# UnusedProperty
2022-12-22 15:43:55 +01:00
Emitted when `--find-dead-code` is turned on and Psalm cannot find any uses of a
private property.
Properties used in constructor only are considered unused. Use normal variables instead.
2022-12-22 15:43:55 +01:00
If this property is used and part of the public API, annotate the containing
class with `@psalm-api`.

public function getFoo(): ?string {
return $this->foo;

$a = new A();
echo $a->getFoo();
