For indefinitely loading problem:

Run on your real device. It must run and create account unless any coding error. You can also run on emulator by creating a new emulator having network setting selected option full. And also check the manifest file on your project if you have included internet user permission.

for anyone whose app is stuck at creating account, I solved the problem by deleting the google-services.json file, downloading it again and re-running the app. It changed the API key and fixed the problem for me. hopefully anyone might find this helpful.

Found solution for the error:I used the same code u used but I got error and then I tried to Google and find solutions, I found that using capital D in DataSnapShot I was able to use it correctly and also used snapshot instead of DataSnapShot in if condition...

This helped me to solve my problem, hope this comment will be useful to others who is trying to learn from this video...
