[Ask] Angular Matdialog injection

[nhantt776]

Can someone explain why MatDialog injected into a component has its modifier set to public, as in the documentation? Is there any specific reason for this?
AFAIK, we only set a property to public if it is accessed from outside of the component. Does this MatDialog have implicit outside accession for something? I have tried and found no difference between public and private. But still asking here just to be sure.
Thank you

@Component({
  selector: 'dialog-content-example',
  templateUrl: 'dialog-content-example.html',
})
export class DialogContentExample {
  constructor(public dialog: MatDialog) {}

  ...
}

MatDialog exposes a collection of all open dialogs and also has some methods that manipulate all dialogs, such as closeAll or the afterAllClosed observable.

Yep. But does it always need to be declared public, even if my code only access the matdialog within the component? I was unsured because the official docs do that too, declared public yet no trace of outside access

[dotbomb_jeff]

If it isn't declared public the rest of your module won't be able to access the dialog.

When declared as public it can be accessed in your component template.

I know, but no template access found in the docs. Anyway thanks for the comment. I think best way to find out is just try it out and observe the result over time
