Creating Dialog.alert inside .then((result) not working

Hi!

When I use the scanner and the code scanned did not match a param an alert is triggered to let the user know the scan is wrong. So in the result I have the following line to test:

.then((result) => {
      const alertOptions = {
        title: 'Warning',
        message: 'Something terrible has happened.',
        okButtonText: 'Okay',
        cancelable: false // [Android only] Gets or sets if the dialog can be canceled by taping outside of the dialog.
      }

      Dialogs.alert(alertOptions).then(() => {
        console.log('Ok chosen!')
      })
    });

This bit of code results in the next warning/error:

Warning: Attempt to present <UIAlertController: 0x10309c000> on <QRCodeReaderViewController: 0x102468590> whose view is not in the window hierarchy!

No alert is showing up which is obvious if you look at the warning/error.

I’m using: “@angular/core”: “~11.2.5”, “@nativescript/core”: “8.0.2”, “nativescript-barcodescanner”: “^4.1.0”,

Anyone a suggestion how to fix this? Is it a scanner issue or do I do something wrong?

Thanks in advance for any answer!!

Got it, thank you!

presentInRootViewController: true

This was the issue… I’ve copied the code from GitHub and your last message got me thinking about the modal…

it looks like

Fullscreen: true or Fullscreen: false

is not doing anything but deleting excluding the “presentInroot” showed me an alert without any warning or error.

Maybe I’ll look into that in te future if I got some time and know how to debug the plugin but for now its ok for me.

It’s up to you if you want this issue to be open to work on it later or close it.

Kind regards.
