Example project 'stocks' doesn't work #687

Closed lkhorasandzhian closed 1 year ago

lkhorasandzhian commented 1 year ago

Description

I tried to run your 'stocks' project for checking whether my hover had been successfully set up, but I got error below. Then I did the same for another project ('pointer_demo'), and it ran without any error. Maybe I was doing something wrong... Anyway, I'm waiting for your response!

Our demo was build before flutter 2.0, the error you are seeing is related to this, the FlatButton (or the way we import it) might be deprecated. This is an error from the flutter framework that can be fixed by updating our demo Dart code to the new flutter 2.0 frw. I dont have any time at the moment for this, but if you know flutter, and have some, you can easily fix this.
