Solution : Local module descriptor class for com.google.android.gms .providerinstaller.dynamite not found : Flutter Firebase

If you are a Flutter developer using Firebase in your application, you may have encountered the error message “Local module descriptor class for com.google.android.gms .providerinstaller.dynamite not found” at some point during your development. This error often occurs when you are trying to integrate Firebase services into your Flutter app using the firebase_core and firebase_auth packages. In this blog post, we will dive deeper into the possible causes of this error and explore ways to fix it.

What is the “Local module descriptor class for com.google.android.gms .providerinstaller.dynamite not found” error?

The error message “Local module descriptor class for com.google.android.gms .providerinstaller.dynamite not found” is related to the Google Play services library used by Firebase in Android applications. Firebase relies on the Google Play services library to provide various functionalities such as authentication, cloud messaging, real-time database, and more.

When you integrate Firebase into your Flutter app, the firebase_core and firebase_auth packages try to access a specific class named com.google.android .gms.providerinstaller .dynamite.ModuleDescriptor from the Google Play services library. However, in some cases, this class is not found, leading to the occurrence of the error.

What causes the “Local module descriptor class for com.google.android.gms .providerinstaller.dynamite not found” error?

There can be several reasons behind the “Local module descriptor class for com.google.android.gms .providerinstaller.dynamite not found” error. Let’s explore some common causes:

1. Outdated Google Play services version:

The most common reason for this error is an outdated version of the Google Play services library. When you use the Firebase packages, they require a specific version of the Google Play services library. If your current version is outdated or doesn’t match the required version, the ModuleDescriptor class may not be found, causing the error.

2. Conflict with other dependencies:

In some cases, the error may be caused by conflicts between different dependencies in your Flutter app. These conflicts can lead to issues in resolving the correct version of the Google Play services library, resulting in the “Local module descriptor class for com.google.android.gms .providerinstaller.dynamite not found” error.

3. Incompatible Firebase package versions:

Using incompatible versions of the Firebase packages can also trigger this error. When you use Firebase in your app, it’s essential to ensure that all Firebase-related packages are compatible and have the same version. Mismatched versions can cause issues with the required classes and result in the error.

How to fix the “Local module descriptor class for com.google.android.gms .providerinstaller.dynamite not found” error?

Now that we understand the possible causes of the error, let’s explore some solutions to fix it:

1. Update Google Play services library:

The first and most crucial step is to ensure that you have the correct version of the Google Play services library. Open your Android project’s build.gradle file and check the version of com.google.android.gms:play-services and com.google.firebase:firebase-bom dependencies. Make sure they match the required versions specified in the Firebase documentation.

<dependencies>
    // Other dependencies...

    implementation 'com.google.android.gms:play-services:{{VERSION}}'
    implementation platform('com.google.firebase:firebase-bom:{{VERSION}}')
</dependencies>

2. Resolve dependency conflicts:

If you encounter conflicts between different dependencies in your app, you can use the dependency_overrides section in your Flutter project’s pubspec.yaml file to force a specific version of the Google Play services library. This can help ensure that the correct version is used and resolve the error.

dependency_overrides:
  com.google.android.gms:play-services: {{VERSION}}
  com.google.firebase:firebase-bom: {{VERSION}}

3. Update Firebase packages:

Make sure all Firebase-related packages in your pubspec.yaml file have the same version. Use the latest versions of the packages to ensure compatibility and prevent any conflicts. You can find the latest versions of Firebase packages on the official FlutterFire GitHub repository.

dependencies:
  flutter:
    sdk: flutter
  firebase_core: {{VERSION}}
  firebase_auth: {{VERSION}}
  // Other Firebase packages...
