Usage

Here's an example of how to use the NativeViewWidget in your Flutter application:

    Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: Stack(
          children: [
            NativeViewWidget(
                onScanError: _onScanError,
                onCodesReceived: _onCodesReceived,
                onDetectionResult: _onDetectionResult,
                onOCRImagesReceived: _onOCRImagesReceived,
                shouldDisplayFocusImage: true,
                shouldScanInFocusImageRect: true,
                onDetected: onDetected,
                isTextIndicationOn: true,
                isBarCodeOrQRCodeIndicationOn: true,
                selectionTintColor: 'white',
                imageTintColor: 'white',
                codeDetectionConfidence: 0.5,
                sessionPreset: 'high',
                nthFrameToProcess: 10,
                captureMode: 0,
                captureType: 0,
                scanMode: 0,
                focusImage: '',
                focusImageRect: const {
                  'x': 0,
                  'y': 0,
                  'height': 0,
                  'width': 0,
                }),
            Positioned(
              left: 0,
              right: 0,
              bottom: 0,
              child: Padding(
                padding: const EdgeInsets.all(16.0),
                child: Container(
                  alignment: Alignment.bottomCenter,
                  width: double.infinity,
                  color: Colors.white,
                  padding: const EdgeInsets.all(16),
                  child: Column(
                    children: [
                      Text(
                        'Detected Type: $detectedType',
                        style:
                            const TextStyle(color: Colors.black, fontSize: 16),
                      ),
                      Text(
                        'Scanned Code: $scannedCode',
                        style:
                            const TextStyle(color: Colors.black, fontSize: 16),
                      ),
                      ElevatedButton(
                        onPressed: () {
                          const NativeViewWidget()
                              .onPressChangeCaptureMode('auto');
                        },
                        child: const Text('Change Capture Mode to Auto'),
                      ),
                      ElevatedButton(
                        onPressed: () {
                          const NativeViewWidget()
                              .onPressChangeCaptureMode('manual');
                          updateCaptureMode(true);
                        },
                        child: const Text('Change Capture Mode to Manual'),
                      ),
                      ElevatedButton(
                        onPressed: () {
                          const NativeViewWidget()
                              .onPressChangeScanMode('qrcode');
                        },
                        child: const Text('Change Scan Mode to QR Code'),
                      ),
                      ElevatedButton(
                        onPressed: () {
                          const NativeViewWidget()
                              .onPressChangeScanMode('barcode');
                        },
                        child: const Text('Change Scan Mode to Barcode'),
                      ),
                      ElevatedButton(
                        onPressed: () {
                          const NativeViewWidget().onPressChangeScanMode('ocr');
                        },
                        child: const Text('Change Scan Mode to OCR'),
                      ),
                      if (isManualCaptureMode)
                        ElevatedButton(
                          onPressed: () {
                            const NativeViewWidget().onPressCapture();
                          },
                          child: const Text('Capture Photo'),
                        ),
                    ],
                  ),
                ),
              ),
            ),
          ],
        ),
      ),
    );
  }

User can make the Barcode or Qrcode window customizable by giving values here :

 focusImageRect: const {
                  'x': 0,
                  'y': 0,
                  'height': 0,
                  'width': 0,
                }

This will show us either the detected type is Text, QrCode or BarCode:

                Text(
                'Detected Type: $detectedType',
                style:
                const TextStyle(color: Colors.black, fontSize: 16),
                ),

This will show us the scanned code from barCode and QrCode:

                Text(
                'Scanned Code: $scannedCode',
                style:
                const TextStyle(color: Colors.black, fontSize: 16),
                ),

This will change the scanning mode to Auto:

                onPressed: () {
                const NativeViewWidget()
                .onPressChangeCaptureMode('auto');
                },

This will change the scanning mode to Manual:

                onPressed: () {
                const NativeViewWidget()
                .onPressChangeCaptureMode('manual');
                updateCaptureMode(true);
                },

This will change the Scan Mode to QR:

                onPressed: () {
                const NativeViewWidget()
                .onPressChangeScanMode('qrcode');
                },

This will change the Scan Mode to BarCode:

                onPressed: () {
                const NativeViewWidget()
                .onPressChangeScanMode('barcode');
                },

This will change the Scan Mode to OCR:

                onPressed: () {
                const NativeViewWidget()
                .onPressChangeScanMode('ocr');
                },

Additional information

Users can import this package and integrate it into their Flutter projects to enable barcode and QR code scanning with customizable modes. This package provides a simple and efficient way to leverage the power of the Flutter Vision SDK in your applications.
