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:
