BuildHeader class

A widget that builds the header for a side sheet.

The header includes a back button, a title, and a close button. The back button is optional and can be shown or hidden using the showBackButton parameter. The title is optional and defaults to 'Title' if not provided. The close button is optional and can be shown or hidden using the showCloseButton parameter. The onClose callback is called when the close button is pressed or when the back button is pressed and onClose is null. The backButtonTooltip and closeButtonTooltip parameters can be used to provide tooltips for the back and close buttons, respectively. The padding parameter can be used to specify the padding around the header.
