Suspense<T> class

DSL sugar for SuspenseNode.

Renders fallback while async data is loading, and seamlessly swaps in the resolved content when resource completes.

Future<String> fetchUsername() async {
  await Future.delayed(const Duration(milliseconds: 500));
  return 'Ada Lovelace';
}

BloomNode userProfile() => Suspense<String>(
  resource: fetchUsername,
  fallback: Div(className: 'skeleton-loader', text: 'Loading user...'),
  builder: (name) => Div(className: 'user-card', text: 'Welcome, $name!'),
  errorBuilder: (err, stack) => Div(text: 'Failed to load user: $err'),
);
