[Feature request] Change width of Tab

[schwarda]

Would be great if there will be an option to change the width of Tab by simple argument in the widget. Now there is just text clip what is not good in some cases..

(missing "v" in the end)

You can change the tab width behavior to size the tab to the content:

TabView(
  tabWidthBehavior: TabWidthBehavior.sizeToContent,
  ...
)
