'logicalSize.aspectRatio == imageSize.aspectRatio': is not true.

Excellent Package you got here! So I tried capturing invisible widget but I get this error which I can't fathom.

I used the same code used in the example

  IconButton(
      icon: Icon(Ionicons.barcode_outline),
      color: Colors.white,
      iconSize: deviceWidth / 18,
      onPressed: () {
        ScreenshotController screenshotController = ScreenshotController();
        screenshotController
            .captureFromWidget(Container(
                padding: const EdgeInsets.all(30.0),
                decoration: BoxDecoration(
                  border: Border.all(color: Colors.blueAccent, width: 5.0),
                  color: Colors.redAccent,
                ),
                child: Text("This is an invisible widget")))
            .then((capturedImage) {
          // Handle captured image
        });
      });

Would you please help me out here?

Edit: Turns out this only happens in debug mode and works fine in release. I don't know whether this is an intended behavior or not. If it is intended, then feel free to close this issue.

I'm also having this exact same behaviour
