Usage

Basic

Draw

The very first step for draw_your_image is to place Draw widget at anywhere you want in the widget tree.

final _controller = DrawController();

@override
Widget build(BuildContext context) {
    return Draw(
        controller: _controller,
        backgroundColor: Colors.blue.shade50,
        strokeColor: Colors.red,
        strokeWidth: 8,
    );
}

Draw widget would display a simple canvas which users can draw whatever they want with given strokeColor and strokeWidth.

If you change colors or width, you can simply manage states representing them in your widgets, maybe StatefulWidgets, and path it to the properties of Draw.

For undo(), redo() or other actions, pass instance of DrawController and pass it to controller property. See DrawController section below for detail.

DrawController

DrawController provides interfaces to control canvas. Below are provided methods

• undo() will undo the last stroke. It returns false if no stroke can be performed.
• redo() will redo the last performed undo stroke. It returns false if no stroke can be performed.
