Methods

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
calculatePageFitMatrix({required int pageNumber, double? padding}) → Matrix4?: Calculate the matrix that corresponding to the page position.
calculatePageMatrix({required int pageNumber, double? padding, double x = 0.5, double y = 0.5, PdfViewerAnchor anchor = PdfViewerAnchor.center, double? zoomRatio}) → Matrix4?: Calculate the matrix that corresponding to the page of specified offset (x, y) and specified zoomRatio.
clampX(double x, double zoomRatio) → double: Clamp horizontal scroll position into valid range.
clampY(double y, double zoomRatio) → double: Clamp vertical scroll position into valid range.
dispose() → void: Discards any resources used by the object.
inherited
getFullSize(double zoomRatio) → Size: Get the full PDF content size in the PdfViewer with the specified zoomRatio.
getPage(int pageNumber) → Future<PdfPage>: Get the page.
getPageRect(int pageNumber) → Rect?: Get page location. If the page does not exist in the layout, it returns null.
getScrollableMaxX(double zoomRatio) → double: Calculate maximum X that can be acceptable as a horizontal scroll position.
getScrollableMaxY(double zoomRatio) → double: Calculate maximum Y that can be acceptable as a vertical scroll position.
goTo({Matrix4? destination, Duration duration = const Duration(milliseconds: 200)}) → Future<void>: Go to the destination specified by the matrix.
goToPage({required int pageNumber, double? padding, Duration duration = const Duration(milliseconds: 500)}) → Future<void>: Go to the specified page.
goToPointInPage({required int pageNumber, double? padding, double x = 0.5, double y = 0.5, PdfViewerAnchor anchor = PdfViewerAnchor.center, double? zoomRatio, Duration duration = const Duration(milliseconds: 500)}) → Future<void>: Go to specific point in page.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
setZoomRatio({required double zoomRatio, Offset? center, Duration duration = const Duration(milliseconds: 200)}) → Future<void>: Set zoom ratio.
toScene(Offset viewportPoint) → Offset: Return the scene point at the given viewport point.
inherited
toString() → String: A string representation of this object.
inherited
zoomMatrix(double zoomRatio, {Offset? center}) → Matrix4: Calculate the matrix that changes zoom ratio.

Operators

operator ==(Object other) → bool: The equality operator.
