Thanks. It's worked. I add google-services.json and changed applicationId in build.gradle and now i'ts worked perfectly.

@Reresize Hi, thanks for opening issue. In that case, i've never got those errors. how about when you create new project and install some dependencies using pub get ? does this issue appears or not.
I think this issue is related to this flutter/flutter#21319
Thanks

Ah, i see the problem. I forgot to add firebase tutorial on readme. I'm using firebase to detect user count with analytics.
The google-services.json is missing, it because i didn't public my google-service.json. You can add your google-service.json by following this tutorial https://firebase.google.com/docs/flutter/setup.
Or If you won't to use firebase analytics, you can follow this tutorial :

1. Go to android/build.gradle and delete classpath 'com.google.gms:google-services:4.3.3'
2. Go to android/app/build.gradle and delete apply plugin: 'com.google.gms.google-services' and implementation 'com.google.firebase:firebase-analytics:17.2.2'

Hope this works
