objectRuntimeType function Null safety
Framework code should use this method in favor of calling toString
on
Object.runtimeType.
Calling toString
on a runtime type is a non-trivial operation that can
negatively impact performance. If asserts are enabled, this method will
return object.runtimeType.toString()
; otherwise, it will return the
optimizedValue
, which must be a simple constant string.
Implementation
String objectRuntimeType(Object? object, String optimizedValue) {
assert(() {
optimizedValue = object.runtimeType.toString();
return true;
}());
return optimizedValue;
}
