An inner widget tree cannot be bigger than a page: A Widget cannot be drawn partially on one page and the remaining on another page: It's insecable.
After visiting this official docs via https://pub.dev/documentation/pdf/latest/widgets/MultiPage-class.html. I found The Wrap Widget here is able to rearrange its children to span them across multiple pages. But a child of Wrap must fit in a page, or an error will raise.
Use case: I am trying to create the cv pdf where user input their data via form and the cv will be generated according to user input. In some cases like in experience section of Curriculum Vitae out of many sections, the input content exceeds the single page like in this image.
Note: Till today if Wrap or Column do not fit in a page it will give error like
Exception: This widget created more than 20 pages. This may be an issue in the widget or the document. OR
Exception: Widget won't fit into the page as its height (889.6392) exceed a page height (841.8897637795275). You probably need a SpanningWidget or use a single page layout
This overflow feature will be used in lot's of dynamic pdf generation and it is one of the most import feature in my project.
So, Now I want to know:
- Feasibility of this feature and
- If this feature is feasible, is there any plans to implement in near future?
@DavBfr I want to know the feasibility of this feature because this feature is the most important thing and highly dependent task in my project.
So, If this feature is feasible, is there any plan to implement in near future?
Please look at this _ExpWidget(..) which will contains dynamic content ,according to the work experience of the user. This _ExpWidget(..) might be bigger than one A4 page. So, when the content is bigger than page we will get this common issue :
Exception: This widget created more than 20 pages. This may be an issue in the widget or the document. See https://pub.dev/documentation/pdf/latest/widgets/MultiPage-class.html
After visiting this official docs it is clearly mention An inner widget tree cannot be bigger than a page: A Widget cannot be drawn partially on one page and the remaining on another page: It's insecable.
So, How to resolve this kind of dynamic content issues which might be greater than the page? This overflow feature will be used in lot's of dynamic content generation and it is one of the most import feature in my project.
This is the sample code from the example:

@DavBfr Will you please help me with this issue? I am waiting for your reply.
@jazzbpn I tested that, and yes it's not working like this. You can find another way to layout your document: do use the top-level MultiPage's children list to draw your text elements, use overflow: TextOverflow.span to allow the large texts to use multiple pages. Or you can sponsor me to make it work with this layout.

How much time will I need to wait for this feature? My project is completely depend upon this feature. Do you want me to sponsor more? If yes how much will It cost to make this work?
@jazzbpn If you want it to go faster, I can help you to make it work without this feature, usually there is another way around.
That sounds good. I want to know how?

Working! But how to resolve such kinds of issues in future? How will this type of issue occurs and what are the ways to resolve it? Will you please elaborate? Is this issue occurs because of child column?
Just found the new package https://pub.dev/packages/syncfusion_flutter_pdf But, here we need to build all widget on graphic level. This package will also not be helpful to create PDF where the content is dynamic.
@DavBfr Your library is much more easy to implement. So, Is there any way to add this feature or resolve this multipage issue soon?
Thanks, I try my best to make it easy. I'm still working on that issue, but it requires deep changes to the layout engine, which takes time, especially to keep the API compatible.
Any update on this issue?

Hello Dav, This is one of the most important features which will be needed for most of dynamic content creators. This features is easily available in all other libraries except dart. So, why are you ignoring such user segments. How much will it take to implement this feature? Is there anything we nee need to do to make this happen? Let me know. I already waited more than 1 year for this features.
Thank you! Regards Bipin

@DavBfr Will you please see this? https://stackoverflow.com/questions/70434570/an-inner-widget-tree-cannot-be-bigger-than-a-page-a-widget-cannot-be-drawn-part
Hello guys,
This issue is also affecting our project.
For now our solution is split the text in many pw.Text(...) widgets by each word, but we are concerned about memory consumption and performance for big PDFs.
Do you guys know any better way or hint about that topic?
Your library is really amazing and pretty easy to use.
Thank you
@niltonvasques With your Text widget, use the attribute overflow: span. It will automatically do that for you.
@DavBfr hey gorgeous developer once we worked on a project. I sponsored you to make me a couple of resume templates a few months ago in may. Now I am also facing this above mentioned issue. Please do some work to resolve this issue. We will be sponsoring you too as much as we can. I am ready to become your sponsor member on monthly basis but please do some work to resolve this issue forever. Also please provide me a work around to solve it. I also have emailed you about this. So need your serious attention on this issue.
The project that i am working on is very powerful it can generate high incomes as even i do not have to much pdf resume resources still it's getting ranked and now it is on 32 number in my country on playstore i will show you in email if you ask fo it. So please again i request you to provide a powerful solution to this annoying problem. Also after providing this your package will get top position in pdf libraries. Thanks in advance.
