Managing State Tutorial Crashes Galaxy s6 #362
Description
I tried running the Managing State Tutorial on my Galaxy S6 Edge and I can use the app for a few seconds and then it will either show a black screen or a red screen. It will crash whether I use the button to increment the counter or not, but it will increment.
Here is the code I am running:
import 'package:flutter/material.dart';
void main() {
runApp(
new MaterialApp(
title: 'Flutter Leads',
routes: {
'/': (RouteArguments args) => new Counter()
}
)
);
}
class Counter extends StatefulComponent {
_CounterState createState() => new _CounterState();
}
class _CounterState extends State<Counter> {
int _count = 0;
void _increment() {
setState(() { ++_count; });
}
Widget build(BuildContext context) {
return new Row([
new RaisedButton(
onPressed: _increment,
child: new Text('Increment')
),
new Text('Count: $_count')
]);
}
}
This is the error I got:

Thanks for the report. That's very strange. We'll need to try replicating the issue on our end.

I removed the RaisedButton and changed Text to just plain text, it seems to sit there and doesn't crash, but if you tap the screen it will do some sort of fade down animation, and then the screen is black. I am having a hard time recreating the red screen.

A ton of code has changed here. Going to close with the hopes that it's working for you. If not, we'll reopen and take a look.
Thanks for the report! Please give it a shot again and let us know.
