Creating the RadioButton.tsx component

import React from "react";
import {View, Text, SafeAreaView, StyleSheet, TouchableOpacity} from "react-native";

type Props = {
  isSelected: boolean;
  onPress: () => void;
};

export const RadioButton = (props: Props) => {
  const {isSelected, onPress} = props;

  return (
    <TouchableOpacity style={styles.outer} onPress={onPress}>
      {isSelected && <View style={styles.inner} />}
    </TouchableOpacity>
  )
};

const styles = StyleSheet.create({
  outer: {
    height: 24,
    width: 24,
    borderRadius: 12,
    borderWidth: 2,
    borderColor: "#000",
    alignItems: "center",
    justifyContent: "center",
  },
  inner: {
    height: 12,
    width: 12,
    borderRadius: 6,
    backgroundColor: "#000",
  },
});

Here's an example of using the <RadioButton>:

import {registerRootComponent} from "expo";
import React from "react";
import {Text, SafeAreaView, StyleSheet} from "react-native";
import {RadioButton} from "./components/RadioButton";

const App = () => {
  const [isSelected, setIsSelected] = React.useState(false);

  return (
    <SafeAreaView>
      <Text style={styles.header}>Welcome to One Minute Coding!</Text>

      <RadioButton isSelected={isSelected} onPress={() => setIsSelected(true)} />
    </SafeAreaView>
  );
};

export default registerRootComponent(App);

const styles = StyleSheet.create({
  header: {
    fontSize: 24,
    fontWeight: "bold",
    textAlign: "center",
    height: 50,
    width: '100%',
  },
});

Hope this helps! I would love to see how y'all make use of this - please share.
