how to use `crashlytics` in firebase in 3 Steps

Step 1: Create your Firebase Project in the Firebase console and enable crashlytics

Firebase console: https://console.firebase.google.com

Step 2: Install these 2 packages in our pubspec.yaml

Then let's go to main.dart and initialize FireBase

and add these 2 lines

.
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
.

Step 3: initialize Firebase Crashlytics

so let's add this line to main()

.
FlutterError.onError = FirebaseCrashlytics.instance.recordFlutterFatalError;

.

That is for overriding FlutterError.onError with FirebaseCrashlytics.instance.recordFlutterError

which will automatically catch all errors that are thrown within the Flutter framework. and sent it to the Firebase dashboard

All Done!!

We don't have to wait for a crash

Let's Force a test crash to check if working or not!!

so let's add this line to a button or in the initState

.
FirebaseCrashlytics.instance.crash();

.

Stop and re-Run your app again, And wait 10 mins till the first data reach the Crashlytics dashboard of the Firebase console.

and as you see in the dash we are receiving crash errors
