You can do something like

import React, { useState } from "react";
import { Text, TextInput, View } from "react-native";

const App = () => {
  const [text, setText] = useState("");
  return (
    <View style={{ flexDirection: "row", borderWidth: 1, borderColor: "red" }}>
      {text.length > 0 && <Text style={{ color: "grey" }}>$</Text>}
      <TextInput
        style={{ color: "grey" }}
        placeholder="Type here to translate!"
        onChangeText={(newText) => setText(newText)}
        defaultValue={text}
      />
    </View>
  );
};

export default App;

If you want the text to be in the input all the time you either have to put it in the value and force it to be there. OR you have to use another element and position it over the input.

.ds { 
  position: absolute;
  margin-left: .6em;
  font-size: .8em;
  line-height: 1.5em;
}

.ds   input {
   padding-left: 1em;
}

<label for="x" >$</label><input type="text" id="x">
