Adopt pkg:flutter_lints 1.0

Note, this change appears to have broken the back button in the titlebar. I'm guessing there was an incorrect non-null field somewhere that I cleaned up.

Tests would really help =)

Wow, thanks for all the work! Might take us a bit to land this, but we'll make sure it gets in.

It seems the back button issue is due to the TitleBar not rebuilding when selectedBook is changed, not really sure why it worked before...

To fix, change line 36 of app_title_bar.dart to:
bool canGoBack = context.select((BooksModel m) => m.currentBook != null);

And then I would remove appModel.canPopNav as it's not used anywhere else.

Can you make those tweaks, and then I can land this?

EDIT- Nevermind, I was able to push those fixes to your repo :)
