💡 What: Cached the list of `NavigationDestination` widgets in `MainScreen` to prevent them from being recreated on every build. 🎯 Why: The `build` method was unnecessarily calling `_buildNavDestinations()` on every invocation, creating a new list of widgets each time. This caused redundant widget creation and reconciliation work for the framework, even when the underlying data (the offline status) hadn't changed. 📊 Impact: Reduces widget rebuilds within the `MainScreen`'s `NavigationBar`, leading to a more efficient render cycle. This is a micro-optimization that contributes to overall smoother UI performance by avoiding unnecessary work on each frame. 🔬 Measurement: This can be verified by observing the widget rebuilds using Flutter DevTools. Before the change, the `NavigationBar` and its `NavigationDestination` children would rebuild on every state change in `MainScreen`. After the change, they only rebuild when the offline status actually changes.

This optimization caches the
NavigationDestinationwidgets in theMainScreento prevent unnecessary rebuilds. By creating the list only when the offline state changes, we reduce widget churn and improve rendering efficiency. This is a small but effective change that contributes to a smoother UI.PR created automatically by Jules for task 9330571732905481225 started by @Doezer
