How to override styles for material-ui TextField component without using the MUIThemeProvider?

How would I hide / remove the underline in a TextField component without using the following code:

const theme = createMuiTheme({
  overrides: {
    MuiInput: {
      underline: {
        '&:hover:not($disabled):before': {
          backgroundColor: 'rgba(0, 188, 212, 0.7)',
        },
      },
    },
  },
});

I would like to do it with props and according to the docs: https://material-ui.com/api/input/

I should be able to change the underline prop, but it does not work.

This is how you do it:

<TextField
    id="name"
    label="Name"
    value={this.state.name}
    margin="normal"
    InputProps={{disableUnderline: true}}
/>

How did I figure it out?

You have linked to the Input documentation, which does indeed have a disableUnderline prop.

However, you are using a TextField component:

It's important to understand that the text field is a simple abstraction on top of the following components:

• FormControl
• InputLabel
• Input
• FormHelperText

If you look at the list of available props for TextField:

InputProps - object - Properties applied to the Input element.
