@nnixaa I have included:

import { NbToastrModule } from "@nebular/theme";

declarations: [ ToastrComponent ]; imports: [ NbToastrModule.forRoot(), ] providers: [ NbToastrService ],

How to use and where to use this following lines: const toastRef: NbToastRef = this.toastrService.show(...); toastRef.close();
