I created a pdf document in my flutter project. but the checkbox won't show up. The row has space in front of the text, but it is blank, no checkbox or anything. This happened after I updated the pdf package dependency and starting from there the checkbox won't show up. At first, before I update the package, the checkbox shows up but the checkbox doesn't have a mark even if I set the value to true, the exported pdf only has box but not highlighted, I tried going back to the package version before I update it where it at least shows the checkbox, but any other version is the same, the checkbox did not show up ever again. What could be the cause?
Here is the class where I have the creation of pdf:
