My form is not showing in the emulator.

Good morning
I don't understand why my form is not showing in the emulator. Thank you to help me.

`import React, { useState } from 'react';
import { View, Text, TextInput, Button, StyleSheet, DatePickerAndroid } from 'react-native';

const AccountingForm = () => {
const [entryDate, setEntryDate] = useState(new Date());
const [entryAmount, setEntryAmount] = useState('');
const [entryComment, setEntryComment] = useState('');
const [exitAmount, setExitAmount] = useState('');
const [exitComment, setExitComment] = useState('');

const showDatePicker = async () => {
try {
const { action, year, month, day } = await DatePickerAndroid.open({
date: entryDate,
});
if (action !== DatePickerAndroid.dismissedAction) {
const newDate = new Date(year, month, day);
setEntryDate(newDate);
}
} catch ({ code, message }) {
console.warn('Cannot open date picker', message);
}
};

const onSubmit = () => {
console.log({
entryDate,
entryAmount,
entryComment,
exitAmount,
exitComment,
});
};
