decodeDataTableThemeData static method

DataTableThemeData? decodeDataTableThemeData(dynamic value, { bool validate = true, })

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

{
  "columnSpacing": <double>,
  "dataRowColor": <MaterialStateProperty<Color>>,
  "dataRowHeight": <double>,
  "dataTextStyle": <TextStyle,
  "dividerThickness": <double>,
  "headingRowColor": <MaterialStateProperty<Color>>,
  "headingRowHeight": <double>,
  "headingTextStyle": <TextStyle>,
  "horizontalMargin": <double>
}

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

Implementation

static DataTableThemeData? decodeDataTableThemeData(
  dynamic value, {
  bool validate = true,
}) {
  DataTableThemeData? result;

  if (value is DataTableThemeData) {
    result = value;
  } else if (value != null) {
    assert(SchemaValidator.validate(
      schemaId: '$_baseSchemaUrl/data_table_theme_data',
      value: value,
      validate: validate,
    ));
    result = DataTableThemeData(
      columnSpacing: JsonClass.parseDouble(
        value['columnSpacing'],
      ),
      dataRowColor: decodeMaterialStatePropertyColor(
        value['dataRowColor'],
        validate: false,
      ),
      dataRowHeight: JsonClass.parseDouble(
        value['dataRowHeight'],
      ),
      dataTextStyle: decodeTextStyle(
        value['dataTextStyle'],
        validate: false,
      ),
      dividerThickness: JsonClass.parseDouble(
        value['dividerThickness'],
      ),
      headingRowColor: decodeMaterialStatePropertyColor(
        value['headingRowColor'],
        validate: false,
      ),
      headingRowHeight: JsonClass.parseDouble(
        value['headingRowHeight'],
      ),
      headingTextStyle: decodeTextStyle(
        value['headingTextStyle'],
        validate: false,
      ),
      horizontalMargin: JsonClass.parseDouble(
        value['horizontalMargin'],
      ),
    );
  }

  return result;
