Intro to the Topic : Firebase Crashlytics 🚀

Firebase Crashlytics — Firebase Crashlytics is a lightweight, realtime crash reporter that helps you track, prioritize, and fix stability issues that erode your app quality.

The Most Powerful, yet Lightest Weight Crash Reporting Solution

Crashlytics helps using 3 main aspects :

Logs: Each events in app is logged so that conext can be provided alongwith crash reports on the event of app crash

Crash reports: Crash reports is made up each time a crash occurs and sent up on the application being run the next time .

Stack traces: If the app recovers from an error , Dart Stack trace help in still Reporting the error.

Implementation Pattern : Firebase Crashlytics

Let us understand the Implementation pattern of Firebase Crashlytics:-

Firebase Crashlytics saves you troubleshooting time by Intelligently Grouping Crashes and Highlighting the circumstances that lead up to them.

: Connect Your App — Add On Firebase To Your Apps.

Integrate The SDK — Add the Crashlytics SDK

: Check Firebase Console — Visit the Firebase console to track, prioritize, and fix issues in your app.

Firebase Crashlytics — Setup & Initial Configuration

In order to Integrate Crashlytics, We need to create a firebase project for the Firebase Crashlytics from firebase.google.com by logging in with your Google account. This brings us to the following screen:

Add project at Firebase Console

Click on Add Project Button (+) initiating firebase project creation process.

Mention Name of project

Select the appropriate name for the project entering continue further

select analytics (if needed )

You can either select the firebase analytics and then clicking on Continue Project. Firebase Project is now created and ready to use .

Firebase project created

This Progress indicator will show before the dashboard indicating success.

Dashboard Screen

In the project overview page, click the iOS icon to launch the setup workflow as we now needs to register your flutter project for the android and iOS application.

Integration with iOS App

In the project overview page, select the iOS icon to launch the setup flow. If you have already added the app to your project provide click on add app to provide details of your application.

iOS app Integration
  1. Register your app with Firebase :
  2. a. Provide with your app’s bundle ID.
    Find this bundle ID from your open project in XCode. Select the top-level app in the project navigator, then access the General tab. The Bundle Identifier value is the iOS bundle ID (for example, com.yourcompany.ios-app-name).
    b. You may also provide optional details like App Nick Name and App Store ID.
    c. Register your app.

Make sure you enter the correct ID As this can’t be edited further at the moment .

Download GoogleService-Info.plist

Next step, We need to download the config file named GoogleService-info.plist & repeating a similar process to registering your android app there saving the Google-service.json file. Keep those configuration files in ready-to-use with the Flutter app later.

google-service.json

Open Project Settings in the Firebase console and select iOS application.

Now We need to add the App Store Id of the flutter application which can be located at the app’s URL.

We can also use makeshift app ID if our app is not published yet which can be replaced later.

We may need to add the Team ID which can be located at the Apple Member Centre under the provisioning profile.

Add the Firebase configuration file :

:. Click Download GoogleService-Info.plist to obtain your Firebase iOS config file (GoogleService-Info.plist).

Make sure the config file is not appended with additional characters, like (2).

:. Using XCode, move the file into the Runner/Runner directory of your Flutter app.

Adding Crashlytics plugin In Flutter App :

Add Package Dependency in pubspec.yamland the run Flutter pub get :

firebase_crashlytics: "^0.2.0"

Add the following classpath to your android/build.gradle file :

dependencies {
classpath 'com.google.firebase:firebase-crashlytics-gradle:2.2.0'}

Apply the following Plugin to the end of your android/app/build.gradle file.

apply plugin: 'com.google.firebase.crashlytics'

Add the Firebase Crashlytics SDK, in your android/app/build.gradle files.

dependencies {
// Adding Firebase Crashlytics SDK
implementation 'com.google.firebase:firebase-crashlytics:17.0.0-beta01'
}

iOS :

: Select Runner at project navigation from Xcode .

: Then Select the Tab Build phase => Click on + > New Run Script Phase

: Add ${PODS_ROOT}/FirebaseCrashlytics/run to the Type a script.. text box.

Import package At Your Project File:

import 'package:firebase_crashlytics/firebase_crashlytics.dart';

Add Firebase Crashlytics Instance In Your Flutter App :

void main() {
// Set `enableInDevMode`to true to see reports while in debug mode
// This is only to be used for confirming that reports are being
// submitted as expected. It is not intended to be used for //everyday development.
Crashlytics.instance.enableInDevMode = true;

// Pass all uncaught errors to Crashlytics.
FlutterError.onError = Crashlytics.instance.recordFlutterError;
WidgetsFlutterBinding.ensureInitialized();
SystemChrome.setEnabledSystemUIOverlays([SystemUiOverlay.bottom]).then((_) {
SharedPreferences.getInstance().then((prefs) {
var darkModeOn = prefs.getBool('darkMode') ?? true;
runZoned(() {
runApp(ChangeNotifierProvider<ThemeNotifier>(
create: (_) => ThemeNotifier(darkModeOn ? darkTheme : lightTheme),
child: MyApp(),
));
}, onError: Crashlytics.instance.recordError);
});
});
}

Rebuild your app :

$ flutter run

You will be abled to see the crashlytics dashboard in firebase console on successful installation

Crashlytics Console
