Trouble Migrating Android App to Flutter: Gradle Sync Fails After Firebase Integration

Help/Discuss
1

Hi everyone,
I’m migrating my Android Task Application (originally built with Java/Kotlin and SQLite) to Flutter using Dart. I’ve successfully set up most of the UI and integrated Firebase for real-time ads. However, after adding the Firebase dependencies, Gradle sync fails, and I can’t build the project.

Here’s what I’ve done so far:

  • Set up Firebase in the android/app with google-services.json
  • Updated build.gradle (both project and app level)
  • Added dependencies for Firebase and SQLite
  • Applied the necessary plugins

Errors I’m seeing:

[Insert specific error message here, e.g. "Could not resolve com.google.firebase:firebase-ads:xx.x.x"]

What I’ve tried:

  • Running flutter clean and flutter pub get
  • Checking internet connection and proxy settings
  • Making sure the google-services plugin version matches the Firebase BOM

I’d appreciate any suggestions or guidance on what to look into or how to resolve this. Thanks in advance!

Did you forget to share the error?
What you provided seems to be some template.
Optimally, share the build problem by sharing a build --scan URL.
