decodeExpansionTileThemeData static method

ExpansionTileThemeData? decodeExpansionTileThemeData(dynamic value, { bool validate = true, })

Decodes the given value to an ExpansionTileThemeData. This expects the given value to be of the following structure:

{
  "backgroundColor": "<Color>",
  "childrenPadding": "<EdgeInsetsGeometry>",
  "clipBehavior": "<Color>",
  "collapsedBackgroundColor": "<Color>",
  "collapsedIconColor": "<Color>",
  "collapsedShape": "<ShapeBorder>",
  "collapsedTextColor": "<Color>",
  "expandedAlignment": "<AlignmentGeometry>",
  "iconColor": "<Color>",
  "shape": "<ShapeBorder>",
  "textColor": "<Color>",
  "tilePadding": "<EdgeInsetsGeometry>"
}
