3 years ago I realized this log above is with catcher handling exceptions. Here is another one without it, but it doesn't look more useful.

3 years ago Hi. Here is minimum reproducible example.
Please note that null-safety must be enabled in with sdk version in pubspec.yaml, otherwise the issue does not occur.
environment:
sdk: '>=2.12.0 <3.0.0'It throws at array_patch.dart:40, before reaching home widget. Running on Android Emulator qemu-system-x86_64 and on LG H850.
import 'package:flutter/material.dart';
import 'package:catcher/catcher.dart';
void setupCatcher(Widget child) {
Catcher(
rootWidget: child,
ensureInitialized: true,
);
}
void main() {
setupCatcher(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: Scaffold(
body: Center(
child: Text('Flutter Demo Home Page'),
),
),
);
}
}It seems like a problem of device_info_plus, doesn't it?

On LG H850 app crashes before reaching home screen due to device_info crashing due to missing systemFeatures tag. Since this is hardware specific, its probably hard to reproduce it with different hardware. It looks like an easy null check fix so I hope you can take some action based on this report.
