Move cursor using pointer input

[TylerAtCodeOfLife]

Feature description

Your documentation and examples have no examples where you can touch the input. How difficult would this be to implement with your underlying widgets?

Thanks for the question @TylerAtCodeOfLife 🙏

Could you elaborate on what exactly you are thinking about? It might also be beneficial to change the issue title to something more descriptive when doing that. I have some guesses on what you mean by "touch the input", however, I am not sure I understand you correctly.

Didn't realize how vague I was being.

I meant that on your examples I was able to move the cursor with arrow keys provided, but touching the input box did not move the cursor.

I'm asking because I've created interfaces like this before and while the example page shows that your keypad and input field are working the example didn't let me touch where i wanted to edit to move the cursor and it also didn't let me select part of an equation.

I wanted to ask before digging into your code because I thought you'd have to use https://api.flutter.dev/flutter/rendering/RenderEditable-class.html
but you don't mention it

Thanks @TylerAtCodeOfLife - it makes sense :)

This is not yet built-in. This is something that @znjameswu put some effort into I think (as part of https://github.com/znjameswu/flutter_math). Having said that, flutter_math already has selection support, which is why I think it would not be too hard to add.

I mirrored some of the EditableText behavior, however, did not go with RenderEditable.
