fixes #456
The problem
The BackStack and the
Controller.resume_main_flow
can create some confusing debugging when an error happens mid-flow.In this case it was:
That would route you to the ErrorView which would then take you BACK, which routes you to SeedOptionsView. That detected the
Controller.resume_main_flow
which then routes toSeedSignMessageConfirmMessageView
which assumes by that point that all necessary data has been loaded, yielding a second error screen.The fix
Don't attempt any kind of resumption of flow when an invalid QR is scanned. Just clear and reset the state (
Controller.resume_main_flow = None
), show ErrorView, and return to the MainMenuView.This PR adds the above change and a matching new test for that flow.
