Support Flutter 3.3

[Amir-P]

Flutter 3.3 again has changes in text editing API and now provides granular text changes (deltas).

@Amir-P is my error in recent Flutter related to delta operations?

The following TypeErrorImpl was thrown while dispatching notifications for FleatherController:
Expected a value of type 'String', but got one of type 'List<Operation>'

When the exception was thrown, this was the stack:

What did you do that caused this issue? Can you provide a reproducible example? Also which version of Fleather you're using? @bkraszewski

[bkraszewski]

@Amir-P I'm on 3.3.5, Flutter web. When I click on the editor, I can not see caret, when I start typing it works as expected but can see the error in the log. Will post extracted code.
Using Chrome 106.0.5249

@Amir-P Today I created a new project to reproduce this issue and everything worked fine - I'll try adding other dependencies I'm using to see if it breaks

Thanks, it would help a lot if you provide an example. Also, which version of Fleather are you using?

@bkraszewski @Amir-P I'm successfully using fleather 1.3.0 on web and linux. It works great. Thank you for this package!
