Which @angular/* package(s) are the source of the bug?

common

Is this a regression?

No (it's like this since forever, the ngComponentOutlet directive was created before angular could check for strictNullChecks)

Description

<ng-container *ngComponentOutlet="null"></ng-container> throws

 error TS2322: Type 'null' is not assignable to type 'Type<any>'.

even though the directive is capable of handling falsy values: https://github.com/angular/angular/blob/master/packages/common/src/directives/ng_component_outlet.ts#L99

This forces you to use any if you use ngComponentOutlet & strict null checks to render a component that is optional.

Please change

- @Input() ngComponentOutlet!: Type<any>;
+ @Input() ngComponentOutlet?: Type<any>;

in https://github.com/angular/angular/blob/master/packages/common/src/directives/ng_component_outlet.ts#L73

Please provide the environment you discovered this bug in (run ng version)

angular 13.3.4
