1 betto_pdf_widgets

Flutter widgets that use the betto_pdfium package for displaying PDF documents.

1.1 Features

• PageViewer — zoom-aware single-page renderer (fit-page, fit-width, custom zoom) with search-match overlays
• ViewerController — ChangeNotifier for page navigation, zoom, and search state
• TocView — scrollable table of contents
• ThumbnailGrid — lazy-loading 2-column thumbnail grid
• AnnotationView — annotation list (notes + highlights) with toggle
• SearchView — search input with result list and context snippets
• InfoView — metadata and file-info panel

A lower-level PageView widget is also exported for callers that only need a single fit-to-width page render without zoom modes or a controller.

1.2 Theming

The widgets style themselves entirely from the ambient ThemeData — ColorScheme, TextTheme, and TextSelectionThemeData — rather than a package-specific theme extension. Register a ThemeData on your MaterialApp (or Theme) as you would for any other Flutter app and the PDF widgets follow it, including dark mode.

1.3 Usage

The example project provides a complete PDF viewer application, “Quietly”, built entirely from these widgets.

See the technical specification for architecture, widget-by-widget details, and the rendering pipeline.
