Getting lastVisionImage from the face detection

[kriefsacha]

Hi,

In the previous plugin we could do event.object.lastVisionImage to have the last image of the face detection which is mandatory in my project.

I was doing like:

const source = new ImageSource();

      if (isAndroid) {
        const bmp = event.object.lastVisionImage.getBitmap();
        source.setNativeSource(bmp);
      }
      else source.setNativeSource(event.object.lastVisionImage);

But now it doesn't work.

I tried

event.object.get("lastVisionImage");

but its undefined.

Thank you.

Just two other things:

• There was also a variable beepOnScan which was very helpful to have but we don't have any beep on scan here

• I commented #24 because it still doesn't work.

Added in f98e08d , you will need to enable it first using retrieveLatestImage = true then grab the imagesource from latestImage

Its not working @triniwiz , i got this error when putting retrieveLatestImage="true" in the MLKitView HTML ( i updated the plugins of course) :

Thank you for testing, the .8 has the final fix for that

[kriefsacha]

I'll test tomorrow and let you know (it's 1:24 am for me now). Thank you

Seems like working, opened a new ticket in @nativescript/firebase
