open a dialog and catch "afterClosed" event

[rherl23]

How can I open a dialog window and catch the "afterClosed" event from the parent component and receive a response from the dialog that was opened?
example:

let dialogRef = dialog.open(UserProfileComponent, {
height: '400px',
width: '600px',
});

dialogRef.afterClosed().subscribe(result => {
console.log(`Dialog result: ${result}`); // Pizza!
});
