Do you have a plan to add lazy load to the widget in the future?

I think loading speed is acceptable with those pdfs that have less than 30 pages. The higher the page count is, the slower it gets. I myself try to open a 200 pages document and it slows down my phone dramatically and obviously took a long time to finish.
So I thinking about lazy load solution for the list thumbnails, and I can see in the code that it is possible to add this useful function to your widget.

I'll check what we can do.

I did it in my branch, I vastly changed the way it builds the thumbnail list. I'm new to Flutter, so I'm not sure if it is the best practice to do it. But it works well as it is expected.

@tranhuudang no problem, just open a PR so I can check.

Added caching and updated the documentation.
