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.


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.
dependencies {
// ... other dependencies such as ''
classpath ''
  1. Apply the following to your android/app/build.gradle file.
// ... other imports
android {
// ... your android config
dependencies {
// ... your dependencies
// This must appear at the bottom of the file
apply plugin: ''

3. Rebuild your app#

Once complete, rebuild your Flutter application:

flutter run
