The longPress method has been added to the WidgetTester class

FlutterDriver doesn't seem to have this method out of the box.

A workaround is to scroll with a 0 delta. That will lead the driver to do what effectively is a long press.

await driver.scroll(target, 0, 0, Duration(milliseconds: 400));

thank you for your answer, unfortunately driver is a FlutterDriver and there is no longPress or is there a way to create the WidgetTester for integration test? – Thomas Frick Feb 05 '19 at 06:11
Would you mind sharing a bit more of your code? The widget tester should be available inside your test methods. – Edman Feb 05 '19 at 07:19
@ThomasFrick I dug around a bit and updated my answer. – Edman Feb 05 '19 at 08:11
@ThomasFrick FlutterDriver is pretty dumb. It's for runtime testing and performance profiling. WidgetTester is for instant testing in your IDE, without deploying a real build into your device, and it has much more capabillities. – Sergey Molchanovsky Jun 21 '20 at 20:03
As of Flutter 2 you can now long press. Look at the answer underneath – joshpetit Oct 13 '21 at 10:43
