• [X] I understand that incomplete issues (e.g. without reproduction) are closed.

Adding this debug code I see getBoundingBox has some information:

Thank you for reporting this. I will take a closer look the next days.

The readBarcodesFromImage(...) method does not yet support the calculation of cornerPoints. I have now documented this (see here) and converted the issue into a feature request. PRs are welcome.

@ebarooni Feel free to work on this issue. There is already a PR which you can use as inspiration: https://github.com/capawesome-team/capacitor-mlkit/pull/100
