decodeBottomNavigationBarThemeData static method

BottomNavigationBarThemeData? decodeBottomNavigationBarThemeData(dynamic value, { bool validate = true, })

Decodes the given value to an BottomNavigationBarThemeData. This expects the given value to follow the structure below:

{
  "backgroundColor": "<Color>",
  "elevation": "<double>",
  "enableFeedback": "<bool>",
  "landscapeLayout": "<BottomNavigationBarLandscapeLayout>",
  "mouseCursor": "<WidgetStateProperty<MouseCursor>>",
  "selectedIconTheme": "<IconThemeData>",
  "selectedIconColor": "<Color>",
  "selectedLabelStyle": "<TextStyle>",
  "showSelectedLabels": "<bool>",
  "showUnselectedLabels": "<bool>",
  "type": "<BottomNavigationBarType>",
  "unselectedIconTheme": "<IconThemeData>",
  "unselectedItemColor": "<Color>",
  "unselectedLabelStyle": "<TextStyle>",
}
