Firebase Crashlytics

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.

Usage in Flutter

import 'package:flutter/foundation.dart' show kDebugMode;
// …
if (kDebugMode) {
   // Force disable Crashlytics collection while doing every day development.
   // Temporarily toggle this to true if you want to test crash reporting in your app.
   await FirebaseCrashlytics.instance
       .setCrashlyticsCollectionEnabled(false);
 } else {
   // Handle Crashlytics enabled status when not in Debug,
   // e.g. allow your users to opt-in to crash reporting.
 }

if (FirebaseCrashlytics.instance.isCrashlyticsCollectionEnabled) {  
// Collection is enabled.
} 
FirebaseCrashlytics.instance.crash();
