All notable changes to this project will be documented in this file.

0.0.1 #

Color Interpolation APIs:
- drawLineColored: Bresenham line drawing with linear color gradients.
- fillTriangleColored: Scanline-based triangle rasterizer with 3-way vertex color interpolation (RGB Triangle).
- fillQuadColored: Bilinear quadrilateral rasterizer with 4-corner color interpolation (Bilinear Quad Gradient).
Per-Cell Style Overrides: Added a custom List<Style?> _styles override grid to the Canvas widget, allowing custom coloring on a per-cell basis while falling back to the default widget style.
Interactive Pause Control: Added a keyboard binding for the P key to pause/resume the shape rotations and radar sweeps in real-time, displaying [PAUSED] or [RUNNING] in the demo header.
High-Fidelity TUI Showcase:
- Styled the Analog Clock with custom amber ticks, steel face outlines, and sweeping color-coded hands.
- Colored the Radar scopes and cross-hairs in forest green, sweep lines in bright neon green, and fade-out blips in amber/orange.
- Integrated rotating outline and filled RGB triangles/quads using the new color interpolation APIs.

Gap-Free Rasterization:
- Replaced the edge-sweep triangle filler with a mathematically sound scanline rasterization algorithm to guarantee 100% solid fills with no empty cells or gaps at any rotation angle.
- Quad rasterization now splits the polygon into two adjacent scanline-rasterized triangles, ensuring zero-gap fills.
Project Renaming: Renamed the codebase/package from cli_experiment to termui in pubspec.yaml, package lock configuration, and all 86 project-wide Dart source imports.

Fixed sub-pixel coverage gaps inside the rotating triangles and squares where the lines would fan out and leave unfilled cells.
