I'm trying to make a puzzle and I have a Stack with multiple images overlayed on top of each other. Every puzzle piece image has transparent parts allowing all the puzzle parts to appear to fit snuggly together. However, it seems like despite the transparency, each piece still maintains the original image dimensions and prevents me from tapping any other pieces below them in the stack.

Is there a way, other than manually clipping all these pieces, to have flutter automatically ignore the transparent parts of images and allow gestures to only register on the non-transparent pieces themselves?
