processImage static method

Image processImage(String iconPath, { double scaling = 0.65, })

Implementation

static img.Image processImage(String iconPath, {double scaling = 0.65}) {
  final bytes = File(iconPath).readAsBytesSync();
  final original = img.decodeImage(bytes);

  if (original == null) {
    throw "Could not decode splash image.";
  }

  // LOGIC: Create a 1152x1152 canvas (Android 12 requirement)
  // We scale the logo to the requested percentage (default 65%) of the canvas
  // to ensure it's inside the 'Safe Zone' circle.
  final canvasSize = 1152;
  final targetLogoSize = (canvasSize * scaling).toInt();

  final resizedLogo = img.copyResize(
    original,
    width: targetLogoSize,
    height: targetLogoSize,
  );
  final canvas = img.Image(
    width: canvasSize,
    height: canvasSize,
    numChannels: 4,
  );

  // Center the logo on the transparent canvas
  final offset = (canvasSize - targetLogoSize) ~/ 2;
  img.compositeImage(canvas, resizedLogo, dstX: offset, dstY: offset);

  return canvas;
