WrapperExistsCheck typedef
WrapperExistsCheck =
bool Function()
Signature for an injected "does CWD have a consumer wrapper?" check.
A consumer wrapper is either bin/dispatcher.dart (the canonical name
emitted by dart run fluttersdk_artisan install) or bin/artisan.dart
(the legacy name still accepted for backward compatibility with
hand-curated wrappers).
Defaults to the real FS lookup (defaultConsumerWrapperExists); tests inject a deterministic stub.
Implementation
typedef WrapperExistsCheck = bool Function();
