decodeDatePickerThemeData static method

DatePickerThemeData? decodeDatePickerThemeData(dynamic value, { bool validate = true, })

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

{
  "backgroundColor": "<Color>",
  "cancelButtonStyle": "<ButtonStyle>",
  "confirmButtonStyle": "<ButtonStyle>",
  "dayBackgroundColor": "<WidgetStateProperty<Color>>",
  "dayForegroundColor": "<WidgetStateProperty<Color>>",
  "dayOverlayColor": "<WidgetStateProperty<Color>>",
  "dayStyle": "<TextStyle>",
  "dividerColor": "<Color>",
  "elevation": "<double>",
  "headerBackgroundColor": "<Color>",
  "headerForegroundColor": "<Color>",
  "headerHeadlineStyle": "<TextStyle>",
  "headerHelpStyle": "<TextStyle>",
  "inputDecorationTheme": "<InputDecorationTheme>",
  "rangePickerBackgroundColor": "<Color>",
  "rangePickerElevation": "<double>",
  "rangePickerHeaderBackgroundColor": "<Color>",
  "rangePickerHeaderForegroundColor": "<Color>",
  "rangePickerHeaderHeadlineStyle": "<TextStyle>",
  "rangePickerHeaderHelpStyle": "<TextStyle>",
  "rangePickerShadowColor": "<Color>",
  "rangePickerShape": "<ShapeBorder>",
  "rangePickerSurfaceTintColor": "<Color>",
  "rangeSelectionBackgroundColor": "<Color>",
  "rangeSelectionOverlayColor": "<WidgetStateProperty<Color>>",
  "shadowColor": "<Color>",
  "shape": "<ShapeBorder>",
  "surfaceTintColor": "<Color>",
  "todayBackgroundColor": "<WidgetStateProperty<Color>>",
  "todayBorder": "<ShapeBorder>",
  "todayForegroundColor": "<WidgetStateProperty<Color>>",
  "weekdayStyle": "<TextStyle>",
  "yearBackgroundColor": "<WidgetStateProperty<Color>>",
  "yearForegroundColor": "<WidgetStateProperty<Color>>",
  "yearOverlayColor": "<WidgetStateProperty<Color>>",
  "yearStyle": "<TextStyle>"
}

This will use the properties passed through JSON to create the WidgetStateProperty of each corresponding property by using the WidgetStateProperty.all function with the value passed in.
