Notice

What does it do?#

Crashlytics helps you to collect analytics and details about crashes and errors that occur in your app. It does this through three aspects:

  • Logs: Log events in your app to be sent with the crash report for context if your app crashes.
  • Crash reports: Every crash is automatically turned into a crash report and sent when the application next opens.
  • Stack traces: Even when an error is caught and your app recovers, the Dart stack trace can still be sent.

Installation#

1. Add dependency#

On the root of your Flutter project, run the following command to install the plugin:

flutter pub add firebase_crashlytics

2. (optional) Platform integration for Android#

Dart-only Firebase initialization for Android currently only supports reporting Dart exceptions. To report native Android exceptions, please follow the steps below.

  1. Add the following classpath to your android/build.gradle file.
android/build.gradle
dependencies {
// ... other dependencies such as 'com.google.gms:google-services'
classpath 'com.google.firebase:firebase-crashlytics-gradle:2.7.1'
}
  1. Apply the following to your android/app/build.gradle file.
android/app/build.gradle
// ... other imports
android {
// ... your android config
}
dependencies {
// ... your dependencies
}
// This must appear at the bottom of the file
apply plugin: 'com.google.firebase.crashlytics'

3. Rebuild your app#

Once complete, rebuild your Flutter application:

flutter run

Next steps#

Once installed, you're ready to start using Firebase Crashlytics in your Flutter Project. View the Usage documentation to get started.
