TabHeaderExtentBehavior enum

Defines how tab headers are sized relative to each other along their extent (the thickness of the header).

Depending on the tab placement:

  • For tabs placed horizontally (top or bottom), the extent is the height.
  • For tabs placed vertically (left or right), the extent is the width.
  • For stacked vertical tabs, the extent is again the height.

A tab header refers only to the inner area of a tab (label, optional buttons, and padding), excluding borders and external decorations.

This setting only affects the relationship between tab headers themselves. It does not control how the overall tabs area fits within its container — for that, see TabsAreaCrossAxisFit.
