On flutter only it works, on ios + flutter also works, but in android i get this messages.

Also:

E/flutter: [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Null check operator used on a null value

0 FlutterUxcam.startWithConfiguration (package:flutter_uxcam/flutter_uxcam.dart:75:18)

ON FlutterUxcamPlugin.java line 306, avtivity is null.

UXCam.startWithConfigurationCrossPlatform(activity, config);

Hey @CarlosAMS123 Diego here from UXCam.

Can you share the following information:

• Which UXCam version you are currently using?
• Additionally, I can see that you are already receiving sessions and have two applications - is the previous crash that you reported for your staging or production application?
• Can you also share a snippet of the code on how you are implementing UXCam in your application?

[ghost]

Of course @DFDIEGOH :

• UXCam flutter verson: flutter_uxcam: ^2.2.2
• It's for stagin application. We are currently switching to flutter inside android native, there were we having the issue.
• Snippet:

class MyApp extends StatelessWidget { const MyApp({super.key});

/// This widget is the root of your application. @override Widget build(BuildContext context) { initUxcam(); return MaterialApp.router( routerConfig: router, title: 'Flutter Demo', localizationsDelegates: AppLocalizations.localizationsDelegates, supportedLocales: const [ /// Spanish (Disabled for english) Locale('es'), ], theme: BaseAppTheme.lightTheme, ); }

void initUxcam() { FlutterUxcam.optIntoSchematicRecordings(); FlutterUxConfig config = FlutterUxConfig( userAppKey: 'XXXXXXXXXX', enableAutomaticScreenNameTagging: false, ); FlutterUxcam.startWithConfiguration(config); } }

@DFDIEGOH hi, it's the any update about the problem?

[DFDIEGOH]

Hey @CarlosAMS123 I'm currently checking this with the team, let me get back to you shortly.

[DFDIEGOH]

In the meantime, are you using any other UXCam methods in your application? or is this happening just with the startWithConfiguration method at the moment of initializing the SDK?

[ghost]

@DFDIEGOH thanks for the time! No, uxcam it's only used there.

[DFDIEGOH]

Hi @CarlosAMS123 Quick question in here - you mentioned that you are switching to Flutter inside Android native. Is it that you have a Android native application with Flutter modules inside? Or can you share more context in this scenario as well? Perhaps a call to understand more about this scenario will also be very helpful

[ghost]

@DFDIEGOH Thats correct, there it's only 1 flutter module, and there it's where we are using uxcam. I think a call would be perfect to show you our arch, can we schedule a meeting?

[DFDIEGOH]

Understand now the problem @CarlosAMS123 - As UXCam needs to start recording as soon as the application is starting (in other words, from your launcher activity) this is creating some problems in this regard. I'm currently checking this with the team on different possibilities but definitely having a call to understand more about this will definitely help. Here you can find my calendar with my availability.

Looking forward to speak with you

[ghost]

@DFDIEGOH thanks! Already shcedule for tomorrow, have a nice day.

[DFDIEGOH]

Quick question @CarlosAMS123 - I've checked that a call has been schedule tomorrow but at 11:15am Central European Time, is this correct? Just want to make sure that you have the correct timezone as well

[ghost]

@DFDIEGOH it's correct! Thank you

[ghost]

@DFDIEGOH sorry! You were right. I don't consider the 24hr clock and thought it was 4 PM. Can we reschedule?

So sorry for the inconveniences!

[DFDIEGOH]

Hey @CarlosAMS123 Sure, No worries at all, we can reschedule - We are currently working in the CET Timezone, you can again check using the link that I shared with you before and pick the best time slot for you

[ghost]

@DFDIEGOH Thanks! i already reschedule, see you tomorrow!

[DFDIEGOH]

This should be fixed in the latest version of the Flutter_UXCam package, version 2.4.6
