Hi Rithika,

We appreciate your patience.

We have included the fix for “Giving wrong search results for a particular document” in our latest weekly NuGet release, so kindly upgrade to the latest version v19.3.46 to get the issue resolved.
Package link: https://pub.dev/packages/syncfusion_flutter_pdfviewer/versions/19.3.46-beta
and we included the fix for the text selection not working properly for a particular document in our latest version.

On further analyzing, we found that the provided document contains a rotated glyph for some words. Currently, SfPdfViewer doesn't provide text selection for rotated glyphs in word, so text selection is not working on few pages. We are analyzing on this feature and will update the further details on 22 October 2021.

Hi Rithika,

At present we do not have text selection support for rotated TextGlyphs in Flutter SfPdfViewer. We do not have any immediate plans to implement this feature. At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest. We will let you know when this feature is implemented. The status of the features can be tracked using the following link.
