# Understanding electronic and digital signatures

Nutrient Flutter SDK allows users to sign a document electronically using the built-in user interface. End users can tap a signature element, which will open a popover, allowing them to draw or type a signature or select an image to sign the document with.

To sign a document, you need to have the Electronic Signatures component enabled in your license.
