getSemanticsId method Null safety
- SerializableFinder finder,
- {Duration? timeout}
Retrieves the semantics node id for the object returned by finder
, or
the nearest ancestor with a semantics node.
Throws an error if finder
returns multiple elements or a semantics
node is not found.
Semantics must be enabled to use this method, either using a platform specific shell command or setSemantics.
Implementation
Future<int> getSemanticsId(SerializableFinder finder, { Duration? timeout }) async {
final Map<String, dynamic> jsonResponse = await sendCommand(GetSemanticsId(finder, timeout: timeout));
final GetSemanticsIdResult result = GetSemanticsIdResult.fromJson(jsonResponse);
return result.id;
}
