i get that error , how to fix it ?

[axroromonov44]

The 'com.dynamsoft/barcode_result_observer' 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. See https://docs.flutter.dev/platform-integration/platform-channels#channels-and-platform-threading for more information.

Hi @axroromonov

We fixed this issue in the v1.2.3 branch but it is still not released. For some reason, we can't confirm the release date of the 1.2.3 version currently. I think the change logs of v1.2.3 branch might help you debug this issue.

and I have a question in terms of performance , the device gets very hot when the camera is opened on iOS , how to normal it ?

[Dynamsoft-Henry]

Hi @axroromonov. That's because of the high occupancy of the CPU. The library will continuously process the video frames after you startScanning. If you don't stopScanning, the device does get hot.

We have an API to control the barcode decoding interval, which might work for you. The API is currently not added to the Flutter platform. Please let me know if you want to try the API. We can add it.

However, I think the best solution is to stopScanning when you don't want to process the video frames.

thank you for response , I will read the data-matrix through your packages, it may take a long time, for example, I may have to read 100-200 matrices at the same time, at this time my phone will be as hot as the sun, I like this package but it is a bit difficult in terms of performance

Error (Xcode): Building for 'iOS-simulator', but linking in dylib (/Users/it-admin/Documents/git_lab/agrokomak_mobile/ios/Pods/DynamsoftBarcodeReader/DynamsoftBarcodeReader.framework/DynamsoftBarcodeReader) built for 'iOS'

Could not build the application for the simulator. Error launching application on iPad Pro (11-inch) (4th generation).

When I try to run it on iPad, I have such a problem, how can I fix it?

[Dynamsoft-Henry]

Hi @axroromonov

We updated the 1.2.3 branch to support the simulator.

For the iPad issue, we might need some more time.

[axroromonov44]

this is the same problem in the simulator as well as in the real iPad

[Dynamsoft-Henry]

Hi @axroromonov We tested our changes on the iPad and it is working fine now. We uploaded the changes in the 1.2.3 branch, would you like to have a look at it?

[axroromonov44]

Yes, I'm a little confused, it worked, but it doesn't work in the simulator

[axroromonov44]

What are the changes in this version? in 1.2.3

[axroromonov44]

I still see version 1.2.2

[Dynamsoft-Henry]

If you are still in 1.2.2, please remove your workspace, pods folder and pod lock file (all the files created by pod install).

Run the pod update, and then run pod install.

We added the support of the architectures that are required by simulators.

[axroromonov44]

pub.dev still has 1.2.2, you can check it

[axroromonov44]

[Dynamsoft-Henry]

We didn't talk about the pub.dev. We updated the changes on GitHub 1.2.3 branch. Currently, the formal release of the 1.2.3 version is still not arranged.

[axroromonov44]

sorry ,I thought it was on pub.dev . Cool , I will try it . Do you have any communities ?

[Dynamsoft-Henry]

Do you mean a community edition? Sorry, we don't.

[axroromonov44]

ok got it , good luck !
