Flutter-pi compiled app on CoreMP183 errors #437

When I run it 

root@CoreMP135:~# flutter-pi --release ./boatinstrument
[locales] Warning: The system has no configured locale. The default "C" locale may or may not be supported by the app.
WARNING: Detected llvmpipe (ie. software rendering) as the OpenGL ES renderer.

         later on in the initialization.

Sorry for the delay. That's probably a bug. The hardware mouse cursor is not really well-supported, it's only a help for debugging, if you don't have a touchscreen.

Maybe this helps for now: https://gist.github.com/ardera/e7ddf7c8e477d258a26dfa9c40002626 (though you'll still get the error messages)

I'll keep this issue open until I fix it.

I have touchscreen with USB interface and no mouse

Errors occur when I move a finger over the touchscreen

Thanks

Is your touchscreen controller an AR1100 by any chance?

My touchscreen:

[  492.416884] input: WingCool Inc. TouchScreen Touchscreen as /devices/platform/soc/5800d000.usbh-ehci/usb2/2-1/2-1.4/2-1.4.2/2-1.4.2:1.0/0003:27C0:0818.000D/input/input13

There seems to be some timeouts in Flutter GestureDetector with touch:

There are also these:

libinput error: event2  - WingCool Inc. TouchScreen Mouse: client bug: event processing lagging behind by 629ms, your system is too slow
libinput error: event2  - WingCool Inc. TouchScreen Mouse: client bug: event processing lagging behind by 890ms, your system is too slow
