Hi, I have some weird crash on Android.
I initially tested on my Flutter app, then I tested on the default example Flutter app .
This is the output is the same for both apps.

When I launch the app:

E/flutter (11976): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: Null check operator used on a null value
E/flutter (11976): #0      MethodChannel.binaryMessenger (package:flutter/src/services/platform_channel.dart:121:86)

Side notes
I am registered on AppSpector.
I created two projects (iOS and Android) in it.
My Flutter version: 2.5.1
My Dart SDK version: 2.14.2

I followed the instructions that I found on pub.dev for your plugin so:

  • added the dependency on pubspec.yaml
  appspector: '0.8.1'
  • initialized the plugin in main.dart
  runAppSpector();
  runApp(const MyApp());
}

void runAppSpector() {
  final config = Config()
    ..iosApiKey = "my API key for ios"
    ..androidApiKey = "my API key for android ";
  
  config.monitors = [Monitors.http, Monitors.logs, Monitors.screenshot];

  AppSpectorPlugin.run(config);
}

Can you help?
Thanks a lot!

Thanks for report. We will take a look at this wired behavior

Hey @matteoKuama, sorry for the delay! I've completely forgotten to answer.
It seems you have not put the WidgetsFlutterBinding.ensureInitialized(); line before initializing the plugin.
