# Firebase Crashlytics Skill This skill defines how to correctly use Firebase Crashlytics in Flutter applications. ## When to Use Use this skill when: * Implementing crash reporting in a Flutter project. * Capturing fatal errors, non-fatal exceptions, and async/isolate errors. * Customizing crash reports with keys, logs, and user identifiers. * Configuring opt-in data collection or disabling reporting in debug builds. * Uploading symbol files for obfuscated builds. --- ## 1. Setup and Configuration ``` flutter pub add firebase_crashlytics flutter pub add firebase_analytics # enables breadcrumb logs for better crash context ``` Run `flutterfire configure` to update the Firebase configuration and add the required Crashlytics Gradle plugin for Android. ```dart import 'package:firebase_crashlytics/firebase_crashlytics.dart'; ``` **Obfuscated code:** - For apps built with `--split-debug-info` and/or `--obfuscate`, upload symbol files for readable stack traces. - **iOS:** Flutter 3.12.0+ and Crashlytics Flutter plugin 3.3.4+ handle symbol upload automatically. - **Android:** Use Firebase CLI (v11.9.0+) to upload Flutter debug symbols: ```bash firebase crashlytics:symbols:upload --app=FIR

Use when implementing crash reporting, capturing fatal/non-fatal errors, recording isolate/async exceptions, customizing reports, or uploading obfuscated symbols.
How do I install it?

Where does this skill come from?
From evanca/flutter-ai-rules, a repository with 604 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
