Not Getting anything back after calling Fetch API - React Native - react-native

Question

I am creating a React Native in which i am sending my Form's data to Backend Node.js using Fetch and that worked all fine but i cannot execute anything down after fetch api, even console.log is not running.
React-Native Code:
const PostData = () =>{
console.log("Posting");
//Sending Request to Node.js using Fetch API
fetch("http://192.168.0.107:3000/Adminsignup", {
//Setting Method
method:"POST",
//Setting Headers
headers:{
//Setting Content-Type
"Content-Type" : "application/json"
},
//Stringifying the email and password and storing it into body
body:JSON.stringify({
name,
gmail,
password,
retype
})
}).then(res=>{
console.log(res);
}).catch(err=>{
console.log(err);
})
}
.then and .catch of fetch api is not working.

Ok so your front-end code is all good and as u said that your backend is also working when you fire PostData() function, check if you are returning the response from backend.
Add this in your signup Route:
res.status(200).send({result:"Successfully got Response"})
Catch status in your front-end like this:
let final = await fetch("http://192.168.0.107:5000/studentSignup", {
//Setting Method
method:"POST",
//Setting Headers
headers:{
//Setting Content-Type
"Content-Type" : "application/json"
},
//Stringifying the email and password and storing it into body
body:JSON.stringify({name,gmail,password,retype})
})
const data = final.status;
if(data === 200)
{
navigation.navigate("Your Route");
}
