Commonly assumed
An Equatable object's toString method only outputs its properties if stringify is locally overridden to true or if EquatableConfig.stringify is explicitly enabled.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- By default in debug mode (assertions enabled), printing an Equatable instance that does not override stringify prints its property values because EquatableConfig.stringify defaults to true.
- assert(AutoStringify(42).toString() == 'AutoStringify(42)');
