FxPinInput class
A configurable PIN/digit input widget.
Renders length individual digit cells in a row with auto-advance, backspace navigation, paste support, and shake animation on error. Supports external controller sync for custom keyboards via controller.
Layout note: Each cell uses
Flexible + AspectRatio(1)to be equally-sized and square. This requires the parent widget tree to provide a bounded height. Wrap in aSizedBox(height: ...)if the parent is height-unconstrained.
Use FxOtpInput for OTP verification flows that also need a resend countdown.
