fromPrimitives method Null safety

  1. @override
TimeOfDay fromPrimitives(
  1. Object? data
)
override

Called by the RestorationMixin to convert the data previously retrieved from toPrimitives back into an object of type T that this property should wrap.

The object returned by this method is passed to initWithValue to restore the value that this property is wrapping to the value described by the provided data.

The method may be called multiple times throughout the life of the RestorableProperty. Whenever new restoration data has been provided to the RestorationMixin the property is registered to, either this method or createDefaultValue is called before initWithValue is invoked.

Implementation

@override
TimeOfDay fromPrimitives(Object? data) {
  final List<Object?> timeData = data! as List<Object?>;
  return TimeOfDay(
    minute: timeData[0]! as int,
    hour: timeData[1]! as int,
  );
}
