Flutter signature pad widget #
Flutter widget to allow users to sign with finger and export the result as image.
Getting Started with the widget #
This is a very simple widget that allow drawing by finger on a widget and be able to get the image back.
For very basic usage, please check the example file here
Signature( color: Colors.black,// Color of the drawing path strokeWidth: 5.0, // with backgroundPainter: null, // Additional custom painter to draw stuff like watermark onSign: null, // Callback called on user pan drawing key: null, // key that allow you to provide a GlobalKey that'll let you retrieve the image once user has signed );
Once you retrieved the SignatureState from your GlobalKey, you'll have access to this API:
clear: allow you to clear the area to start again
getData: allow you to retrieve the image
hasPoints: to know if user has sign or not
points: to retrieve the list of points of the signature
