How should the superclass constructor of `MatDialog` be invoked when working with multiple classes?

When dealing with multiple features in my ts file, I decided to split them into separate classes.

   constructor(
           
        ) {
            super(MatDialog);
        }

Encountered error:

Argument of type 'typeof MatDialog' is not assignable to parameter of type 'MatDialog'.

Extending class:

export class AddClicnicComponent {
    popTableSchema;
    tableSchema;
    @ViewChild('popupTemp', { static: true })
    popupTemp: TemplateRef<HTMLAllCollection>;

    constructor(public dialog: MatDialog) {
        console.log('I am being called by the superclass');
    }
    handleAddClinic() {
        this.popTableSchema = { ...this.tableSchema };
        this.openDialog(this.popupTemp);
    }
    openDialog(templateRef: TemplateRef<HTMLAllCollection>) {
        const dialogRef = this.dialog.open(templateRef);
        dialogRef.afterClosed().subscribe((result) => {
            console.log(`Dialog result: ${result}`);
        });
    }
}

What exact parameters do I need to send with super? Is it possible to avoid passing parameters altogether?

Answer №1

It is recommended to begin by including the MatDialog dependency in the constructor, and subsequently transferring that instance to the super method. Here is an example:

constructor(public dialog: MatDialog) {
            super(dialog); //The instance (i.e. dialog) is passed here instead of the type MatDialog
        }

Answer №2

Make sure you are passing the object instance to the parent class, not just the class definition.
