ConnectionStyleOverrides class
Defines style overrides for a connection at the widget level.
ConnectionStyleOverrides allows customizing the appearance of individual connections without modifying the connection model or theme. These overrides are resolved at render time via a callback.
Usage
Provide a connectionStyleResolver callback to NodeFlowEditor:
NodeFlowEditor(
connectionStyleResolver: (connection) {
if (connection.data?['type'] == 'error') {
return ConnectionStyleOverrides(
color: Colors.red,
selectedColor: Colors.red.shade700,
strokeWidth: 3.0,
);
}
return null; // Use theme defaults
},
)
Override Cascade
Colors and styles are resolved in this order of precedence:
- Widget-level overrides from
connectionStyleResolver(if provided) - Theme colors (from ConnectionTheme)
Constructors
- ConnectionStyleOverrides({Color? color, Color? selectedColor, double? strokeWidth, double? selectedStrokeWidth})
-
Creates connection style overrides.
