decodeButtonThemeData static method

ButtonThemeData? decodeButtonThemeData(dynamic value, { bool validate = true, })

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

{
  "alignedDropdown": "<bool>",
  "buttonColor": "<Color>",
  "colorScheme": "<ColorScheme>",
  "disabledColor": "<Color>",
  "focusColor": "<Color>",
  "height": "<double>",
  "highlightColor": "<Color>",
  "hoverColor": "<Color>",
  "layoutBehavior": "<ButtonBarLayoutBehavior>",
  "materialTapTargetSize": "<MaterialTapTargetSize>",
  "minWidth": "<double>",
  "padding": "<EdgeInsetsGeometry>",
  "shape": "<ShapeBorder>",
  "splashColor": "<Color>",
  "textTheme": "<ButtonTextTheme>"
}
