Connective class

A widget that rebuilds based on connectivity state.

Use noInternet to show a fallback widget when the device has no internet connection (wifi, mobile, or ethernet).

Example:

Connective(
  noInternet: Center(child: Text('No internet connection')),
  child: MyContent(),
)

Example with builder for full control:

Connective.builder(
  builder: (context, state, results) {
    if (state == NyConnectivityState.none) {
      return OfflineBanner();
    }
    return child;
  },
)
