Add Firebase Performance Monitoring HTTP Metrics to all Axios requests (RNFB v5). This is taken from a guide on the new React Native Firebase website (not yet ready for public use).

firebase-perf-axios.js

import axios from 'axios';
import firebase from 'react-native-firebase';

axios.interceptors.request.use(async function (config) {
  const httpMetric = firebase.perf().newHttpMetric(config.url, config.method);
  config.metadata = { httpMetric };

  // add any extra metric attributes if needed
  // await httpMetric.putAttribute('userId', '12345678');

  await httpMetric.start();
  return config;
});

axios.interceptors.response.use(async function (response) {
  const { httpMetric } = response.config.metadata;

  // add any extra metric attributes if needed
  // await httpMetric.putAttribute('userId', '12345678');

  await httpMetric.setHttpResponseCode(response.status);
  await httpMetric.setResponseContentType(response.headers['content-type']);
  await httpMetric.stop();

  return response;
}, async function (error) {
  const { httpMetric } = error.config.metadata;

  // add any extra metric attributes if needed
  // await httpMetric.putAttribute('userId', '12345678');

  await httpMetric.setHttpResponseCode(error.response.status);
  await httpMetric.setResponseContentType(error.response.headers['content-type']);
  await httpMetric.stop();

  return Promise.reject(error);
});

I need to record the performance by screen wise.
Example

Home Screen >
A api called responseCode: 200, responseTime: 428.8650ms,
B api called responseCode: 200, responseTime: 118.8650ms

is this possible to track on the firebase. Currently api name passing through the headers
--header 'domain:''
--header 'product:''
--header 'business-flow: ''
--header 'exalt-api: USER_CREATE'
--header 'operation-flow: CREATE_FLOW'
--header 'Content-Type: application/json

currently im getting the api name. with below code.
const apiName = response.config.headers['exalt-api'].toLowerCase();

1. Need to know how i can pass the apiName according to the screen wise
2. How to show api name as a custom attribute on the firebase performance (Network).

Any luck? can't seem to have each of the API calls logged
