decodeTooltipThemeData static method

TooltipThemeData? decodeTooltipThemeData(dynamic value, { bool validate = true, })

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

{
  "enableFeedback": "<bool>",
  "excludeFromSemantics": "<bool>",
  "height": "<double>",
  "margin": "<EdgeInsetsGeometry>",
  "padding": "<EdgeInsetsGeometry>",
  "preferBelow": "<bool>"
  "showDuration": "<int; millis>",
  "textAlign": "<TextAlign>",
  "textStyle": "<TextStyle>",
  "verticalOffset": "<double>",
  "waitDuration": "<int; millis>"
}
