The bar code is missing and cannot be identified completely

Hello I'm glad to find your open source project However, during the testing process, The bar code is missing and cannot be identified completely

Not sure what exactly is the problem? Is barcode missing or is it not identified completely? These are two distinct cases. If you're missing part of the barcode have you tried to specify bufferDuration parameter to something longer, IE. 500 ms?

Have you tried modifing bufferDuration parameter?

const Duration aSecond = Duration(seconds: 1); const Duration hundredMs = Duration(milliseconds: 500); const int lineFeed = 10;

我改了hundredMs=500 但是测试结果，还是一样。 数字还是出现缺失

Thank you very much. After testing, change RawKeyUpEvent to RawKeyDownEvent It can be correctly identified

[zouxianbincc]

void _keyBoardCallback(RawKeyEvent keyEvent) { if (keyEvent.logicalKey.keyId > 255 && keyEvent.data.logicalKey != LogicalKeyboardKey.enter) return; if (keyEvent is RawKeyDownEvent) { if (keyEvent.data != null) { if (keyEvent.data is RawKeyEventDataAndroid) { _controller.sink.add(((keyEvent.data) as RawKeyEventDataAndroid).codePoint); } else if (keyEvent.data is RawKeyEventDataFuchsia) { _controller.sink .add(((keyEvent.data) as RawKeyEventDataFuchsia).codePoint); } else if (keyEvent.data.logicalKey == LogicalKeyboardKey.enter) { _controller.sink.add(lineFeed); } } else { _controller.sink.add(keyEvent.logicalKey.keyId); } } }

Glad it worked. If you check history you'll see I started with KeyDown but moved to KeyUp because there were some issues. Don't remember why anymore.
