To mitigate the effect of Observables with memory leak, this change clears
the `ChangeDetectorRef` when the `AsyncPipe` is destroyed. This avoids any

to verify that this change works correctly with promises that resolve _after_
the pipe has been destroyed.
Note: this is not marked as fix as `AsyncPipe` itself is _not_ leaking any

DEPRECATED:
It is now deprecated to provide *both* `AbstractControlOption`s and an async validators argument to a FormControl. Previously, the async validators would just be silently dropped, resulting in a probably buggy forms. Now, the constructor call is deprecated, and Angular will print a warning in devmode.

Consider a typed group for storing contact information:
```
declare interface ContactControls {
name: FormControl<string|null>;
}
contactForm: FormGroup<ContactControls> = ...;
saveForm(form: FormGroup<ContactControls>) {
service.newContact(contactForm.value);
}
```
What should be the type of `newContact`? The answer, of course, is the value type:
```
declare interface Contact {
name: string|null;
}
class ContactService {
newContact(c: Contact) {}
}
```
This is quite redundant, and therefore, we should allow the value type to be generated automatically. We already have the helper types to do this -- we just need to document and export them. Then, this becomes possible:
```
class ContactService {
newContact(c: RawValue<FormGroup<ContactControls>>) {}
}
```

This commit adds the `ngDevMode` check to tree-shake away an error message string (which also retains a reference to an extra function).
PR Close#45994
The `inject()` function was introduced with Ivy to support imperative
injection in factory/constructor contexts, such as directive or service
constructors as well as factory functions defined in `@Injectable` or
`InjectionToken`. However, `inject()` in a component/directive constructor
did not work due to a flaw in the logic for creating the internal factory
for components/directives.
The original intention of this logic was to keep `ɵɵdirectiveInject` tree-
shakable for applications which don't use any component-level DI. However,
this breaks the `inject()` functionality for component/directive
constructors.
This commit fixes that issue and adds tests for all the various cases in
which `inject()` should function. As a result `ɵɵdirectiveInject` is no
longer tree-shakable, but that's totally acceptable as any application that
uses `*ngIf` or `*ngFor` already contains this function. It's possible to
change how `inject()` works to restore this tree-shakability if needed.

The Testability-related logic was refactored in https://github.com/angular/angular/pull/45657 to become tree-shaking-friendly: it was decoupled from the core providers of the `BrowserModule`.

With typed forms, all `FormControl`s are nullable by default, because they can be reset to `null`. This behavior is possible to change by passing the option `initialValueIsDefault: true`. However, in a large form, this is extremely cumbersome, as the option must be repeated over and over. Additionally, it is not possible to take full advantage of `FormBuilder`, since `FormBuilder.group` and `FormBuilder.array` will produce nullable controls.
This PR introduces a new accessor `FormBuilder.nonNullable`, which produces *non-nullable* controls. Specifically, any call to `.control` will produce controls with `{initialValueIsDefault: true}`, and calls to `.array` or `.group` that implicitly build inner controls will have the same effect.
```ts
let nfb = new FormBuilder().nonNullable;
let name = nfb.group({who: 'Alex'}); // FormGroup<{who: FormControl<string>}>
name.reset();
console.log(name); // {who: 'Alex'}
```

All router events now have a `type` property with a string name identifying the specific type of the event.
The `type` property can be used to perform TypeScript type narrowing using an `if` statement, `switch`
statement, or similar. This removes the need to perform `instanceof` checks but still allows them if
preferred. An `instanceof` check requires the use of the event class value which may not be available
or preferred in certain situations.
The Router's `enableTracing` option is also now guarded with the `ngDevMode` flag which combined with
the use of a new `stringifyEvent` function allows the tree-shaking of the string generation code for
each router event class. However, the original `toString` class methods are still present to prevent
a potential breaking change. As a result, full benefits of the tree-shaking potential will not be realized
until they are removed.

PR Close#45837
In AOT compilations, the `strictInjectionParameters` compiler option can
be enabled to report errors when an `@Injectable` annotated class has a
constructor with parameters that do not provide an injection token, e.g.
only a primitive type or interface.
Since Ivy it's become required that any class with Angular behavior
(e.g. the `ngOnDestroy` lifecycle hook) is decorated using an Angular
decorator, which meant that `@Injectable()` may need to have been added
to abstract base classes. Doing so would then report an error if
`strictInjectionParameters` is enabled, if the abstract class has an
incompatible constructor for DI purposes. This may be fine though, as
a subclass may call the constructor explicitly without relying on
Angular's DI mechanism.
Therefore, this commit excludes abstract classes from the
`strictInjectionParameters` check. This avoids an error from being
reported at compile time. If the constructor ends up being used by
Angular's DI system at runtime, then the factory function of the
abstract class will throw an error by means of the `ɵɵinvalidFactory`
instruction.
In addition to the runtime error, this commit also analyzes the inheritance
chain of an injectable without a constructor to verify that their inherited
constructor is valid.

`importProvidersFrom` provides a bridge from the world of NgModule-based DI
configuration to the new, "standalone" world of direct providers and
environment injectors. Early user feedback suggested some confusion around
where this function was supposed to be used, particularly around importing
NgModule-based providers into standalone component `providers` arrays, which
is not the intended use. This confusion is exacerbated by the fact that due
to the unified `Provider` type, this kind of misconfiguration was happily
accepted by the type system.
This commit changes the return type of `importProvidersFrom` to wrap the
returned providers in an opaque type that prevents them from being used in
component provider contexts. This, together with stronger documentation
around the purpose and functionality of `importProvidersFrom`, should
address some of the above confusion.

* Adding a backwards-compatibility layer for calls to `updateTypeParameterDeclaration`.
* Making `LView` generic in order to make it easier to type the context based on the usage. Currently the context can be 4 different types which coupled with stricter type checking would required a lot of extra casting all over `core`.
* Fixing a bunch of miscellaneous type errors.
* Removing assertions of `ReferenceEntry.isDefinition` in a few of the language service tests. The field isn't returned by TS anymore and we weren't using it for anything.
* Resolving in error in the language service that was caused by TS attempting to parse HTML files when we try to open them. Previous TS was silently setting them as `ScriptKind.Unknown` and ignoring the errors, but now it throws. I've worked around it by setting them as `ScriptKind.JSX`.

Similarly to the symmetry being strengthened between children and loadChildren,
a new loadComponent property will be introduced as the asynchronous version of component.
This will allow for direct single-component lazy loading:
```
{path: 'lazy/a', loadComponent:
() => import('./lazy/a.component').then(m => m.ACmp)},
{path: 'lazy/b', loadComponent:
() => import('./lazy/b.component').then(m => m.BCmp)},
```
This option requires that the component being loaded is standalone and
is implemented as a runtime check.
Other notes:
* Components are not loaded until all guards and resolvers complete.
* Loading the component is included in the function passed to the router
preloading strategy
* `RouteConfigLoadStart` and `RouteConfigLoadEnd` events emit at the
start and end of the component loading
* `CanLoad` guards _do not_ apply to `loadComponent`. `canActivate`
should be used instead, just like you would do if it were simply
`component` instead.

This commit expands the `LoadChildrenCallback` to accept returning `Routes`
in addition to the existing `NgModule` type. In addition, it adds a
check to ensure these loaded routes all use standalone components.
The components must be standalone because if they were not,
we would not have the required `NgModule` which the component is declared in.
Existing API:
```
{path: 'lazy/route', loadChildren: import('./lazy').then(m => m.LazyModule)}
@NgModule({
imports: [
ExtraCmpModule,
RouterModule.forChild([
{path: 'extra/route', component: ExtraCmp},
]),
],
})
export class LazyModule {}
```
The new API for lazy loading route configs with standalone components
(no NgModule) is to expand `loadChildren` to allow returning simply a `Routes` array.
```
// parent.ts
{
path: 'parent',
loadChildren: () => import('./children').then(m => m.ROUTES),
}
// children.ts
export const ROUTES: Route[] = [
{path: 'child', component: ChildCmp},
];
```
Note that this includes minimal documentation updates. We need to
include a holistic update to the documentation for standalone components
in the future that includes this feature.
