Initial release of dynamic_table_scroll — a high-performance 2D data table widget for Flutter.

Features

• Sticky Column Headers: Freeze header titles at the top when scrolling vertically (isHeaderPinned).
• Pinned Frozen Columns: Anchor one or multiple leading columns on the left when scrolling horizontally (pinnedColumnCount, DynamicTableColumn.isPinned).
• Anchored Top-Left Corner: Stationary top-left corner cells on both scroll axes.
• Horizontal Column Virtualization (Windowing): Renders only visible columns in the viewport with configurable overscan buffers, delivering buttery-smooth 60/120 FPS performance even with 100+ to 200+ columns.
• Auto-Fit Column Widths: Automatically calculates column widths based on header and sample row measurements with minWidth and maxWidth constraints.
• High-Performance Unified Viewport: $O(1)$ fixed item extent list rendering optimized for massive datasets (10,000+ rows).
• GPU-Accelerated Scrolling: Hardware-translated horizontal layer scrolling without triggering unnecessary widget rebuilds.
• Bidirectional 2D Gestures: Synchronized drag gestures across touch, mouse wheel, and trackpad with native scrollbar support.
• Programmatic Controller: DynamicTableController for jumping or animating to specific rows and horizontal offsets.
• Full Styling & Density Support: DynamicTableStyle with DynamicTableStyle.compact(), zebra striping, sticky elevation shadows, customizable borders, paddings, and typography.
• Interactive Callbacks: Support for onRowTap, onRowLongPress, rowBuilder, and custom emptyWidget.
