ScannerEffect class

A scanning line sweeps across the text revealing characters.

Characters are revealed via clip as the scan passes, with a bright color highlight and trailing glow effect.

ScannerEffect({Duration duration = const Duration(milliseconds: 1200), Curve curve = Curves.easeInOut, Color scanColor = Colors.cyan, double scanWidth = 0.15, double glowWidth = 0.3, Duration delayBetweenChars = Duration.zero}): Creates a scanner-style reveal animation.
