const PortTheme({ required Size size, required Color color, required Color connectedColor, required Color highlightColor, required Color highlightBorderColor, required Color borderColor, required double borderWidth, MarkerShape shape = MarkerShapes.capsuleHalf, TextStyle? labelTextStyle, double labelOffset = 4.0, })

Creates a port theme with the specified visual properties.

All parameters are required to ensure consistent theming across different port states.

Parameters:

• size: The size of the port in logical pixels (width, height)
• color: Default color when the port is idle

• highlightColor: Color when port is highlighted during connection drag
• highlightBorderColor: Border color when port is highlighted
• borderColor: Color of the port's border
• borderWidth: Width of the port's border in logical pixels
• labelTextStyle: Text style for port labels
• labelOffset: Distance from port center to label (default: 8.0)

Note: Port label visibility is controlled by:

• Port.showLabel on each port instance
• The LOD (Level of Detail) system via DetailVisibility.showPortLabels
