import { DialogRef } from '@angular/cdk/dialog';
/**
 * Reference to a dialog opened via {@link DialogService.open}. Returned to the opener and
 * also injectable by the opened content component/template (to close with a result).
 *
 * Wraps the CDK `DialogRef`. `closed` is a `Promise` that resolves with the close result — or
 * `undefined` when the dialog is dismissed (close button / Escape / backdrop). CDK emits its
 * own `closed` synchronously inside `close()`, which can trigger `ExpressionChangedAfter-
 * ItHasBeenChecked` (NG0100) when a subscriber updates view state; a Promise defers to a
 * microtask, so handlers are change-detection safe. Using a Promise (rather than an rxjs
 * Observable) also keeps the library rxjs-free and mirrors ng-bootstrap's `NgbModalRef.result`.
