CodePudding user response：

cell2.style.backgroundImage =

This is where I would start. You are not using the photo as an object. You have chosen to use the image as a style. The style would require calling the storage location vs treating the photo as an object.

• Example. I painted the wall. Error where is the paint can.
• Example. I put the paint can in the cubby hole. View/Display paint can.

CodePudding user response：

Under the command line you mentioned, I can add the image in the image folder with the asset to the cell in the pdf table. But I couldn't add the photo I took from the camera.

 PdfGridCell cell2 = row.cells[2];
 grid.rows[2].height = 200;
 cell2.imagePosition = PdfGridImagePosition.stretch;
 cell2.style.backgroundImage =
    PdfBitmap(await  _readImageData( 'urban-logo.jpg'),);
    Rect.fromLTWH(0, 0, 0, 0);
grid.draw(page: page, bounds: const Rect.fromLTWH(0, 0, 0, 0)) ;

Can you write your answer in a little more detail?enter code here
