Grid class

A widget that renders a static 2D grid of customized GridCells.

It acts like a tile map, copying characters and styles from the provided 2D array directly into the local draw buffer up to the active constraints.

Example Usage

final map = Grid([
  [GridCell('█', Style(foreground: Color(0xFF00FF00))), GridCell(' ', Style.empty)],
  [GridCell(' ', Style.empty), GridCell('█', Style(foreground: Color(0xFF00FF00)))],
]);
