flutter_folderview 0.5.3

A customizable Flutter widget for displaying hierarchical data in tree and folder views with rich theming support.

0.5.3

• fix: Recursively collect parent nodes from nested folders in tree mode

0.5.2

• perf: Replace setState with ValueNotifier for horizontal scroll offset and hover state to prevent full widget tree rebuilds
• perf: Eliminate recursive list spreading in FlattenService.flatten() by reusing a single mutable list with add/removeLast pattern

0.5.1

• fix: Show full text on horizontal scroll instead of ellipsis-truncated text using OverflowBox

0.5.0

• BREAKING CHANGE: Remove isExpanded property from Node<T> model - nodes are now immutable
• BREAKING CHANGE: Add expandedNodeIds parameter to FolderView, FolderViewContent, and NodeWidget for external expansion state management
• BREAKING CHANGE: Update SizeService methods to accept expandedNodeIds parameter
• perf: Add incremental expand/collapse with expandNode() and collapseNode() methods in FlattenService
• perf: Implement text width caching via _textWidthCache to reduce expensive TextPainter layout calls
• perf: Add lazy content width measurement - calculate as nodes render instead of upfront O(N) traversal
• perf: Optimize scroll performance for 20k+ nodes with Transform.translate and itemExtent on ListView.builder
• fix: Clamp scroll offset to valid range instead of skipping sync when out of range
• fix: Preserve scroll position on bulk expand/collapse (expandAll/collapseAll) using viewport anchor node

0.4.0

• feat: Add labelResolver to FolderNodeTheme, ParentNodeTheme, ChildNodeTheme for dynamic label resolution based on node.data
• fix: Update animation controller duration in didUpdateWidget when theme animationDuration changes at runtime

0.2.4

• feat: Add labelResolver to all node themes for dynamic label display

0.2.3

• feat: Add color and expandedColor properties to ExpandIconTheme for expand icon color theming

0.2.2

• refactor: Unified expand icon logic to ensure consistent node layout alignment
• refactor: Add isChild parameter to _buildExpandIcon for proper child node spacing

0.2.1

• feat: Add hoverColor, splashColor, and highlightColor properties to all node themes for interaction color theming
• feat: Add comprehensive tooltip support with NodeTooltipTheme class for all node types
• feat: Add rowHeight property to FlutterFolderViewTheme for configurable row height
• feat: Add rowSpacing property to FlutterFolderViewTheme for vertical spacing between rows
• refactor: Remove iconToTextSpacing property from all node themes - now controlled via icon margin.right

0.2.0

• BREAKING CHANGE: Migrate from unified FolderViewTextTheme and FolderViewIconTheme to node-type specific themes (FolderNodeTheme, ParentNodeTheme, ChildNodeTheme, ExpandIconTheme)
• feat: Add custom Widget? support for each node type instead of hardcoded Icon widgets
• feat: Add openWidget property for folder nodes (displayed when expanded)
• feat: Add padding and margin properties for each widget type
• feat: Add clickInterval property to ChildNodeTheme for configurable double-click detection (default: 300ms)
• feat: Add animationDuration property to FlutterFolderViewTheme for configurable expand/collapse animation speed
• feat: Add theme resolver functions (widgetResolver, textStyleResolver, selectedTextStyleResolver, openWidgetResolver) for dynamic styling based on node data
• feat: Add generic type support <T> to all theme classes for type-safe access to node.data

0.1.2

• fix: Fixed scroll position being reset when expanding/collapsing nodes by removing contentHeight from SyncedScrollControllers key

0.1.1

• fix: Fixed scroll position calculation when switching between view modes or expanding/collapsing nodes

0.1.0

• feat: Add dual view modes (Tree and Folder)
• feat: Add three node types (Folder, Parent, Child) for flexible hierarchy representation
• feat: Add multiple line styles (Connector, Scope, None) for visual tree structure
• feat: Add comprehensive theming system (icon, text, line, scrollbar, spacing, node style)
• feat: Add interactive features (selection, tap handlers, expand/collapse animations)
• feat: Add synchronized horizontal and vertical scrolling with custom scrollbars
• feat: Add depth-based indentation for nested nodes
• fix: Correct indent and line positioning for nested nodes based on depth level
