I am able to get the data onDismiss() but I would like to do it without exiting the popover.

Below is the code snippet I tried onDismiss() and it worked.

async presentPopover(opts) {

    console.log(opts);
    const popover = await this.popoverController.create({
      component: RouteDetailsPopoverComponent,
      componentProps: {
        viewType: this.viewType
      },
      event: opts.event
    });

    popover.onDidDismiss()
    .then((result) => {
      console.log(result['data']);
      this.viewType = result['data'];
    });

    return await popover.present();
}

And here's the popover component

changeRouteDetailView(mode: View) {
    this.viewType = mode;
    this.popCtrl.dismiss(this.viewType);
}
