Flutter：如何使用Flutter获取扫描条形码的格式？

Question

[我正在尝试构建一个条形码扫描仪应用程序，该摄像头使用相机扫描条形码，我设法将一些条形码插件摆弄得井井有条，但它们似乎都以字符串形式返回结果，并且没有插件也可以检测条形码的格式，是否有解决方法？

更新：pubspec.yaml

对于面临相同问题的任何人，我都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，而是添加了扫描代码的类型：

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
    }
