same error on Samsung devices

[fabiancrx]

Do you have any 'Steps to Reproduce' @darwin-morocho ? I can test with a samsung s8, would that device be representative of the issue?

[Wackymax]

Open a flutter app but don't open any of the sensor streams. Press the back button to close the app.

Thanks @darwin-morocho and @Wackymax, I'll take a look at this issue

[fabiancrx]

Actually it seems this issue should be solved after #838 is merged

It happens to most of the devices and the emulator as well using sensors_plus: 1.3.1 . Just when you close the app with the back button it occurs.

[Wackymax]

Any update on this? I see there is an open PR, when will it be merged and released?

[Medformatik]

My app also has this issue, so it would be great if the PR was merged as soon as possible.

[offline-first]

Please fix this bug
