decodeImageFromList and decodeImageFromPixels returns Error: [object Event] at Object.createErrorWithStack #49244
Description
So I'm taking a screenshot of a VideoElement like this:
CanvasElement canvas = CanvasElement(width: _videoElement.videoWidth, height: _videoElement.videoHeight);
canvas.context2D.drawImage(_videoElement, 0, 0);
ImageData imgData = canvas.context2D.getImageData(0, 0, canvas.width, canvas.height);
Then show it like this:
_pauseCanvas = CanvasElement(width: _videoElement.videoWidth, height: _videoElement.videoHeight);
_pauseCanvas.context2D.putImageData(imgData, 0, 0);
That part works perfectly.
The problem is that I'd prefer to use an Image widget instead of a CanvasElement to reuse some parts of the code on native, but decodeImageFromList don't take a Uint8ClampedList which is what I have from the ImageData and when I use:
imgData.data.buffer.asUint8List() or Uint8List.fromList(imgData.data)
I get that error:
Event {isTrusted: true, Symbol(_jsError): Error: [object Event]
at Object.createErrorWithStack (http://localhost:57523/packages/build_web…, type: "error", target: img, currentTarget: img, …}
It's possible that I don't do the right thing, but I don't have an error that helps me to find what I'm doing wrong. Also tried decodeImageFromPixels but I get similar results.
