dart_board_canvas 1.1.0

Animated canvas feature - Use to mount animations to routes

dart_board_canvas

This one is for fun. It provides a way to expose a Route which reveals an indeterminate animated canvas.

This is meant for physics/visual simulations and demo's. If you want access to the canvas to draw something cool, this is it.

It's similar to the flutter "funvas" project, and is designed for quick and dirty graphics work. It does not provide shorthand like funvas does.
