Description:

This is a re-open of #22 which was closed (I can't reopen issues because I am not a collaborator on the project), but this still is an issue. Here are more details and concrete example to reproduce:

tooltipBehavior: TooltipBehavior(
	enable: true,
	header: 'Tooltip Header',
	format: "point.x has value of: point.y",
),

Code To Reproduce:

As you can see from the above, point.y does not get replaced. Please run this simple main.dart to reproduce. All the code lives within it, attached below as txt file:
