Google analytics on my React app with firebase SDK

The previous answer should be corrected like this:

import app from 'firebase/app';
import 'firebase/analytics';

app.initializeApp({
   //other config
  measurementId : process.env.REACT_APP_MEASUREMENT_ID,
  appId : process.env.REACT_APP_DEV_ID
})

//put inside your constructor
app.analytics()

This will solve the following error:

Error: firebase__WEBPACK_IMPORTED_MODULE_8___default.a.analytics is not a function react

I did't correctly initialized Analytics... With firebase it's not a track ID but a measurementId

import app from 'firebase/app';
import 'firebase/analytics';

app.initializeApp({
   //other config
  measurementId : process.env.REACT_APP_MEASUREMENT_ID,
  appId : process.env.REACT_APP_DEV_ID
})

//put inside your constructor
app.analytics()

This will solve the following error:

Error: firebase__WEBPACK_IMPORTED_MODULE_8___default.a.analytics is not a function react
