Defines how the bounds of the selected tab indicator are computed.
- label → const TabBarIndicatorSize
The tab's bounds are only as wide as the (centered) tab widget itself.
This value is used to align the tab's label, typically a Tab widget's text or icon, with the selected tab indicator.
- tab → const TabBarIndicatorSize
The tab indicator's bounds are as wide as the space occupied by the tab in the tab bar: from the right edge of the previous tab to the left edge of the next tab.
→ const List<
A constant List of the values in this enum, in order of their declaration.
