linked_layouts 0.5.2

Create custom layout systems based on the multi-leader-multi-follower pattern.

0.5.2

• Added LayoutLeaderClient.tryGetTransformIn() and LayoutLeaderClient.tryGetPositionIn().

  • LayoutLink.getTransformIn() and LayoutLink.getOffsetIn() have been deprecated in favor of the new methods on LayoutLeaderClient. They will be removed in the 0.6.0 minor pre-release.

• Deprecated LayoutLeaderClient.scale getter in favor of LayoutLeaderClient.tryGetTransformIn() method.

  • Reverted LayoutLeaderClient.scale to use the old RenderView boundary logic, restoring behaviors broken in 0.5.1.
  • The deprecated getter uses incorrect logic: attempts to get the leader's scale in global coordinate space.
  • Migrating to LayoutLeaderClient.tryGetTransformIn() is highly advised, because the replacement returns a full transform from the leader to the specified render object (e.g. follower), avoiding hacky workarounds (i.e. RenderView boundaries).
  • LayoutLeaderClient.scale will be removed in the 0.6.0 minor pre-release.

• Fixed LayoutLeaderClient.size setter logic to handle detached render objects properly.

• Improved internal file structure.

0.5.1

• Added onClientDidLayout() method to LeaderLayoutLinkHandle.

  • Captures leader size and transform immediately upon completing layout.

• Optimized LayoutLink.getOffsetIn matrix calculations and tree traversals.

  • Implemented Lowest Common Ancestor (LCA) algorithm to find common parent nodes.
  • Added fast-paths for parent-child layout relationships.
  • Prunes upper-tree nodes above the LCA and avoids unnecessary matrix operations.

• Optimized leader transform tracking and validation performance.

  • Refactored leader validation logic into single-leader checks.
  • Removed redundant computation overhead when verifying layout state across multi-leader setups.

• Improved assertion efficiency in SlottedMultiLeaderLayoutLink.leaderForSlot.

• Improved re-scheduling logic in FrameCallbackScheduler.

• Improved changelog formatting.

0.5.0

• Fixed internal update order of RenderObjectWithOptionalLayoutLinkMixin.layoutLink, RenderObjectWithRequiredLayoutLinkMixin.layoutLink, RenderSlottedLayoutLeader.slot.

• Exposed public API LeaderLayoutLinkHandle to enforce encapsulation of didLeaderDoPaint and didLeaderDoLayout of LayoutLink. Access to those methods is now provided via LeaderLayoutLinkHandle instance methods.

• Exposed public API FollowerLayoutLinkHandle to encapsulate follower redepthing logic. Added a tryRedepthClient method.

• Introduced a shared RenderObjectWithLayoutLinkBaseMixin interface to make RenderObjectWithRequiredLayoutLinkMixin independant of RenderObjectWithOptionalLayoutLinkMixin.

• Declared LayoutLinkHandle final, and LayoutLink - base to prevent incorrect implementations.

• Added more documentation comments.

• Improved internal file structure.

0.4.0+1

• Added a proper package description to pubspec.yaml.

• Added placeholder package example.

0.4.0

• Extracted client registration logic from RenderLayout*Mixin into RenderObjectWith*LinkMixins.

• Added RenderObjectWithOptionalLayoutLinkMixin and renamed RenderObjectWithLayoutLinkMixin to RenderObjectWithRequiredLayoutLinkMixin.

• Added optional named schedulerBinding parameter to FrameCallbackScheduler for mocking purposes.

• Organized source file structure.

0.3.0

• Fixed RenderObject mutation error when attempting to schedule layout run during SchedulerPhase.persistentCallbacks.

• Optimized leader transforms and size checking.

• Added more user-friendly error messages across the library.

• Added registered leaders validation to LayoutLink.

• Internal code cleanup and refactoring.

0.2.0

• Fixed leader size not persisting across reattachments.

• Introduced RenderObjectWithLayoutLinkMixin.createLayoutClientInternal method to handle internal state. Implementers are expected to replace createLayoutClient with the new method.

• Refactored LayoutLeader into AbstractLayoutLeader and introduced SingleLayoutLeader and CustomLayoutLeader as replacements.

• Renamed LayoutLink.leaderOffsetIn to LayoutLink.getOffsetIn and made the method static.

• Fixed LayoutLeaderClient.scale wasn't DPI-aware. Now it looks for the nearest RenderView ancestor.

• Fixed LayoutLink transient frame callback was empty by mistake.

• Removed unnecessary assertions in LayoutLinkHandle.

0.1.0

• Initial version.
