Connective class

A widget that rebuilds based on connectivity state.

Provides different builders for different connection types, or a general builder that receives the connectivity state.

Example with specific builders:

Connective(
  onWifi: Text('Connected via WiFi'),
  onMobile: Text('Connected via Mobile Data'),
  onNone: Text('No connection'),
)

Example with builder:

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