SConnectivityOverlay class

A convenience wrapper that sets up the Modal overlay system so that AppInternetConnectivity's "No Internet" snackbar (and any other Modal features) work without the user having to know about Modal.appBuilder.

Safe to use even if you already wrap with Modal.appBuilder. Modal.appBuilder is idempotent — calling it more than once simply returns the child as-is, so no double-nesting can occur.

Usage

Option 1 – static builder (simplest, replaces Modal.appBuilder):

MaterialApp(
  builder: SConnectivityOverlay.appBuilder,
  home: MyHomePage(),
)

Option 2 – widget wrapper (if you need to chain multiple builders or customise Modal parameters):

MaterialApp(
  builder: (context, child) {
    return SConnectivityOverlay(
      child: child!,
    );
  },
  home: MyHomePage(),
)

Option 3 – used alongside an existing Modal.appBuilder (safe):

MaterialApp(
  builder: (context, child) {
    // Either order is fine — Modal.appBuilder is idempotent.
    child = Modal.appBuilder(context, child);
    return SConnectivityOverlay(child: child!);
  },
  home: MyHomePage(),
)

In all cases the full Modal system (snackbars, dialogs, sheets) is available throughout the app.
