fix: new lints after flutter upgrade

[tom-anders]

These new lints block all other PRs currently, but they're straight-forward to fix

sorry for spaming PRs while you're gone 😬

Seems like letsar/flutter_slidable#484 breaks the build still

Huh, so with flutter 3.25 (and after fixing the flutter_slideable error as described in the linked issue) the app now consistently freezes and then crashes my Android emulator after making a move on the analysis board - Downgrading back to flutter 3.24 fixed this, not sure what's going on here. Might (hopefully) be a local issue.

Setting up a new emulator from scratch solved this, probably a local issue indeed (I use arch btw)

@tom-anders not sure why but tests are failing here.
