使用Material-UI JSS和React定位正确的样式样式

Question

我是Material-UI的新手，也是React和Web开发的新手。我试图了解如何在MUI框架中使用Theme，createStyles和JSS。

我直接从文档here中获取了响应组件的代码。将样式放在文件顶部，该组件将按预期工作。但是，当我尝试定位图标以更改颜色时，没有任何东西呈现我选择的颜色。

这是单独文件中的JSS： 该文件称为：.src / shared / components / AppFrame / styles.js

import { createStyles } from '@material-ui/core';


const drawerWidth = 240;

export const styles = (theme) => createStyles({
  root: {
    display: 'flex',
  },
  appBar: {
    zIndex: theme.zIndex.drawer + 1,
    transition: theme.transitions.create(['width', 'margin'], {
      easing: theme.transitions.easing.sharp,
      duration: theme.transitions.duration.leavingScreen,
    }),
  },
  appBarShift: {
    marginLeft: drawerWidth,
    width: `calc(100% - ${drawerWidth}px)`,
    transition: theme.transitions.create(['width', 'margin'], {
      easing: theme.transitions.easing.sharp,
      duration: theme.transitions.duration.enteringScreen,
    }),
  },
  menuButton: {
    marginLeft: 12,
    marginRight: 36,
    color: theme.palette.common.white,
  },
  hide: {
    display: 'none',
  },
  drawer: {
    width: drawerWidth,
    flexShrink: 0,
    whiteSpace: 'nowrap',
    color: 'white',
  },
  drawerOpen: {
    paddingTop: 64,
    backgroundColor: theme.palette.primary.dark,
		color: theme.palette.common.white,
		width: drawerWidth,
    transition: theme.transitions.create('width', {
      easing: theme.transitions.easing.sharp,
      duration: theme.transitions.duration.enteringScreen,
    }),
  },
  drawerClose: {
    transition: theme.transitions.create('width', {
      easing: theme.transitions.easing.sharp,
      duration: theme.transitions.duration.leavingScreen,
    }),
    paddingBottom: 64,
    backgroundColor: theme.palette.primary.dark,
		color: theme.palette.common.white,
    overflowX: 'hidden',
    width: theme.spacing.unit * 7 + 1,
    [theme.breakpoints.up('sm')]: {
      width: theme.spacing.unit * 9 + 1,
    },
  },
  topToolbar: {
    display: 'flex',
    flexDirection: 'column',
    alignItems: 'center',
    justifyContent: 'flex-end',
    padding: '0 8px',
    margin: '24px',
    ...theme.mixins.toolbar,
  },
  toolbar: {
    display: 'flex',
    flexDirection: 'column',
    alignItems: 'center',
    justifyContent: 'flex-end',
    padding: '0 8px',
    ...theme.mixins.toolbar,
  },
  content: {
    flexGrow: 1,
    padding: theme.spacing.unit * 3,
  },
  listItem: {
    color: theme.palette.common.white,
  },
  icon: {
    color: theme.palette.common.white,
  }
});

组件文件如下： .src / shared / components / AppFrame / index.js

}

MiniDrawer.propTypes = {
  classes: PropTypes.object.isRequired,
  theme: PropTypes.object.isRequired,
};

export default withStyles(styles, { withTheme: true })(MiniDrawer);

以下是当前状态的屏幕截图：

问题是我试图使sideDrawer中的图标和文本显示为白色。非常感谢您提供任何技巧，建议或资源，以更好地了解样式如何与MUI配合使用。
