Lifecycle

Most of these callbacks are optionals but can be overriden according to our needs.
Developers should use these callbacks instead of system callbacks to maintain a view.

onCreate

void onCreate()

This callback is called only when widget creates the view.

onDispose

void onDispose()

This callback is called only when widget disposes the view.

buildContent

Widget? buildContent(BuildContext context)

This callback is called only when view builds the content.

notifyChanges

void notifyChanges(VoidCallback? callback)

Notify changes in the view and schedule an update. Provided callback is immediately called synchronously.

ViewModel

ViewModel? getViewModel()void setViewModel(ViewModel? viewModel)

Optionally we can assign a view-model for the view. Though optional but should be done inside onCreate.
