Could not determine the dependencies of task ':app:preDebugBuild' - firebase

Question

I am build an app with firebase dependencies before creating an app i have done the firebase configuration and added firebase dependencies in pubspec.yaml. But when i run the app i got some errors.
FAILURE: Build failed with an exception.
* What went wrong:
Could not determine the dependencies of task ':app:preDebugBuild'.
> In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[15.0.
1]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.
Dependency failing: com.google.android.gms:play-services-flags:15.0.1 -> com.google.android.gms:play-services-basement#[
15.0.1], but play-services-basement version was 16.0.1.
The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art
ifact with the issue.
-- Project 'app' depends on project 'firebase_auth' which depends onto com.google.firebase:firebase-auth#16.0.2
-- Project 'app' depends on project 'firebase_core' which depends onto com.google.firebase:firebase-core#16.0.4
-- Project 'app' depends on project 'firebase_database' which depends onto com.google.firebase:firebase-database#15.+
For extended debugging info execute Gradle from the command line with ./gradlew --info :app:assembleDebug to see the dep
endency paths to the artifact. This error message came from the google-services Gradle plugin, report issues at https://
github.com/google/play-services-plugins and disable by adding "googleServices { disableVersionCheck = false }" to your b
uild.gradle file.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

The Problem occur when the dependencies cannot download from jcenter server. change your network connection follows flutter clean and try again
you can still work in debug mode
flutter run --debug will work
or you can goto File > Settings>Build,Execution,Deployment>Build Tools>Gradle>Uncheck Offline work option in Android Studio
You can also invalidate Cache and Restart
