如何在样式化组件中使用{withTheme}。任何人都可以提供实时示例

withTheme帮助您从组件道具中获取主题变量。定义主题时，通常可以在样式化的组件中使用它们，但是如果使用withThemeHOC定义组件，则可以在组件中使用这些变量。

// Define our button, with the use of props.theme
const Button = styled.button`
  color: ${props => props.theme.fg};
  border: 2px solid ${props => props.theme.fg};
  background: ${props => props.theme.bg};
`;

// Define our button, but with the use of component.props
const ThemeButton = (props) => (
  <button style={{background: props.theme.bg, color: props.theme.fg, border: `1px solid ${props.theme.fg}`}}>
  {`this button is using: ${props.theme.fg} and ${props.theme.bg}`}
  </button>
)

const ButtonWithTheme = withTheme(ThemeButton);

// Define our `fg` and `bg` on the theme
const theme = {
  fg: "palevioletred",
  bg: "white"
};

<ThemeProvider theme={theme}>
  <div>
    <Button>Default Theme</Button>
    <ButtonWithTheme></ButtonWithTheme>
  </div>
</ThemeProvider>
