TreeTheme class
Theme configuration for TreeView appearance and behavior.
TreeTheme defines the visual styling and behavioral options for tree view components including branch lines, padding, expand icons, and selection modes. All properties are optional and fall back to theme defaults when not specified.
Example:
ComponentTheme<TreeTheme>(
data: TreeTheme(
branchLine: BranchLine.path,
padding: EdgeInsets.all(12),
expandIcon: true,
allowMultiSelect: true,
recursiveSelection: true,
),
child: TreeView(...),
)
