TicketShape class

A widget that renders a ticket-shaped container with rounded corners and circular side notches — similar to a physical boarding pass or event ticket.

This widget both draws the ticket outline (using CustomPaint) and clips its child widget to the same path, ensuring the content fits perfectly within the ticket shape.

The ticket appearance is controlled by:

• borderRadius → Roundness of ticket corners.
• notchRadius → Radius of the circular notches on both sides.
• notchOffsetFactor → How much the notches are horizontally offset (a factor of the notch radius).
• borderColor and borderWidth → Define the ticket border.
• maxWidth → Restricts how wide the ticket can be drawn.

Typically used to display structured information such as flight tickets, concert passes, or coupon layouts.

Example usage:

TicketShape(
  borderColor: Colors.deepPurple,
  child: Padding(
    padding: const EdgeInsets.all(16),
    child: Column(
      mainAxisSize: MainAxisSize.min,
      children: [
        Text('Flight Ticket', style: Theme.of(context).textTheme.titleLarge),
        const SizedBox(height: 8),
        Text('Passenger: Jenny Simmons'),
      ],
    ),
  ),
)

This widget uses TicketPainter to draw the border and TicketClipper to clip its child content to the ticket outline.
