[Bug]: Stream emitting same values after app being in background on device Xiaomi Mi MIX 2 (Android)

Open sentd94 opened this issue 3 years ago • 0 comments

Platform

Android 9

Plugin

sensors_plus

Version

1.3.4+1

Flutter SDK

Steps to reproduce

Note: I could not reproduce this on an Emulator device. I also don't have another physical device here to test this. So this might be a MIUI specific issue.

Put the app in background (on Android press the Home Button).
Unfortunately you have to wait now for a couple of minutes to reproduce (I waited for 6 minutes, might be possible sooner).
Now put the app in front again. The stream is going to emit the same values over and over no matter what.

Code Sample

import 'package:flutter/material.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'dart:math';
import 'package:sensors_plus/sensors_plus.dart';

final speedProvider = StreamProvider<double>((ref) {
  return userAccelerometerEvents.map((event) =>
      sqrt(event.x * event.x + event.y * event.y + event.z * event.z));
});

class FrontPageWidget extends ConsumerWidget {
  const FrontPageWidget({Key? key}) : super(key: key);
  static const routeName = '/frontPage';

  @override
  Widget build(BuildContext context, WidgetRef ref) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Main Page'),
      ),
      body: Text(ref.watch(speedProvider).value.toString()),
    );
  }
}
