Static Properties

getNode ↔ GetNode

This function is used to get the node from the node id.

getter/setter pair

Static Methods

calculateGlobalRotatedBoxTopLeft(String id, {bool unrotate = true, required NodeBoundaryType boundaryType, bool updatingSortedNodeList = false}) → Vec

unrotate will unrotate the top-left corner of the rotated box to the top-left corner of the bounding box.

calculateSortedGlobalRotatedBoxTopLeft(String id, {bool unrotate = true, required NodeBoundaryType boundaryType}) → Vec

unrotate will unrotate the top-left corner of the rotated box to the top-left corner of the bounding box.

registerNodeGetter(GetNode getNode) → void

This function is used to initialize the getNode function.

resolveConstraints(BaseNode node, {SizeFit? horizontalFit, SizeFit? verticalFit}) → BoxConstraintsModel

There's the normal constraints field, but those constraints don't tell the full story of the provided node's true constraints.

sortNodes(List<BaseNode> nodes, {bool reversed = false}) → void

Sorted nodes is a list of nodes that go from parent -> child using a merge sort with memoization.

updateGlobalRotation({required BaseNode node, required int newRotationDegrees, bool updateChildren = true}) → void

Update the global rotation for given node with newRotationDegrees.

updateNode({required BaseNode node, EdgeInsetsModel? margin, EdgeInsetsModel? padding, AlignmentModel? alignment, OuterNodeBox? outerBoxLocal, OuterNodeBox? outerBoxGlobal, NodeBox? basicBoxLocal, BoxConstraintsModel? constraints, BoxConstraintsModel? resolvedConstraints, int? rotationDegrees, bool resetRetainedBox = true, bool recursivelyCalculateChildrenGlobalBoxes = true, Vec? globalParentBoundingBoxPos, bool updatingSortedNodeList = false}) → void

updateNode is responsible for updating the node and its children when one or more of its properties change. Ex. if margin is changed, all the node boxes and node's children are updated accordingly.
