Could not find com.google.firebase:firebase-crashlytics flutter

Question

I am not experienced in flutter but been doing it for a while. My current project is using firebase so I'm using flutterfire package and it has to be my worst nightmare so far. Build fail upon build fail. Note IOS is working though. The recent is this

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':firebase_crashlytics:compileDebugAidl'.
> Could not resolve all task dependencies for configuration ':firebase_crashlytics:debugCompileClasspath'.
   > Could not find com.google.firebase:firebase-crashlytics:.
     Required by:
         project :firebase_crashlytics

* 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.

* Get more help at https://help.gradle.org

Answer 1

You need to implement the dependencies in app-level gradle file app/build.gradle

// Add the Firebase Crashlytics SDK.
    implementation 'com.google.firebase:firebase-crashlytics:17.2.2'
    // Recommended: Add the Google Analytics SDK.
    implementation 'com.google.firebase:firebase-analytics:18.0.0'

The dependencies section should look like this

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:multidex:1.0.3'
    // Add the Firebase Crashlytics SDK.
    implementation 'com.google.firebase:firebase-crashlytics:17.2.2'
    // Recommended: Add the Google Analytics SDK.
    implementation 'com.google.firebase:firebase-analytics:18.0.0'
}

I hope this will fix your issue.

try changing the version in android/build.gradle:

    classpath 'com.google.gms:google-services:4.3.3'
    classpath 'com.google.firebase:firebase-crashlytics-gradle:2.2.0'

I hope I've helped

It is necessary to check the use of the setCrashlyticsCollectionEnabled, because if you disabled the crash collection setCrashlyticsCollectionEnabled(false) and then if later you want to enable it, just commenting out the above line DOES NOT automatically start the collection process if the app has already been installed with 'false' flag before, so setCrashlyticsCollectionEnabled(true) needs to be explicitly called again.

But for me the problem was exactly in setCrashlyticsCollectionEnabled(true), I called it every start, so I comment it out, and error disappeared.
