Error RoundedButton

[PyrolaMinor]

Hello,

I'm new in Flutter. When I run the App, I have the following error with the RoundedButton on the OnPressed asyn : "Future is not as subtype of type (() =>void)?" . I don't understand this problem :/

Hi there, please share which Flutter version you are using. I need to update the app for current version as some things might be deprecated.
