[Bug]: gyroscope/accelerometer "channel sent a message from native to Flutter on a non-platform thread" #2315
Comments
|
Here are a number of issues recently reported that appear to be related. Debugging -my- problem shows this to be pretty far down the stack and not in application code. Adding the recommended dispatch_asynch around all "eventSink{" calls results in 26 Dart appendages 12 js appendages. So, my question: are these issues related? Many people seem to be hitting it based on the comments. I really don't think this issue is at the application development layer, but I can always be educated if it is. TIA. firebase/flutterfire#11667 |

Plugin
sensors_plus
Version
3.1.0

Steps to reproduce
The call to DeviceSensors() below to instantiate accelSub and gyroSub throws the channel error in the title.
"[VERBOSE-2:shell.cc(1004)] The 'dev.fluttercommunity.plus/sensors/accelerometer' channel sent a message from native to Flutter on a non-platform thread. Platform channel messages must be sent on the platform thread. Failure to do so may result in data loss or crashes, and must be fixed in the plugin or application code creating that channel."
"[VERBOSE-2:shell.cc(1004)] The 'dev.fluttercommunity.plus/sensors/gyroscope' channel sent a message from native to Flutter on a non-platform thread. Platform channel messages must be sent on the platform thread. Failure to do so may result in data loss or crashes, and must be fixed in the plugin or application code creating that channel."
accelSub = accelerometerEvents.listen(processAccel);
gyroSub = gyroscopeEvents.listen(processGyro);
