onInit property

Function to execute when the widget is first created.

This is called once during initState and is useful for initializing the notifier or performing one-time setup operations.

Example:

NotifierBuilder<DataNotifier, List<String>>(
  onInit: (notifier) {
    notifier.loadData(); // Load data when widget is created
  },
  builder: (context, data, child) => ListView.builder(
    itemCount: data.length,
    itemBuilder: (context, index) => ListTile(title: Text(data[index])),
  ),
)
