Next.js & Flutter Bug Fixes
Budget: $2 – $8 USD
Our production Next.js web app and its companion Flutter mobile app are both showing a similar set of headaches—functionality glitches, sluggish moments, and a few UI/UX hiccups that break the flow. The two platforms are equally affected, so I need a developer who can jump back and forth between React-based Next.js code and Dart-powered Flutter screens without missing a beat.
Where the problems surface
• Checkout / payment flow stalls or throws unexpected errors
• Poster display and video / audio playback occasionally fail to render or buffer correctly
• File-upload feature hangs or silently drops the upload
What I need from you
• Isolate the root causes on both codebases, commit clean, well-commented fixes, and prove they work.
• Restore full performance—smooth UI, quick API calls, no memory leaks.
• Leave each repo optimised and ready for the next release (build scripts, caching, linting all green).
Acceptance
The Checkout, poster playback, and file-upload journeys must run end-to-end on web and mobile without errors, lag, or layout issues. I will test on the latest Chrome, Safari, and a mid-range Android/iOS device before sign-off.
Tech you’ll touch: Next.js (React 18, SSR with API routes), Flutter 3.x, Dart, REST/GraphQL clients, possibly Firebase and Stripe SDKs.
If debugging, profiling, and polishing across both stacks sounds like your thing, let’s get this shipped.
