Is this a code style error? if so, you can disable that line according to your code styling library
If not, what you need to import to make it work is:
import "isomorphic-fetch";

Actually, the response.data should be response.json() after that it turn out to be code style error. Thank you for your response!
It might be better to add it in your .eslintrc config instead since the Fetch API is already included in React Native.

Hey if you are using new JS version ES6 then you can fetch your url request like this:
var params = {key:'value'}
var reqOpts = {}
reqOpts.method = 'POST'
reqOpts.headers['Accept'] = 'application/json'
reqOpts.headers['Content-Type'] = 'application/json'
reqOpts.body = JSON.stringify(params)
var url = 'YOUR_URL'
let response = await fetch(url, reqOpts)
return response.json()
.then((jsonData) => {
return jsonData
})
