dataset property
Allows access to all custom data attributes (data-*) set on this element.
Any data attributes in the markup will be converted to camel-cased keys in the map based on these conversion rules.
For example, HTML specified as:
<div data-my-random-value='value'></div>
Would be accessed in Dart as:
var value = element.dataset['myRandomValue'];
