VxAppBar constructor

VxAppBar({
  1. Key? key,
  2. Widget? leading,
  3. bool automaticallyImplyLeading = true,
  4. Widget? title,
  5. List<Widget>? actions,
  6. Widget? flexibleSpace,
  7. PreferredSizeWidget? bottom,
  8. double? elevation,
  9. ShapeBorder? shape,
  10. Color? backgroundColor,
  11. Brightness? brightness,
  12. IconThemeData? iconTheme,
  13. IconThemeData? actionsIconTheme,
  14. TextTheme? textTheme,
  15. bool primary = true,
  16. bool? centerTitle,
  17. double titleSpacing = NavigationToolbar.kMiddleSpacing,
  18. double toolbarOpacity = 1.0,
  19. double bottomOpacity = 1.0,
  20. bool searchBar = false,
  21. String searchHintText = 'Search here...',
  22. TextStyle searchHintStyle = const TextStyle(color: Colors.white, fontSize: 14),
  23. TextStyle searchTextStyle = const TextStyle(color: Colors.white),
  24. Color searchBarColorTheme = Colors.white,
  25. TextEditingController? searchController,
  26. GestureTapCallback? onTap,
  27. ValueChanged<String>? onChanged,
  28. ValueChanged<String>? onSubmitted,
})

Creates a material design app bar.

The arguments primary, toolbarOpacity, bottomOpacity and automaticallyImplyLeading must not be null. Additionally, if elevation is specified, it must be non-negative.

If backgroundColor, elevation, brightness, iconTheme, actionsIconTheme, or textTheme are null, then their VxAppBarTheme values will be used. If the corresponding VxAppBarTheme property is null, then the default specified in the property's documentation will be used.

Typically used in the Scaffold.appBar property.
