clearControlPoints method
Clears all control points from a connection.
This reverts the connection to using its default algorithmic path.
Automatically invalidates the connection's cached path to trigger a repaint.
Does nothing if the connection doesn't exist.
Parameters:
connectionId: The ID of the connection to modify
Example:
controller.clearControlPoints('conn1');
Implementation
void clearControlPoints(String connectionId) {
final connection = _connections.firstWhere(
(c) => c.id == connectionId,
orElse: () => throw ArgumentError('Connection $connectionId not found'),
);
runInAction(() {
connection.controlPoints = [];
});
// Invalidate cached path
_connectionPainter?.pathCache.removeConnection(connectionId);
}
