Did this start with an update or did you see this also with older versions?
zoechi

@zoechi I saw this on both the previous and the current version.
I can see this also when launching browser within the application.
launch("url");
is this due to a memory shortage?
I'm using 4 gif animations on my widget.

Animated gifs rings a bell
I found https://github.com/flutter/flutter/issues/9707#issuecomment-421735556
Uh, this what was I remembered seeing https://github.com/flutter/flutter/issues/20998#issuecomment-420101036
but that is about iOS

Yes, on Windows, Lost connection to device appears on full-restart (using the green play button in Android Studio). I have also noticed that it does not happen with hot-reloads on saving the files.

May be helpful to mention that the animations are around a total of 7 MB of size.

@zoechi I released and tested the app on 2 samsung devices, and it is not crashing,
this is only crashing, on emulator and on windows.
p30arena
on 26 Sep 2018
@zoechi
Tested on older devices with lower memories,
The app crashes out of blue.
p30arena
on 26 Sep 2018
@zoechi
My Conclusion: 7 MB of gif animations take about more than 1 GB of memory in flutter.
So the OS kills the app on low memory conditions.

I'm experiencing the same issue. The app worked fine on the emulator initially, however, when I updated flutter, I'm getting the 'lost connection to device' error. Flutter doctor says no issues found!

I have same problem. Then i switched to another emulator works again but then I do a full restart get same issue.

Happening for me as well with version 1.5.4-hotfix.2, both in VS Code and just flutter run. Happens consistently every time at the moment, so cannot debug my app 😬

Could everyone who still has this problem please file a new issue with the exact descriptions what happens, logs and the output of 'flutter doctor -v' please.
All system setups can be slightly different so it's always better to open new issues and reference related issues.

Hi!
The app crashes from time to time, after a dozen updates to the code, but I haven't experienced this issue recently.

I had the same problem. Then I upgrade the flutter version with 'flutter upgrade' and it works for me. If you still don't know how to solve it, you can try this out. Hope it helps you.

Yes, on Windows,
Lost connection to deviceappears on full-restart (using the green play button in Android Studio). I have also noticed that it does not happen with hot-reloads on saving the files.
i have this error form 2 months i was able to use the hot reload mode i solved this issue is now solved by me just change our mobile charging cable and use usb cable.

My Conclusion: 7 MB of gif animations take about more than 1 GB of memory in flutter.
So the OS kills the app on low memory conditions.
