android - flutter : How to get the format of the scanned barcode using flutter?

Question

我正在尝试构建一个条形码扫描仪应用程序，它使用相机扫描条形码，我设法在 flutter 中使用一些条形码插件，但它们似乎都以字符串形式返回结果，但没有一个也检测条形码格式的插件，有没有办法解决这个问题？

对于面临同样问题的任何人，我可以通过更改该库提供的 kotlin 代码来解决此问题，而不是返回条形码/二维码编号，而是添加扫描代码的类型:

private fun createBarCodeView(): BarcodeView? {
 val barcode = BarcodeView(registrar.activity())
 barcode.decodeContinuous(
 object : BarcodeCallback {
    override fun barcodeResult(result: BarcodeResult) {
      var output = result.text + "____"+result?.barcodeFormat.toString() // <== this did the trick
  channel.invokeMethod("onRecognizeQR", output)
                    }
  override fun possibleResultPoints(resultPoints: List<ResultPoint>) {}
                }
        )
        return barcode
    }
