wrappers library

Argument wrappers for values passed into a zone.

Some values have to be wrapped before they cross into patch code — most commonly a BuildContext:

SwapZone(
  zone: headlineZone,
  args: [$BuildContext.wrap(context)],
  builder: (context) => const Text('...'),
)

How a value has to cross depends on the engine the patch was built with:

knowa_kernel takes ordinary host objects — pass the value as it is.
dart_eval dispatches through its own boxes. int, double and bool cross unwrapped provided the patch declares the concrete type (int v, not num v), because that compiles to a direct call. A String or a List must be wrapped — $String(...), $List.wrap([...]) — as soon as the patch reads a member of it, and so must everything else: a BuildContext becomes $BuildContext.wrap(context).

Getting it wrong is not silent, but it is late: the zone throws on the device, reports itself through KnowaConfig.onEvent, and falls back to the code the app shipped with. knowa patch warns about the common case. Every combination is pinned down in test/zone_arguments_test.dart.

Wrapping does not tie a zone to one engine. The wrapping is compiled into the shipped binary and cannot be changed by a patch, so the kernel engine unwraps what it is given — a zone written for dart_eval can be taken over by a KIR patch without a store release, which is the point of letting the payload choose its engine.

Re-exported here so a host app never has to depend on the interpreter package directly. That keeps the interpreter an implementation detail of this SDK: replacing or renaming it later is then a change here, not a change in every app that uses Knowa.
