Hello, Your real risk is not simply finding Flutter issues, it is missing the security, performance, and API weaknesses that can surface after release. I can audit the shared Dart/Flutter codebase, Android-specific behavior, backend integration, authentication, dependency exposure, state management, widget rebuilds, memory usage, startup performance, and offline resilience. I’ll document each finding by severity with exact file, function, or widget references, actionable remediation steps, and quantified performance observations where measurable. My Software Development and Software Testing experience supports a structured review, while API Integration and Mobile App Development knowledge helps connect client-side findings to backend risks. I’ll collaborate around read-only access, APK profiling, test credentials, and your architecture notes, then provide a focused Markdown or PDF report within the agreed review window. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Please share repository access, the latest APK, API documentation, and any known production concerns so we can finalize the audit plan. Can you provide the repository, APK, API documentation, and test credentials, and should performance profiling cover physical Android devices or emulators? Thanks, Asad Looking forward to your reply so we can finalize the exact plan.

Hi, For a live Flutter app, I’d focus the audit on finding issues that can actually affect production—not simply generating a checklist of Flutter best practices. I’d review the architecture/state management, dependency tree, authentication and sensitive-data handling, network/API layer, and the Android runtime/build characteristics. Findings would be tied to specific files, functions or widgets and classified by severity, with practical remediation steps. For performance, I’d distinguish measurable issues such as rebuilds, startup/build size or memory behavior from areas that only need architectural improvement. I’d also trace the Flutter → API → backend flow for authorization, error handling, synchronization and failure scenarios. The final Markdown/PDF report would prioritize what should be fixed before further development versus what can be addressed later. The ₹4,000 budget and 2–3 hour assessment window can be discussed based on the repository size and backend scope so the audit coverage is realistic. Please open your chat, I am waiting your positive response.

You need a full Flutter audit of the Kirtan app covering code quality, security, performance and the backend, with findings you can act on rather than vague observations. I'd start with the repo structure, state management and dependency versions, then trace security: insecure storage, leaked keys, weak auth and outdated packages. Performance gets measured, not guessed — frame drops, rebuilds, memory and APK size — with numbers attached so you can see what changed. Backend review covers endpoint security, sync, offline handling and error resilience. You'll get a Markdown or PDF report with severity levels and step-by-step remediation, code annotations pointing at specific files and widgets, plus follow-up answers, and I'll delete everything shared within 48 hours per the NDA. Which area worries you most right now: performance, security, or the backend integration?

Hi, I see the Kirtan App's Flutter codebase needs a thorough audit, and I'd approach this by checking the state management choices and widget tree optimization first. This is crucial because poor state management can lead to performance issues and make the code harder to maintain. I'll set up a review process that covers platform-specific nuances, the shared Flutter codebase, and the supporting backend. I've found that a common mistake in Flutter projects is not properly handling technical debt, which can lead to security vulnerabilities and performance issues over time. My approach is to identify these issues and provide clear, actionable remediation steps, so the client can expect a detailed report with quantified performance metrics and a production-readiness assessment as a result. I'll check for insecure storage, improper network calls, and weak authentication logic, and provide step-by-step guidance on how to fix these issues.
