I have a production-ready Flutter application that currently runs only on Android and needs a quick but thorough health check. The latest build shows a mix of crash bugs, UI glitches, and general sluggishness that appeared after I integrated a few new screens. While I don’t have full crash logs to hand, I can walk you through the exact user flows where problems surface and provide screenshots or screen recordings so you can reproduce the issues on your side. Your task is to locate the root causes, patch them cleanly, and supply an updated build along with concise notes on each fix. Expect to work with recent Flutter and Dart versions, Android Studio, and common debugging tools such as Flutter DevTools, logcat, and profiler widgets. Deliverables • Stable, crash-free code committed to Git (or a ZIP if you prefer) • Polished UI that matches the current Figma design and renders consistently on phones and small tablets • Noticeable performance improvement in the affected screens (scroll jank eliminated, frame rate back to 60 fps) • Release-ready APK/AAB plus a short change-log summarising the fixes and any refactors I’m ready to test each interim build and can provide immediate feedback. Let me know your estimated turnaround time and the way you like to structure milestones so we can get this update shipped swiftly.

Hi, I can quickly stabilize your Flutter app and eliminate the crashes, UI glitches, and performance issues introduced after the new screens. I will reproduce each problem using your recordings, trace root causes with Flutter DevTools, logcat, and profiler tools, then apply clean, maintainable fixes. I’ll also optimize rendering, remove jank, and ensure smooth 60 fps performance across devices. A few quick questions: • Which Flutter/Dart versions are you currently using? • Are state management tools like Provider, Bloc, or Riverpod involved? • Any third-party plugins recently added? • Do crashes occur on specific devices or Android versions?

Hi there, I’m Justin. I’ve worked on Flutter apps that were “almost there” but started breaking after new features were added—so I know exactly how this situation feels. I can jump in, reproduce the crashes from your flows, trace the root causes (logcat, DevTools, profiler), and fix them cleanly without creating new issues. I’ll also smooth out the UI glitches and get performance back to a solid, consistent 60fps. You’ll get a stable build, clean fixes committed to Git, and short notes so you know exactly what changed and why. I keep things practical and focused—no overengineering, just a solid, reliable app ready for release. I can start right away and move quickly with your feedback on each build. —Justin

❤️❤️❤️ Flutter app debugging, performance tuning & UI stabilization ❤️❤️❤️ I’m interested in this project because I have experience diagnosing and fixing Flutter applications with crash issues, UI inconsistencies, and performance bottlenecks introduced after feature additions. I understand how to quickly reproduce issues, trace root causes, and apply clean, maintainable fixes. The core challenge is identifying the root causes behind crashes, UI glitches, and sluggish performance in recently added screens, then optimizing rendering, state management, and widget rebuilds to restore stability and smooth 60 fps performance across devices. My approach is to reproduce the reported user flows, analyze logs using Flutter DevTools, logcat, and profiler tools, inspect widget trees and state updates, and identify inefficient rebuilds or misconfigurations. I will fix crashes, optimize layouts, eliminate jank, and ensure consistency with the Figma design, followed by testing across devices and delivering a stable release build with clear documentation of all changes. I will provide clean, production-ready code, improved performance, and concise change logs, while maintaining clear communication and working efficiently with your feedback loops to deliver a fast turnaround.

Hello, As I am a senior mobile engineer, I can do these Flutter Android app bug fixes in 3 days for $120. Your main issue is usually not the visible bug itself, but the unstable part underneath it such as widget state, async API flow, plugin/version mismatch, Gradle or Android-specific behavior, or broken edge-case handling. I would first reproduce each issue on a clean build, trace logs in Android Studio, isolate whether it is UI, state management, API, or native Android layer, and then patch it without creating new regressions. I have strong Android and Flutter experience, including building and fixing production mobile apps, improving UI/UX, resolving bugs, and working through full app lifecycle issues from implementation to release. I can also do one stabilization pass after fixes so the app is cleaner and more reliable instead of just quick patching. Thank you.

Hello, Post-integration crashes and UI regressions in Flutter almost always trace back to widget rebuild cycles, state management conflicts, or unhandled async gaps introduced alongside the new screens — finding the root cause is more important than patching symptoms. Here's my approach: - Full reproduction of reported flows using your screen recordings and walkthroughs - Root cause diagnosis via Flutter DevTools, logcat, and profiler widgets — not surface-level fixes - Crash patches committed cleanly with clear notes on what caused each issue - UI polish pass to match your Figma design consistently across phones and small tablets - Performance audit on affected screens — scroll jank eliminated, frame rate restored to 60fps - Release-ready APK/AAB + concise changelog summarising every fix and refactor Code will be clean and maintainable — structured so the new screens integrate without fragility. I'll personally verify each fix against your test feedback before the final build is delivered. Getting this right matters more than rushing it — happy to align on scope and budget once we've connected. One question: are the new screens using a state management solution (Provider, Riverpod, Bloc), or is state being handled locally at the widget level?

FIXING CRASHES FAST AND MAKING YOUR APP SMOOTH AGAIN Hi, I can help you quickly identify and fix the crash issues, UI glitches, and performance problems in your Flutter app. I’ve worked on similar apps where new screens caused instability, and I focus on clean fixes — not temporary patches. I’ll debug using Flutter DevTools, logcat, and profiling to find root causes, optimize rendering, and bring performance back to smooth 60fps. I’ll also ensure UI matches your Figma design properly. You’ll get clean code, updated build (APK/AAB), and a clear changelog. Quick question: Which Flutter version are you currently using? I can start immediately and deliver fast. Thanks, Sahil

Hi, I’ve reviewed your request for a comprehensive health check and stabilization of your Flutter application. Performance degradation and crashes after adding new screens usually point to state management leaks or expensive build methods. As a senior developer with 20 years of experience and founder of RK Origin studio, I specialize in deep-level optimization and "surgical" bug fixing. How I will restore your app’s performance: Performance Audit (60 FPS Goal): I will use Flutter DevTools and the CPU Profiler to identify widget rebuild bottlenecks. My goal is to eliminate scroll jank and ensure smooth rendering even on mid-range devices. Crash Root Cause Analysis: Even without full logs, I will use Logcat and Sentry/Crashlytics to trace null-pointer exceptions or asynchronous race conditions that are causing your recent builds to fail. UI Polishing: I'll ensure the implementation strictly matches your Figma design, fixing any overflow errors or inconsistent layouts across different screen sizes and tablets. Clean & Stable Delivery: You will receive a stable, crash-free codebase with concise notes on every fix. I work fluently with Git and follow a "zero-regression" approach. Best regards, Ruslan Founder, RK Origin Studio
