# UnusedProperty
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.
If this property is used and part of the public API, annotate the containing
class with `@psalm-api`.
```php
<?php
class A {
/** @var string|null */
private $foo;
/** @var int|null */
private $bar;
public function getFoo(): ?string {
return $this->foo;
}
}
$a = new A();
echo $a->getFoo();
```
