decodeListTileThemeData static method

ListTileThemeData? decodeListTileThemeData(dynamic value, { bool validate = true, })

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

{
  "contentPadding": "<EdgeInsetsGeometry>",
  "dense": "<bool>",
  "enableFeedback": "<bool>",
  "horizontalTitleGap": "<double>",
  "iconColor": "<Color>",
  "minLeadingWidth": "<double>",
  "minVerticalPadding": "<double>",
  "mouseCursor": "<MaterialStateProperty<MouseCursor>>",
  "selectedColor": "<Color>",
  "selectedTileColor": "<Color>",
  "shape": "<ShapeBorder>",
  "style": "<ListTileStyle>",
  "textColor": "<Color>",
  "tileColor": "<Color>",
  "visualDensity": "<VisualDensity>"
}

Implementation

static ListTileThemeData? decodeListTileThemeData(
  dynamic value, {
  bool validate = true,

  ListTileThemeData? result;

  if (value is ListTileThemeData) {
    result = value;
  } else if (value != null) {
    assert(SchemaValidator.validate(
      schemaId: '$_baseSchemaUrl/list_tile_theme_data',
      value: value,
      validate: validate,
    ));

    result = ListTileThemeData(
      contentPadding: decodeEdgeInsetsGeometry(
        value['contentPadding'],
        validate: false,
      ),
      dense:
          value['dense'] == null ? null : JsonClass.parseBool(value['dense']),
      enableFeedback: value['enableFeedback'] == null
          ? null
          : JsonClass.parseBool(value['enableFeedback']),
      horizontalTitleGap: JsonClass.parseDouble(value['horizontalTitleGap']),
      iconColor: decodeColor(

      textColor: decodeColor(
        value['textColor'],
        validate: false,
