Photo_view: RenderRepaintBoundary.toImage() cannot get the image from PhotoView

[RustFisher]

Using RepaintBoundary with GlobalKey to take screenshot for PhotoView and output png file.

The output png file is only black.

Could you pls post an example with RepaintBoundary?

It is a flutter bug, not PhotoView bug.

I'm using Android studio. Here is the config. (Haven't tried release apk yet)

"flutter build apk" --enable-software-rendering
How do I add this parameter ?

Same problem. Don't know how to "--enable-software-rendering" while release apk.
