enableFlutterDriverExtension function

void enableFlutterDriverExtension ({DataHandler handler, bool silenceErrors: false })

Enables Flutter Driver VM service extension.

This extension is required for tests that use package:flutter_driver to drive applications from a separate process.

Call this function prior to running your application, e.g. before you call runApp.

Optionally you can pass a DataHandler callback. It will be called if the test calls FlutterDriver.requestData.

slienceErrors will prevent exceptions from being logged. This is useful for tests where exceptions are expected. Defaults to false. Any errors will still be returned in the response field of the result json along with an isError boolean.

Implementation 

void enableFlutterDriverExtension({ DataHandler handler, bool silenceErrors = false }) {
  assert(WidgetsBinding.instance == null);
  _DriverBinding(handler, silenceErrors);
  assert(WidgetsBinding.instance is _DriverBinding);
}
