Support Flutter v3.7

[zaynetro]

Copied the changes from similar changes in simplistic editor. Link points to a specific file. It might take a while to download the diffs though.

Tried example app on Android, Mac and iOS.

Thanks!
Can you also update https://github.com/fleather-editor/fleather/blob/master/.github/workflows/fleather.yml with Flutter 3.7?

'ToolbarOptions' is deprecated and shouldn't be used. Use contextMenuBuilder instead. This feature was deprecated after v3.3.0-0.5.pre

I will check if I can refactor it quickly.

Seems like TextSelectionOverlay should be used instead of custom OverlayEntry? _toolbar in EditorTextSelectionOverlay. It means though quite a few changes :/

Let me know how we can proceed. Luckily, deprecated ToolbarOptions still works.

Arrow keys and backspace buttons do not work on Mac when running example app on Mac...

[zaynetro]

Looks like arrows and backspace are reported in performSelector now.

flutter: performSelector deleteBackward:
flutter: performSelector moveLeft:
flutter: performSelector moveRight:

[zaynetro]

OK. Found what Flutter does internally, copied it and things started to work again.

Thanks for your PR. I'll try to review it in the next few days. @zaynetro

[Amir-P]

LGTM. Just fix the 4 unnecessary_non_null_assertion warnings. Also let's keep ToolbarOptions for now. I think it's better to address it in another PR. @zaynetro
Do you have anything to add @amantoux ?

[zaynetro]

Removed.

[amantoux]

Would you mind ignoring deprecation messages so as to have a green CI?
Otherwise, all good on my end
