So i discovered that i get some errors from the pubspec.yaml actually 740 or something like that, i don't know what i did wrong. it seems that everything inside is wrong event though i haven't added anything. I tried removing some code but it makes no difference. I think i added something in the code that's wrong. What could be wrong with this?

It would work fine.
