requestData method
Sends a string and returns a string.
This enables generic communication between the driver and the application. It's expected that the application has registered a DataHandler callback in enableFlutterDriverExtension that can successfully handle these requests.
Implementation
Future<String> requestData(String? message, {Duration? timeout}) async {
return RequestDataResult.fromJson(
await sendCommand(RequestData(message, timeout: timeout)),
).message;
}
