# dataset property

Map<String, String> dataset

Allows access to all custom data attributes (data-*) set on this element.

The keys for the map must follow these rules:

- The name must not begin with 'xml'.
- The name cannot contain a semi-colon (';').
- The name cannot contain any capital letters.

Any keys from markup will be converted to camel-cased keys in the map.

For example, HTML specified as:

    <div data-my-random-value='value'></div>

Would be accessed in Dart as:

    var value = element.dataset['myRandomValue'];

      final data = this.dataset;
      data.clear();
      for (String key in value.keys) {
        data[key] = value[key];
      }
