Griddle simplifies to concept of creating 2D games or UI applications within
a 2D-matrix, or grid, which in turn makes it a suitable cross-platform
graphics framework for lower fidelity games or apps.

It is inspired by:


Creating simple 2D programs that run inside a terminal (or terminal emulator) is
complicated. The goal of griddle is to abstract a terminal-like screen into
a 2D grid of character cells

Like termpixels, this project makes the terminal more
accessible and more fun, but in Dart!

NOTE: To learn more about the design of griddle, view


import 'dart:math' as math;

import 'package:griddle/griddle.dart';

void main() {
  final screen = Screen.terminal(Terminal.usingAnsiStdio());
  const string = 'Hello World, from Griddle for Dart!';

  screen.onFrame.listen((_) {

    for (var i = 0; i < string.length; i++) {
      final t = / 1000;
      final f = i / string.length;
      final c = Color.fromHSL(f * 300 + t, 1, 0.5);
      final x = screen.width ~/ 2 - string.length ~/ 2;
      final o = math.sin(t * 3 + f * 5) * 2;
      final y = (screen.height / 2 + o).round();

      screen.print(string[i], x + i, y, foreground: c);

This package welcomes new issues and pull requests.

Changes or requests that do not match the following criteria will be rejected:

  1. Common decency as described by the Contributor Covenant.
  2. Making this library brittle/extensible by other libraries.
  3. Adding platform-specific functionality.
  4. A somewhat arbitrary bar of “complexity”, everything should be easy to use.
