Converting a ByteData variable to BitMap?

1

Does anyone know how to solve this error when converting a ByteData variable to BitMap?

I am building a Flutter Application, and there is one part in my code that I need to use an Android API (written in Kotlin). Specifically, I’m using a Platform Channel to pass an Image as an argument in a method in the Kotlin file. Based on this site, I figured out that I need to get the ByteData from the image File and send them as a parameter to the function, where the Kotlin code will convert them to BitMap. However, where I get the following error:

E/flutter (14160): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: Invalid argument: TypedDataView(cid: 142)

Does anyone know how to solve this?

Code in Dart:

Future readTextKotlin() **async** {
**for** (int countReceiptImages = 0; countReceiptImages < **listProducts** . **length** ; countReceiptImages++) {

File file = File( **listProducts** [countReceiptImages]);
**final** bytes = **await** file.readAsBytes(); <i>// Uint8List</i> **final** byteData = bytes. **buffer** .asByteData(); <i>// ByteData</i> **var** sharedData = **await** *platform* .invokeMethod( **"getSharedValue"** , byteData);

    }
  }

Code in Kotlin:

class MainActivity: FlutterActivity() {
    private val DATA_CHANNEL = "app.channel.shared.data"

    override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
        GeneratedPluginRegistrant.registerWith(flutterEngine);
        MethodChannel(flutterEngine.getDartExecutor().getBinaryMessenger(), DATA_CHANNEL).setMethodCallHandler { call, result ->
            if (call.method!!.contentEquals("getSharedValue")) {

                var argData = call.arguments
                val arrayInputStream = ByteArrayInputStream(argData as ByteArray?)
                val bitmap = BitmapFactory.decodeStream(arrayInputStream)

            }
        }
    }
}
