onSelection property

EpubSelectionCallback? onSelection

Callback when text is selected with WebView-relative coordinates.

Fires when:

• User completes initial text selection
• User finishes dragging selection handles (after a 300ms debounce)

Use this callback to display custom UI at the selection position. Coordinates are relative to the WebView, not the screen.

See also:

• onSelectionChanging - Called while user is actively dragging handles
• onDeselection - Called when selection is cleared

Implementation

final EpubSelectionCallback? onSelection;
