Nette Framework extension for PHPStan

This extension provides following features:

Nette\ComponentModel\Container::getComponent() knows type of the component because it reads the return type on createComponent* (this works best in presenters and controls)
Nette\DI\Container::getByType and createInstance return type based on first parameter (Foo::class).
Nette\Forms\Container::getValues return type based on $asArray parameter.
Nette\ComponentModel\Component::lookup return type based on $throw parameter.
Nette\Application\UI\Component::getPresenter return type based on $throw parameter.
Dynamic methods of Nette\Utils\Html
Magic Nette\Object and Nette\SmartObject properties
Event listeners through the on* properties
Defines early terminating method calls for Presenter methods to prevent Undefined variable errors
Understand the exact array shape coming from Nette\Utils\Strings::match() and Nette\Utils\Strings::matchAll() based on pattern

It also contains these framework-specific rules (can be enabled separately):
