如何让 Android 和 iOS 的 Flutter App 崩溃（测试 Firebase Crashlytics）？

Question

I want to test out crash report using Firebase Crashlytics in my Flutter App. I need to Fatal crash my flutter app for both Android and iOS programmatically. Any idea?

Answer 1

You should be able to throw a Dart exception by doing this anywhere in your Flutter app:

throw Exception("This is a crash!");

Or by using an arbitrary object:

throw "This is a crash!";

You can find more info about dart exceptions in the language tour and if you want, you can create your own custom Exception type as explained in this SO answer

Answer 2

如果你有flutter_crashlytics插件，你可以使用

FirebaseCrashlytics.instance.crash();

Answer 3

集成firebase_crashlytics

 Crashlytics.instance.crash();

Answer 4

using firebase_crashlytics plugin

FirebaseCrashlytics.instance.crash();

You should enable crashlytics

void main() async{
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  if (kDebugMode) {
    FirebaseCrashlytics.instance.setCrashlyticsCollectionEnabled(true);//disable false
  }else{
    FirebaseCrashlytics.instance.setCrashlyticsCollectionEnabled(true);
  }

Answer 5

Divide by zero. Parse wrong data wrong way (ie float string as int). Throw uncaught exception. Access things you got no permissions for. And so on. Be creative

Answer 6

Try to add any value without initializing the list. there will be an app crash and give this error The method 'add' was called on null.

List list;

list.add("add");

Answer 7

You can crash you Flutter app by many ways:

1. throw(Exception('Hello Crashlytics')); like in @Xavi Rigau's answer

List list;

list.add("add");

Like @Paresh Mangukiya does.

3.

final a = [12];
print(a[1]);

But there is 2 IMPORTANT thing you should consider:

• You should run your app in release mode, for example with the command flutter run --release
• In Crashlytycs console, by default shown only fatal crashes. The crashes above are non-fatal crashes. So, you should clear the filter to see all crash types. (Filter can be filtered in crashlytics dashboard by clicking (x) button near filter). More on this you can read from this SO answer

Answer 8

Check this out . This is from the official documentation. https://firebase.flutter.dev/docs/crashlytics/usage

Once your configuration is proper according to documentation for crashlytics, FirebaseCrashlytics.instance.crash(); will crash the app.
