter problems can you fix?
I can diagnose build failures, crashes, API and authentication errors, Firebase problems, push notifications, UI overflow, navigation and state issues, package conflicts, release-only failures and Play Store problems.
Can you fix an app that works in debug but fails in release?
Yes. I can investigate signing, Firebase SHA certificates, ProGuard or R8, environment values, permissions, API configuration and other differences between debug and release builds.
Can you fix Google Sign-In and Firebase issues?
Yes. I can review Firebase configuration, Android package details, OAuth clients, SHA-1 and SHA-256 certificates, Google services files and debug, upload or Play App Signing certificates.
What information should I send first?
Send the exact error, screenshot or recording, Flutter version, device and OS, steps to reproduce it, build mode and recent code or configuration changes. Do not send passwords, private keys, tokens or personal data in an unsecured message.
Is the diagnosis fee included in the final repair?
The diagnosis is a separate focused service unless the agreed quotation states otherwise. After identifying the cause, I explain the findings and provide the repair scope, price and delivery estimate.
Can you help publish the corrected app?
Yes. Release support can include signed APK or AAB generation, version updates, internal testing, Play Console checks and guidance for submitting a corrected release.
