Class CodeScanner

startScanner

• startScanner(input?): Promise<string>

• Opens the camera and scans selected codes: (qr, aztec, dataMatrix, pdf417, code128 and ean13) A custom skin can also be provided to change the look of the scanner to one more appropriate to the code to be scanned.

  try {
      const modules = await Eitri.modules()

      const codeScannerModule = modules.codeScanner ?? modules.camera

      if (!startScannerMethod) {
          return // codeScanner module is unavailable, disable UI elements related to code scanning
      }
