Material-UI 中依赖道具的切换颜色

Question

以下代码改编自 Material-UI 文档 customizing Switch 允许将开关颜色设置为蓝色：

import React from 'react'

import Switch from '@material-ui/core/Switch'
import {withStyles} from '@material-ui/core/styles'


const ColoredSwitch = withStyles({
  switchBase: {
    '&$checked': {
      color: 'blue',
    },
  },
  checked: {},
  track: {},
})(Switch)

但是当尝试调整它以便可以通过组件属性设置颜色时，它就是行不通。以下代码（仅是伪动态的）事件呈现为默认开关：

const ColoredSwitch = withStyles({
  switchBase: {
    '&$checked': {
      color: props => 'blue',
    },
  },
  checked: {},
  track: {},
})(Switch)

我想我一定是做错了什么，但不知道是什么。

如果必须使用 withStyles HOC，请按照此示例传递道具：https://material-ui.com/styles/basics/#adapting-the-higher-order-component-api

const ColoredSwitch = withStyles({
  switchBase: {
    "&.Mui-checked": {
      color: (props) => props.customchecked
    }
  },
  checked: {},
  track: {}
})((props) => {
  const { classes, ...other } = props;
  return <Switch classes={{ switchBase: classes.switchBase }} {...other} />;
});

您也可以使用makeStyles

const useStyles = makeStyles({
  switchBaseChecked: {
    "&.Mui-checked": {
      color: (props) => props.color
    }
  }
});

export default function Switches() {
  const props = { color: "green" };
  const classes = useStyles(props);
  return (
    <Switch
      color="primary"
      classes={{
        checked: classes.switchBaseChecked
      }}
    />
  );
}
