Details

How to Reproduce:

• Modify ConfiguredPDFViewComponent like so:

class ConfiguredPDFViewComponent extends Component {
  render() {
    return (
      <View style={{ flex: 1 }}>
        <PSPDFKitView
          document={"PDFs/Annual Report.pdf"}
          configuration={{
            backgroundColor: processColor("lightgrey"),
            showThumbnailBar: "scrubberBar",
            showDocumentLabel: false,
            useParentNavigationBar: false,
            allowToolbarTitleChange: false,
+           pageMode: 'single',
+           pageTransition: 'scrollPerSpread'
          }}
          toolbarTitle={"Custom Title"}
          style={{ flex: 1, color: pspdfkitColor }}
        />
      </View>
    );
  }
}

• Go to the last page
• Rotate the device a few times

Expected:

The last page view should always be centered.

Actual:

The last page view will be layed out incorrectly.

Acceptance Criteria

• Fix the issue.
• When approved, right before merging, rebase with master and increment the package version in package.json, package-lock.json, samples/Catalog/package.json, and samples/NativeCatalog/package.json (see example commit: 1bf805f).
• Create a new release (and tag) with the new package version (see https://github.com/PSPDFKit/react-native/releases).
