Using CSS dimensions in react-native - react-native

In normal css, dimensions like px, %, rem etc. works perfectly. But in react native, it throws an error.
Are there any possible ways to use these dimensions directly in react-native ?

REMs are a way of setting font-sizes based on the font-size of the root HTML element.
react native is purely works on pixels. Different mobile screens have different pixel ratio .
pixelRatio documentation in react native
if you want text normalization in react native
use my custom function in my open source project.

Suppose you want the width to be 50% of the View so you can do <View style={{width:'50%'}} /> .
Hope its clear. Feel free for doubts.

How do you move the position of components like text in react native?

I'm coding in React Native and I want to move text positions and images without using bottom, top, left and right. These components only work for my screen only and will align incorrectly on other devices. Can someone show me how to move the components to custom positions on my app?
without seeing your code or how you are using it my first suggestion would be to try and use padding. But here's a list of layout props in React Native https://reactnative.dev/docs/layout-props

Is there a way to use SVG animation based on SMIL in React Native?

I'm writing a mobile application using React Native, and we have a bunch of nice animations done in SVG, by using so-called SMIL commands inside this SVG(tags like "animate" etc).
I was trying to find a way to use those animations but to my knowledge none of the libraries that I was able to find(including react-native-svg, react-native-svg-animations) able to do that.
I also checked this link: https://react-svgr.com/playground/?native=true which claim to transform SVG code to JSX, and it said that:
"/* SVGR has dropped some elements not supported by react-native-svg: style, animate */"
Is there anyone who was able to find efficient way to run these animations on React Native?
Thanks in advance!

Unfortunately, there's no easy way to do this with React Native. The best solution I've found is by defining SVGs and using react-native-svg, which supports touch events. If you're using Expo, then it is already preinstalled and can be imported like import { Svg } from 'expo'; const { Circle, Rect } = Svg;.
Alternatively, you may be able to use a WebView (mirror) and CSS masking to achieve your desired result.

onPress not working in Victory chart in React Native while running in android

React Native Victory charts : onPress or onPressIn is not triggered in android. however it is OK in iOS.
Can anyone help me regarding this.
I found out (by reading other stackoverflow issues addressing similar problems) that wrapping the whole VictoryChart in an <Svg>...</Svg> solves this issue on Android and on the other hand keeps the onPress functionality on iOS. The only thing I realized on top was that I had to give the Svg a style={{height: XXX}} where XXX is the same height than the VictoryChart has. Otherwise the wrapping Svg would be gigantic high.
