getWidgetDescription method

  1. @experimental
Future<WidgetDescriptionResult> getWidgetDescription(
  1. String? file,
  2. int? offset
)

Return the description of the widget instance at the given location.

@experimental
Future<WidgetDescriptionResult> getWidgetDescription(
    String? file, int? offset) {
  final Map m = {'file': file, 'offset': offset};
  return _call('flutter.getWidgetDescription', m)
      .then(WidgetDescriptionResult.parse);
}
