operator == method

@override bool operator ==(Object other)

Compares the builders, so components built with the same ones are equal.

A builder written as an inline closure is a new object on every build and never compares equal. Pass a top-level or static function to keep two instances equal, which is what stops the tiles rebuilding.

ScheduleTileComponents restricts several of these to null, so the types are compared too rather than only the fields.

Implementation

@override
bool operator ==(Object other) {
  if (identical(this, other)) return true;

  return other is TileComponents &&
      other.runtimeType == runtimeType &&
      other.tileBuilder == tileBuilder &&
      other.overlayTileBuilder == overlayTileBuilder &&
      other.tileWhenDraggingBuilder == tileWhenDraggingBuilder &&
      other.feedbackTileBuilder == feedbackTileBuilder &&
      other.dropTargetTile == dropTargetTile &&
      other.dragAnchorStrategy == dragAnchorStrategy &&
      other.resizeDragAnchorStrategy == resizeDragAnchorStrategy &&
      other.resizeHandlePositioner == resizeHandlePositioner &&
      other.verticalResizeHandle == verticalResizeHandle &&
      other.horizontalResizeHandle == horizontalResizeHandle;
