The function 'getRed' isn't defined. Try importing the library that defines 'getRed', correcting the name to the name of an existing function, or defining a function named

 Float32List _imageToByteListFloat32(imglib.Image image) {
 var convertedBytes = Float32List(1 * 112 * 112 * 3);
 var buffer = Float32List.view(convertedBytes.buffer);
 int pixelIndex = 0;
for (var i = 0; i < 112; i++) {
  for (var j = 0; j < 112; j++) {
    var pixel = image.getPixel(j, i);
    buffer[pixelIndex++] = (imglib.getRed(pixel) - 128) / 128;
    buffer[pixelIndex++] = (imglib.getGreen(pixel) - 128) / 128;
    buffer[pixelIndex++] = (imglib.getBlue(pixel) - 128) / 128;
  }
}
return convertedBytes.buffer.asFloat32List();

}

-------------Above is the function to convert image to byte list Float32

Float32List imageAsList = _imageToByteListFloat32(img);

---------------- This is how i am calling the above function..

In the below version of image the code is working well
---image: 3.1.3
but after updating the image version to
---image: ^4.2.0

the imglib.getRed , imglib.getGreen , imglib.getBlue property is not working

how to solve this issue and get the same functionality as above code is serving thanks in advance ...

  Float32List _imageToByteListFloat32(imglib.Image image) {
   var convertedBytes = Float32List(1 * 112 * 112 * 3);
   var buffer = Float32List.view(convertedBytes.buffer);
    int pixelIndex = 0;

for (var i = 0; i < 112; i++) {
  for (var j = 0; j < 112; j++) {
    int pixel = image.getPixel(j, i) as int;
    // Extract RGBA components from pixel value
    int r = (pixel >> 24) & 0xFF;
    int g = (pixel >> 16) & 0xFF;
    int b = (pixel >> 8) & 0xFF;

    // Normalize and store pixel values
    buffer[pixelIndex++] = (r - 128) / 128.0;
    buffer[pixelIndex++] = (g - 128) / 128.0;
    buffer[pixelIndex++] = (b - 128) / 128.0;
  }
}
return convertedBytes.buffer.asFloat32List();

}

solved by replacing the code as above
