LGTM. Any reason for implementing isLiveTextInputAvailable in the platform plugin instead of the text input plugin?

Hi @LongCatIsLooong
In my op

  1. LiveText is a kind of platform ability (just like clipboard).Maybe there are more functions will be added in the future
    (eg:Maybe like recognizing the text in images on iOS16, that is not much related with text input). So Adding it in FlutterTextInputPlugin may be not so appropriate.

  2. Developers may query this value any time even user is not inputing in any textField (So activeView in FlutterTextInputPlugin is nil and we will still create another UITextField to get this value), which is not so elegant.

So I think it is more appropriate to put it in platform plugin.
You can See the framework interface LiveText I wrote in framework PR:
packages/flutter/lib/src/services/live_text.dart
