Classes

USignatureController

Controls and holds the state of a USignaturePadRaw. Strokes get a velocity-variable width for a natural pen feel, and can be undone, redone, cleared and exported to a PNG.

USignaturePad

A fully featured, pure-Dart signature pad: velocity-variable strokes, undo / redo / clear, an optional colour picker and width slider, and PNG export. Fires onSave with the captured PNG whenever a stroke completes.

USignaturePadRaw

The bare drawing surface: captures pointer input and paints the strokes.
