如何在Expo上安装UI Kitten？

npm install @ui-kitten/components @eva-design/eva

import { mapping, light as lightTheme } from '@eva-design/eva';

export const evaConfig = {
  mapping: {
    ...mapping,
    // 在这里添加你需要的自定义组件映射
  },
  theme: {
    ...lightTheme,
    // 在这里添加你需要的自定义主题
  },
};

import React from 'react';
import { ApplicationProvider } from '@ui-kitten/components';
import { EvaIconsPack } from '@ui-kitten/eva-icons';
import { evaConfig } from './eva';

export default function App() {
  return (
    <ApplicationProvider {...eva} theme={evaConfig.theme} customMapping={evaConfig.mapping} iconPack={EvaIconsPack}>
      {/* 在这里编写你的应用程序 */}
    </ApplicationProvider>
  );
}
