barcode initialization error

kamarul-ariffin-github commented 1 month ago

i already follow your advice on previous issue. now i got this error when i want to initialize the barcode scanner: 10-31 22:08:53.407 15383 15413 E ReactNativeJS: 'Error in barcode initialization', [TypeError: undefined is not a function]

here is my code where this error occur:

if (!isInitialized) {
        if (typeof RNChainwaySensors.initializeBarcodeReader !== "function") {
          console.error("initializeBarcodeReader is not a function");
          return;
        }
        let result = await RNChainwaySensors.initializeBarcodeReader();
        console.log("initialize barcode reader result: ", result);
      }
    } catch (error) {
      console.error("Error in barcode initialization", error);
      console.error("Error details:", {
        name: error.name,
        message: error.message,
        stack: error.stack,
      });

Ok man, found a misspelled function. Just update the package, i've released a new version.

thanks!

Let me know if is all working!

I have done some testing but still not working for the barcode. it is sucessfully initialized:

11-01 09:34:38.173 24276 24306 I ReactNativeJS: 'Is barcode reader initialized:', false
11-01 09:34:39.310 24276 24306 I ReactNativeJS: 'initialize barcode reader result: ', true

but the startbarcode scan is not returning any data:

const startScan = async () => {
    console.log("start scan before");
    try {
      let result = await RNChainwaySensors.startBarcodeScan();
      console.log("start barcode scan result: ", result);
    } catch (error) {
      console.error("Error", error);
    }
    console.log("start scan after");
  };

  const stopScan = async () => {
    console.log("stop scan before");
    try {
      let result = await RNChainwaySensors.stopBarcodeScan();
      console.log("stop barcode scan result: ", result);
    } catch (error) {
      console.error("Error", error);
    }
    console.log("stop scan after");
  };

check the addBarcodeListener function in the library. When barcode is read, throws a 'BARCODE' event.

do something like this:

    const handleBarcodeScan = (args: any) => {
      const data = args;
     console.log("Barcode data",data)
    };

    RNChainwaySensors.addBarcodeListener(handleBarcodeScan);
