React Material UI - Autocomplete Component button after clear field button

I am trying to add a search button my Autocomplete Component on Material UI. So far I have been able to add the button however, it always appears before the clear button like below:

How can I set the InputProps such that the button will appear after the X.

So far I have:

<Autocomplete
    id="search-input"
    freeSolo                                   
    renderInput={(params) => (                    
        <TextField
            {...params} 
            placeholder={`...`} 
            margin="normal" 
            variant="outlined" 
            size="medium"
            InputProps={{
                ...params.InputProps,
                endAdornment: (
                <React.Fragment>                          
                    <IconButton size="small">
                        <SearchIcon />
                    </IconButton>    
                    {params.InputProps.endAdornment}               
                </React.Fragment>
                ),
            }}
        />  
    )}
/>

I have tried replacing the order of ...params.InputProps and the endAdornment but nothing changes.

When you inspect the elements within the Autocomplete in the dev tools, you'll see the following: an input representing the search area, the end adornment of the TextField which in your case is a button with a SearchIcon and a div with the class MuiAutocomplete-endAdornment which holds the clear icon. These appear on the screen in that order from left to right. These are all siblings within a div that has the CSS property: display: inline-flex. This means the siblings can be re-ordered using order. We want to show the elements in the following order from left to right: input, clear icon and search icon.

How

We can achieve this by overriding existing styles. Since the div which houses these three elements is a child of the root of the TextField component, we can apply the styling to the root class of the TextField.

1. Create class called textFieldRoot - you can call it whatever you want.

import { makeStyles } from "@material-ui/core/styles";

const useStyles = makeStyles({
  textFieldRoot: {
    "& > div.MuiAutocomplete-inputRoot[class*='MuiOutlinedInput-root']": {
      // default paddingRight was 39px since clear icon was positioned absolute
      paddingRight: "9px", 
      
      // Search icon
      "& button": {
        order: 3, // order 3 means the search icon will appear after the clear icon which has an order of 2
      },

      // Clear icon
      "& > div.MuiAutocomplete-endAdornment": {
        position: "relative", // default was absolute. we make it relative so that it is now within the flow of the other two elements
        order: 2,
      },
    },
  },
});

2. Apply the class to the root of the TextField

const classes = useStyles();

<Autocomplete
  id="search-input"
  freeSolo
  options={[]}
  renderInput={(params) => (
    <TextField
      {...params}
      classes={{
        root: classes.textFieldRoot, // apply class here
      }}
      placeholder={`...`}
      margin="normal"
      variant="outlined"
      size="medium"
      InputProps={{
        ...params.InputProps,
        endAdornment: (
          <React.Fragment>
            <IconButton size="small">
              <SearchIcon />
            </IconButton>
            {params.InputProps.endAdornment}
          </React.Fragment>
        ),
      }}
    />
  )}
/>

Result

Alternative

As you can see, it is a bit of work. I would consider using startAdornment instead of endAdornment in your InputProps to place the search icon at the front of the search bar.
