StepConnectionStyle class

Step connection style (90-degree turns without rounded corners)

Creates connections with sharp 90-degree turns that follow a predictable step pattern based on port positions.

bendThreshold → double: Get bend detection threshold angle in radians Used for detecting significant direction changes in the path
no setteroverride
defaultHitTolerance → double: Default hit tolerance for this connection style Some styles may need different tolerances based on their geometry
no setterinherited
displayName → String: Human-readable display name
no setteroverride
hasExactBendPoints → bool: Whether this connection style has predictable bend points that can be calculated exactly
no setteroverride
hashCode → int: The hash code for this object.
no setterinherited
id → String: Unique identifier for this connection style
no setteroverride
isBuiltIn → bool: Available on ConnectionStyle, provided by the ConnectionStyleExtension extension
Check if this is a built-in connection style
no setter
minBendDistance → double: Get minimum distance between bend points as multiplier of tolerance
no setteroverride
needsBendDetection → bool: Whether this connection style needs bend detection for hit testing optimization
no setteroverride
runtimeType → Type: A representation of the runtime type of the object.

createHitTestPath(Path originalPath, double tolerance) → Path: Creates an expanded path for hit testing The base implementation provides a simple stroke-based expansion
override
createOptimizedHitTestPath(List<Offset> waypoints, double tolerance) → Path: Create optimized hit test path from exact waypoints
createPath(ConnectionPathParameters params) → Path: Creates the geometric path for drawing this connection This is the main responsibility of each connection style
override
getExactBendPoints(ConnectionPathParameters params) → List<Offset>?: Get exact bend points for styles that support it (e.g., step connections) Returns null if the style doesn't support exact bend point calculation
override
getSampleCount(double pathLength) → int: Get number of samples to use for bend detection based on path length
override
isEquivalentTo(ConnectionStyle other) → bool: Check if two connection styles are equivalent This is used for caching decisions and theme comparisons

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

toString() → String: A string representation of this object.
