flutter_fancy_tree_view 0.2.0

A highly customizable TreeView Widget for visualization of nested data in Flutter.

[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.
