Häufige Annahme
Extending Equatable automatically includes instance properties in toString() output without requiring explicit configuration or debug assert flags.
So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.
Contract
- Calling toString() on an Equatable instance without explicit stringify overrides returns only the runtimeType string 'DefaultItem' rather than 'DefaultItem(a, 42)' when assertions are not enabled.
- Explicitly setting EquatableConfig.stringify = true causes toString() to include properties regardless of assertion mode.
- Overriding get stringify => true on an Equatable class includes properties even when EquatableConfig.stringify is false.
