Render one page at a time (pageFling) instead of continuous rendering of pages

[cyberneid]

The current version renders the pages in continuous mode. i.e. you can have the bottom of page 1 above and the top of page 2 below. AndroidPdfViewer instead allows flinging a single page at a time (with pageFling property).

 /** Spacing between pages, in px */
    private int spacingPx = 0;

    /** Add dynamic spacing to fit each page separately on the screen. */
    private boolean autoSpacing = false;

    /** Fling a single page at a time */
    private boolean pageFling = true;

See this class:

Can you add such a feature too?

Would be very useful for us, we used the pdf render textures from pdf_render for this, hard to switch over without something equivalent.

For Texture or such widget, I opened #41.

For page flinging, if I introduce some kind of Texture or such, I think carousel_slider or such is enough. Do you agree?

[cyberneid]

Yes carusel_slider may be a good option but with vertical scrolling

0.4.23 introduces PdfDocumentViewBuilder and PdfPageView.

@cyberneid
PdfPageView can be used within other carousel like widget and I think it's enough for such use case.
Please check it and if you have any questions, please ask me!
