react-native - 如何在 react-native 中创建渐变文本

Question

我想在 react-native 中创建具有线性渐变颜色的文本，但找不到合适的方法或包来执行此操作。我尝试使用这个包:https://github.com/iyegoroff/react-native-text-gradient .但是，在尝试使用 expo 运行示例时，它给了我以下错误:

TypeError: Cannot read property 'x' of undefined

你能帮我解决这个问题还是找到另一种在 react-native 中创建渐变文本的方法？

使用 [ react 原生 svg][1]

[1]:https://github.com/react-native-community/react-native-svg例如:

 import Svg, {
  LinearGradient,
  Text,
  Defs,
  Stop,
  TSpan
} from 'react-native-svg';
<Svg viewBox="0 0 300 300" height="300"
             width="300">
          <Defs>
            <LinearGradient id="rainbow" x1="0" x2="0" y1="0" y2="100%" gradientUnits="userSpaceOnUse" >
              <Stop stopColor="#FF5B99" offset="0%" />
              <Stop stopColor="#FF5447" offset="20%" />
              <Stop stopColor="#FF7B21" offset="40%" />
              <Stop stopColor="#EAFC37" offset="60%" />
              <Stop stopColor="#4FCB6B" offset="80%" />
              <Stop stopColor="#51F7FE" offset="100%" />
            </LinearGradient>
          </Defs>
          <Text fill="url(#rainbow)">
            <TSpan
              fonSize="72"
              x="0"
              y="72"
            >
              gradient
            </TSpan>
            <TSpan fonSize="72" x="0" dy="72">text</TSpan>
            <TSpan fonSize="72" x="0" dy="72">all up in here</TSpan>
          </Text>
        </Svg>
