resolveValues method

Future<List<String>> resolveValues(
  1. List<String> values,
  2. NodeId nodeId, {
  3. String? propertyName,
  4. PseudoType? pseudoType,
  5. String? pseudoIdentifier,
})

Resolve the specified values in the context of the provided element. For example, a value of '1em' is evaluated according to the computed 'font-size' of the element and a value 'calc(1px + 2px)' will be resolved to '3px'. values Substitution functions (var()/env()/attr()) and cascade-dependent keywords (revert/revert-layer) do not work. nodeId Id of the node in whose context the expression is evaluated propertyName Only longhands and custom property names are accepted. pseudoType Pseudo element type, only works for pseudo elements that generate elements in the tree, such as ::before and ::after. pseudoIdentifier Pseudo element custom ident.

Implementation

Future<List<String>> resolveValues(
  List<String> values,
  dom.NodeId nodeId, {
  String? propertyName,
  dom.PseudoType? pseudoType,
  String? pseudoIdentifier,
}) async {
  var result = await _client.send('CSS.resolveValues', {
    'values': [...values],
    'nodeId': nodeId,
    if (propertyName != null) 'propertyName': propertyName,
    if (pseudoType != null) 'pseudoType': pseudoType,
    if (pseudoIdentifier != null) 'pseudoIdentifier': pseudoIdentifier,
  });
  return (result['results'] as List).map((e) => e as String).toList();
}
