registerGenericTypeWrapper static method

void registerGenericTypeWrapper(String baseTypeName, GenericTypeWrapperFactory factory)

Register a wrapper factory for a generic base type (additive).

Multiple factories can be registered for the same base type — each module contributes factory cases for its own types. Factories are checked in registration order during extractBridgedArg resolution; the first to return non-null wins.

The baseTypeName is the unparameterized type name (e.g., 'WidgetStateProperty'). The factory receives the raw value and the desired inner type argument string.

Idempotent: If the same factory (compared by identity) has already been registered for baseTypeName, the call is a no-op. Distinct factories for the same base type are still appended in registration order. This lets registerRelaxers() and similar generator-emitted blocks fire multiple times (e.g. on a second FlutterD4rt instance) without growing the per-key list.

Implementation

static void registerGenericTypeWrapper(
  String baseTypeName,
  GenericTypeWrapperFactory factory,
) {
  final identities =
      _genericTypeWrapperIdentities.putIfAbsent(baseTypeName, () => {});
  if (!identities.add(factory)) return;
  (_genericTypeWrappers[baseTypeName] ??= []).add(factory);
}
