maybeOf<T> method

T? maybeOf<T>(BuildContext context)

Reactively discovers and observes an optional ancestor BloomProvider<T> within context.

Connects BloomBuildContextProviderExtension.maybeBloomOf with this BloomVia tracking scope in a single, fluent call, eliminating nested via(context.maybeBloomOf<T>()) boilerplate.

• context: The active BuildContext to locate the ancestor provider from.

Exact Type Resolution:

• Lookup matches the exact reified type T. Subtypes or base classes do not match.

Ensures:

• Subscribes this reactive tracking scope to the ancestor Bloom<T?> node if found, or Bloom.constantNull if no matching provider exists.
• Returns the underlying value of type T?.

Examples

@override
Widget build(BuildContext context, BloomVia via) {
  final theme = via.maybeOf<AppTheme>(context);
  return Text(theme?.name ?? 'Default');
}

Implementation

@pragma('vm:prefer-inline')
T? maybeOf<T>(BuildContext context) => this(context.maybeBloomOf<T>());
