NetworkAwareNavigatorObserver class

A custom NavigatorObserver that displays a widget or overlay when the device's network connection changes.

This observer listens to changes in the network state using NetworkMonitor and displays a custom widget or overlay when the connection is lost. It supports two modes of operation, controlled by the errorType property: displaying an overlay or displaying a widget.
