angular - Dynamically load a component inside a Material MatDialog

Question

Can anyone provide an example of how to dynamically load a component into a Material MatDialog?

What I would like to do is this: I will provide the MatDialog configuration data with a component Type which the dialog would then create an instance of and place inside it's mat-dialog-content area.

It appears I would need to use some combination of ng-template and viewContainerRef, but I do not know how to instantiate the provided component Type and insert into the desired area.

A simple example:

    <h2 mat-dialog-title>MyTitle</h2>
    <mat-dialog-content>
     <---- dynamically loaded component would be inserted here ---->
    </mat-dialog-content>

    <mat-dialog-actions>
      <button mat-button mat-dialog-close>Cancel</button>
      <button mat-button [mat-dialog-close]="true">Save</button>
    </mat-dialog-actions>

There are different options:

1) Built-in structural directive ngComponentOutlet

<ng-container *ngComponentOutlet="data.component"></ng-container> 

Example

2) Using angular material cdk. More precisely you can use PortalModule from secondary entry point @angular/cdk/portal

dialog.component.ts

import { ComponentPortal } from '@angular/cdk/portal';

@Component({...})
export class DialogDialog {

  portal: ComponentPortal<any>;

  constructor(...
    @Inject(MAT_DIALOG_DATA) public data: any) { }

  ngOnInit() {
    this.portal = new ComponentPortal(this.data.component);
  }
      

dialog.component.html

<ng-template [cdkPortalOutlet]="portal"></ng-template>

Example

3) Using Angular low-level API

dialog.component.ts

@Component({...})
export class DialogDialog {

  @ViewChild('target', { read: ViewContainerRef }) vcRef: ViewContainerRef;

  componentRef: ComponentRef<any>;

  constructor(
    ...
    private resolver: ComponentFactoryResolver,
    @Inject(MAT_DIALOG_DATA) public data: any) { }

  ngOnInit() {
    const factory = this.resolver.resolveComponentFactory(this.data.component);
    this.componentRef = this.vcRef.createComponent(factory);
  }


  ngOnDestroy() {
    if (this.componentRef) {
      this.componentRef.destroy();
    }
  }  
}

dialog.component.html

<ng-template #target></ng-template>
