painter

A simple flutter widget to paint with your fingers.

Features

The widget supports:

• Changing fore- and background color
• Changing the thickness of lines you draw
• Exporting your painting as png
• Undo drawing a line
• Clearing the whole drawing
• Check if anything was drawn at all (using `PainterController.isEmpty')
• Erase Mode

Some Notes

• After calling 'finish()' on a PainterController you can't draw on this painting any more
• To create a new painting after finishing the old one simply create a new PainterController
• Calling 'finish()' for the first time will render the drawing. Successive calls will then return a cached version of the rendered picture

Example

For a full example take a look at the example project. Here is a short recording showing it. Note that the color picker is an external dependency which is only required for the example.
