property dataset


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'];
