How to use SVG-Uri in React-native or Expo?

问题

I downloaded the expo-svg-uri module to use the Svg image.

But the image doesn't come out right.

Code I failed:

  <View style={styles.container}>
    <SvgUri
      width="200"
      height="200"
      source={require("../../image/minigroup.svg")}
    />
  </View>

Failed Image

Original Image

this is my svgfile

I don't have a path value, I'm only drawing it all. Are you saying this is possible?

Please help us a lot. Thank you in advance.

回答1:

First

• Drag your svg file into this online tool SVGOMG
• Switch to the Markup tab.
• Copy d attribute of the path xml tag.

Second

• Render your svg file directly using react-native-svg

react-native-svg is already installed and linked if you're using expo

Example that would render Home icon:

<Svg
  width="20"
  height="20"
  viewBox="0 0 512 512" // Has to be the same of the original svg file
>
  <Path
    d="M208 448V320h96v128h97.6V256H464L256 64 48 256h62.4v192z"
    fill="red"
  />
</Svg>

This 'd save you as well the cost of loading and reading file ...
