How to create flutter tests using firestore emulator

So i have installed and setup firestore emulator on my machine and i can run javascript and typescript tests, but what i want to do is to turn this javascript test setup to code in flutter so i can test my functions

Here is the javascript setup

const firebase = require("@firebase/testing");
const fs = require("fs");

/*
 * ============
 *    Setup
 * ============
 */
const projectId = "firestore-emulator-example";
const firebasePort = require("../firebase.json").emulators.firestore.port;
const port = firebasePort /** Exists? */ ? firebasePort : 8080;
const coverageUrl = `http://localhost:${port}/emulator/v1/projects/${projectId}:ruleCoverage.html`;

const rules = fs.readFileSync("firestore.rules", "utf8");

/**
 * Creates a new app with authentication data matching the input.
 *
 * @param {object} auth the object to use for authentication (typically {uid: some-uid})
 * @return {object} the app.
 */
function authedApp(auth) {
  return firebase.initializeTestApp({ projectId, auth }).firestore();
}

/*
 * ============
 *  Test Cases
 * ============
 */
beforeEach(async () => {
  // Clear the database between tests
  await firebase.clearFirestoreData({ projectId });
});

before(async () => {
  await firebase.loadFirestoreRules({ projectId, rules });
});

after(async () => {
  await Promise.all(firebase.apps().map(app => app.delete()));
  console.log(`View rule coverage information at ${coverageUrl}\n`);
});

Any tutorial or help on how to start doing it would mean a lot.
