# MissingConstructor
|
|
|
|
Unitialized properties are statically hard to analyze. To prevent mistakes, Psalm will enforce that all properties should be initialized.
|
|
|
|
It does that through [PropertyNotSetInConstructor](./PropertyNotSetInConstructor.md) and this issue.
|
|
|
|
Psalm will then assume every property in the codebase is initialized.
|
|
|
|
Doing that allows it to report missing initializations as well as [RedundantPropertyInitializationCheck](./RedundantPropertyInitializationCheck.md)
|
|
|
|
This issue is emitted when non-null properties without default values are defined in a class without a `__construct` method
|
|
|
|
If your project relies on having uninitialized properties, it is advised to suppress this issue, as well as [PropertyNotSetInConstructor](./PropertyNotSetInConstructor.md) and [RedundantPropertyInitializationCheck](./RedundantPropertyInitializationCheck.md).

<?php

class A {

/** @var string */
|

public $foo;

}
|

```
