# Summary Implement custom shadow nodes for nearly all `Svg` components. While it's a foundation for numerous upcoming changes, it currently addresses and resolves #2544. ## Test Plan There shouldn't be any noticeable changes, and everything should function as before, except that `onLayout` will now be triggered only once and with the correct dimensions. ## Compatibility | OS | Implemented | | ------- | :---------: | | iOS | ✅ | | MacOS | ✅ | | Android | ✅ | --------- Co-authored-by: Jakub Piasecki <jakubpiasecki67@gmail.com>
