decodeTabBarTheme static method

TabBarTheme? decodeTabBarTheme(dynamic value, { bool validate = true, })

Decodes the given value to a TabBarTheme. This expects the value to have the following structure:

{
  "dividerColor": "<Color>",
  "dividerHeight": "<double>",
  "indicatorColor": "<Color>",
  "indicatorSize": "<TabBarIndicatorSize>",
  "labelPadding": "<EdgeInsetsGeometry>",
  "labelColor": "<Color>",
  "labelStyle": "<TextStyle>",
  "mouseCursor": "<WidgetStateProperty<MouseCursor>>",
  "overlayColor": "<WidgetStateProperty<Color>>",
  "splashFactory": "<InteractiveInkSplashFactory>",
  "tabAlignment": "<TabAlignment>"
  "unselectedLabelColor": "<Color>",
  "unselectedLabelStyle": "<TextStyle>",
}
