Hi @wayupdev, I cannot reproduce this crash with demo app. Are you crashing the with demo app? If so, what are the steps to reproduce it?

[wayupdev]

Hi @aaassseee,

Sorry for the delay, on my side, I couldn't reproduce this crash on both app (demo and my own app). I only have the crashlytics report

@wayupdev how do you use the plugin? Just light up when go to one page,?

[wayupdev]

I use it in different way, in one part of my app, I have made a progressive brightness fonction like that :

double brightness = min(0.7, (info.currentTime.inSeconds / 5).floorToDouble() / 100); ScreenBrightness.instance.setApplicationScreenBrightness(brightness);

In some other part, I am just setting a value :

ScreenBrightness.instance.setApplicationScreenBrightness(0.1);

I also have a brightness.manager (where the issue seems to came from) :

import 'package:screen_brightness/screen_brightness.dart';

class BrightNessManager { static BrightNessManager manager = BrightNessManager(); late double brightness;

Future init() async { brightness = await ScreenBrightness.instance.application; } }

@wayupdev Will it be possible when progressive brightness changing when user quit the application?

[wayupdev]

Yes, I think the user puts the application in background and the package tries to modify the brightness without success, causing the crash.

[aaassseee]

@wayupdev pausing the application should not cause this issue. Can you repeat this issue on your side?

[wayupdev]

I'll try to reproduce it, and I'll keep you posted. Thanks for your help

[aaassseee]

Sure. If it crash on pause, this is a critical issue.
