Serialization into SVG XML (svg file) on native platforms

Goal

I need to save a preview image (as svg xml) of a dynamically generated SVG using react-native-svg.

Problem

While this works perfectly fine on web using svgRef?.current?.outerHTML or the serialization example in USAGE.md, it doesn't work properly on native. The problem starts as soon as the SVGR components are not hardcoded within the same component, but are composed from different (custom) components rendering them. The childToWeb function is not getting the SVG nodes and not traversing them, so the output shows nodes like RNSVGSvgView and RNSVGRect.

Question

• Is there any workaround/helper for this?
• Is there some way to implement svg (xml) export/serialization in react-native-svg - since it should be very similar to the web version?

Start with the serialization example in USAGE.md and inspect the referenced childToWeb function, especially how it handles SVG nodes from composed custom components. Determine how native output currently becomes RNSVGSvgView and RNSVGRect, then define a native serialization path whose done condition is valid SVG XML for dynamically composed SVGs.
