Error in step code packages #15

Closed fredgrott closed 3 years ago

First the error output when I run goldens update:

PS D:\fredgrttsstuff\GithubProjects\flutter_test\expert_test_setup> the rep where the expert-est-setup project is at is https://github.com/fredgrott/flutter_test I did look at both: https://github.com/olexale/bdd_widget_test/blob/master/lib/step/i_tap_icon.dart and https://github.com/olexale/bdd_widget_test/blob/master/lib/step/i_see_text.dart things that might stand out: one has a missing wait in async block and let's see on null saefy String and IconData fields should they have late modfiers? The error report does not mentioned nUll os it might not be that. Any thoughts on what it might be?

Hi @fredgrott,

Thanks for this ticket!

await is missing in i_see_text by design as there is no asynchronous operation in this step.

It seems like you're testing the default counter app, have you watched this video? If yes - could you please share the app so I could take a look?

Regards, Oleksandr

Hi Fred,

I've tried to compile expert-test-setup project from https://github.com/fredgrott/flutter_test but it fails to compile with the following error:

Have you fixed your problem? Is there anything I can help you with?

Hi Fred,

I hope you already fixed the problem hence I'm closing the issue. Feel free to reopen the ticket if the problem is still there.

Best, Oleksandr
