[0.5.1+1] 10-06-2021

• Fixes logic that marks nodes to refresh

  Before only child nodes were getting marked as needing refresh, causing the grand children and it's subtrees not to refresh, breaking lines hierarchy.

[0.5.1] 10-06-2021

• Adds new refreshNode Feature to [TreeViewController]

• Updates TreeNode's [delete] and [clearChildren] logic

• Adds linesToBeDrawn check in shouldRepaint of [LinesPainter]

• New example App UI

[0.5.0] 30-05-2021

Reverts most changes from 0.4.0

• Removing the TreeViewController made nodes inside a different page or in a drawer to lose their state.

  • TreeViewController is back, all logic from _TreeViewState got moved back to it.

• Merged the utils methods into TreeNode (ancestors, descendants, ...).

• The TreeView no longer auto scrolls nodes.

  • Now scrolling has to be done by the user.

[0.4.0] 17-05-2021

Simplification of the TreeView API.

• Dropped TreeViewController and merged it's logic into [TreeViewState] to make the code less 'spaghetti'. Instead of the controller, use a [GlobalKey

  • Made [TreeViewState] not private anymore.

• New scrolling functionality.

  • Added [scrollController] optional property to [TreeView].

  • Added [shouldAutoScroll] property to [TreeView].

  • Added [scrollTo] method to [TreeViewState].

• Renamed ScopedTreeNode to TreeNodeScope.

• Renamed InheritedTreeView to _TreeViewScope.

• Removed reversedSubtreeGenerator from utils.dart as it was not being used.

[0.3.1] 16-04-2021

• Implemented rounded corners for connected lines.

[0.3.0] 15-04-2021

• [ExpandNodeIcon] and [NodeWidgetLeadingIcon] are able to expand/collapse leaf nodes.

• [TreeNode.children] changed from [List] to [Set] to avoid duplicate children.

• The [TreeViewController] received a new callback.

  • The new onAboutToExpand is useful to dynamically populate the [TreeView].

• Some performance improvements when expanding/collapsing nodes.

[0.2.1] 11-04-2021

• Added useBinarySearch option to TreeViewController.

• Many performance improvements by reducing the amount of loops that expandNode and collapseNode took.

[0.2.0] 31-03-2021

• Stable null safety release.

• Refactoring of the entire API:

  • The old API was very "janky" with AnimatedList, TreeView now uses ListView.custom under the hood.

  • New InheritedTreeView inherited widget is used under the hood to get access to TreeViewController and TreeViewTheme from TreeView.of() method.

  • New ScopedTreeNode inherited widget, to get a TreeNode from anywhere under it in the widget tree, every TreeNode has its own ScopedTreeNode.

  • New NodeWidgetLeadingIcon for a folder/file icon approach.

  • The TreeViewController is now a ChangeNotifier, to talk to TreeView more easily.

  • TreeNode received a delete() method that removes it from the tree and clear its relationships.

• Extracted the main implementation of TreeViewController to a base class to be able to change the expansion of a node without notifying listeners.

  • Added some tests to TreeViewControllerBase.

• Updated NodeWidget to a Row instead of a ListTile

  • ListTile had some errors when using LinesWidget as leading.

• Dropped support for selecting/disabling nodes as it was getting very complicated and "hacky" to manage.

• Dropped TreeLine.link as it was complicating the indentation of nodes.

• Plus Many upgrades and fixes.

[0.1.0-nullsafety.0] 12-02-2021

• First release.
