My source Code is looking thus

import { Button, Image, ImageBackground, StyleSheet, Text, TextInput, TouchableOpacity, View } from 'react-native'
import React, { useEffect, useState } from 'react';
import AsyncStorage from '@react-native-async-storage/async-storage';
import { Icon } from '@rneui/base'

const VirtualAccount = () => {

  const [virtualAcc, setvirtualAcc] = useState();
  const [account_number, setAccount_number] = useState("");
  const [bank_name, setBank_name] = useState("");
  

    sayAlert = () =>{
        alert('Text copy button is active');
    }

  
    getVirtualAccount = async () => {
      let token = await AsyncStorage.getItem('token');
      let email = await AsyncStorage.getItem('email');
  
      fetch(
        'https://webserver-migospay.onrender.com/api/user-serv/get-virtual-account/'+email,
        {
          method: 'GET',
          headers: {
            'Content-type': 'application/json',
            Authorization: `Bearer ${token}`,
          },
        },
      )
        .then(response => response.json())
        .then(responseJson => {
          setvirtualAcc(responseJson);
        });
    };

    useEffect(() => {
      //showdata();
      getVirtualAccount();
    });

  return (

        borderBottomWidth: 1,
        marginBottom: 30
    },
})

Checked all over the internet, I could not find something valuable. or what exactly must I do? Does it appear to be something I am missing?

    ==> Simply Add this line in you fetch function.

      .then(responseJson => {
          setBank_name(responseJson.bank_name)
          setvirtualAcc(responseJson);
        });

    ==> Update the TextInput Code.

    value={bank_name}

    you are getting array as response thats why you are getting an error, try this code

    fetch("https://webserver-migospay.onrender.com/api/userserv/getvirtualaccount/" +email,
{
method: "GET",
headers: {
  "Content-type": "application/json",
  Authorization: `Bearer ${token}`,
},
}
).then((response) => validateResponse(response));

const validateResponse = async (response) => {
var data = await response.json();
if (response.status === 200) {
setvirtualAcc(data[0]);
}
};
