Business Need
The existing Flutter application relied on a deprecated barcode scanning library that was no longer supported and incompatible with newer Flutter SDK versions. Build issues, outdated tooling, and tightly coupled scanning logic introduced risk to a live production app. A full rewrite was not feasible — the solution needed to be precise, safe, and incremental.
