How to restore location of page?

[livewater009]

Hi,

I have saved current location when page will be disappear. Then when user will open book, I want to restore current page (setLocation) of book again.

const [location, setLocation] = useState<Locator | Link>();
<ReadiumView
            ref={ref}
            file={file}
            location={location}
            settings={settings}
            onLocationChange={(locator: Locator) => setLocation(locator)}
            onTableOfContents={(toc: Link[] | null) => {
              if (toc) {
                setToc(toc);
              }
            }}
          />

It looks like that I need to call setLocation() function after readiumview is completed loading. But I can't find any props function to detect page or book is loaded.

Also how can I get current / total page number ?
Thanks.

1. open publication at a location:

You can use initialLocation in the file prop which should open the publication at the correct page on the initial render.

There is no harm in you also passing it into location but I think this gets ignored on the initial render so you generally need to at least use file.initialLocation.

If you need to jump to another page later, such as the user presses a button to jump to a different chapter, then you'd pass this through location.

2. current / total page number:

I don't think this is currently supported. The locator has locations within it from which you can calculate percentages of how far the user is through the publication.

I can see there are open PRs like #68 and #69 which allow access to additional metadata but they aren't currently merged.

Hi @TechWilk Thanks for your reply.
Everything is working as well for iOS now. But for android, it's not displaying any page. I am using LDPlayer simulator now.

Do you have any idea to fix it? I can't see any errors on android studio.

Best Regards.
