levelPadding seems to do nothing

[Ricardo Pereira]

TreeViewTheme’s levelPadding is not working.

I’ll take a look to see what the problem is.

I confirm the same issue,
As originally I have an issue with level Indentation in RTL .. It keeps showing it from left on both RLT, LTR Views Layout Orientation, while also levelPadding does not help at all!

// To Re-Generate the case, you can use "Directionality" for Testing it
Directionality(
    textDirection: TextDirection.rtl,
    child: TreeView(.. ),
);

@kevin Any Suggestion?
