value property
override
Returns the value of the property either from cache or by invoking a ComputePropertyValueCallback.
If an exception is thrown invoking the ComputePropertyValueCallback, value returns null and the exception thrown can be found via the exception property.
See also:
- valueToString, which converts the property value to a string.
Implementation
@override
T get value {
_maybeCacheValue();
return _value;
}
