选择时单选图标消失 - 使用 Material UI

Radio icon disappears on selection - using Material UI

我用过materialUI的RadioGroup组件。选择单选按钮后,单选图标(圆形)消失,只剩下标签。

const [env,setEnv]=React.useState('Development')

<Grid container spacing={3}>
  <Grid item xs={3}>
    <Card className={classes.card} elevation={1}>
      <CardContent>
        <form noValidate onSubmit={handleSubmit}>
          <FormControl >
            <FormLabel >Select Environment</FormLabel>
            <RadioGroup value={env} onChange={(e) => setEnv(e.target.value)}>
              <FormControlLabel value='Development' control={<Radio />} label="Development" />
              <FormControlLabel value='Stage' control={<Radio />} label="Stage" />
              <FormControlLabel value='Production' control={<Radio />} label="Production" />
            </RadioGroup>
          </FormControl>
        </form>
      </CardContent>
    </Card>
  </Grid>
</Grid>

我这样试过: 我是这样做的:

const theme = {
  overrides: {
    MuiRadio: {
      root: {
        color: 'green',
      },
      colorSecondary: {
        '&$checked': {
          color: 'green',
        },
      },
    },
  },
}

const muiTheme = createMuiTheme(theme)

我现在可以根据需要更改单选图标的颜色:)
