attribute method

void attribute(
  1. String name,
  2. Object value, {
  3. String? namespace,
  4. XmlAttributeType? attributeType,
})

Adds a XmlAttribute node with the provided name and value.

If a namespace URI is provided, the prefix is looked up, verified and combined with the given attribute name.

To generate an element with the tag message and the attribute lang="en" one would write:

builder.element('message', nest: () {
   builder.attribute('lang', 'en');
});

Implementation

void attribute(String name, Object value,
    {String? namespace, XmlAttributeType? attributeType}) {
  final attribute = XmlAttribute(_buildName(name, namespace),
      value.toString(), attributeType ?? XmlAttributeType.DOUBLE_QUOTE);
  _stack.last.attributes.add(attribute);
}
