Conversation
Wrapped the BatchItem component in `React.memo` to prevent unnecessary re-renders of the entire list when a single row's state changes. Memoized the `showQrModal` function using `useCallback` in the List component to pass a stable reference to `BatchItem`, ensuring `React.memo` functions correctly. This significantly improves rendering performance when interacting with items in large lists. Co-authored-by: AntonioCardenas <11583391+AntonioCardenas@users.noreply.github.com>

💡 What:
Wrapped the
BatchItemcomponent inReact.memoand memoized theshowQrModalcallback inList.tsxusinguseCallback.🎯 Why:
Previously, any state change in the parent
Listcomponent (such as opening the QR code modal which updatesqrCodeUrlstate) would cause every singleBatchItemin the list to re-render. Since lists can contain many items, this caused noticeable rendering overhead. By memoizing the component and its callback prop, we prevent these unnecessary renders.📊 Impact:
Reduces re-renders of
BatchItemcomponents by O(N) (where N is the number of visible batches) when performing actions that update parent state, such as opening a QR modal or interacting with search inputs.🔬 Measurement:
Use the React Profiler to record rendering while clicking a QR code in the coffee batch list. Before the change, all rows re-render. After the change, only the parent component re-renders, while the
BatchItemcomponents skip rendering.PR created automatically by Jules for task 16167285758856540106 started by @AntonioCardenas
