Bug description

The package seems to be incompatible with Flutter SVG, as the dependency for petitparser is out of date, set to ^4.0.2

To Reproduce

Steps to reproduce the behaviour:

1. Install math_keyboard
2. Install flutter_svg
3. Try to run app and observe error

Expected behavior

For both packages to work together

Error Log

Because math_keyboard >=0.0.1 depends on petitparser ^4.0.2 and xml >=5.4.0 depends on petitparser ^5.0.0, math_keyboard >=0.0.1 is incompatible with xml >=5.4.0.
And because flutter_svg 1.1.1+1 depends on xml ^6.0.1 and no versions of flutter_svg match >1.1.1+1 <2.0.0, math_keyboard >=0.0.1 is incompatible with flutter_svg ^1.1.1+1.
So, because app_name depends on both flutter_svg ^1.1.1+1 and math_keyboard ^0.1.6, version solving failed.
pub get failed (1; So, because app_name depends on both flutter_svg ^1.1.1+1 and math_keyboard ^0.1.6, version solving failed.)

Description

• Use an updated version of flutter_math_fork 0.6.2 that introduces CursorNode and \cursor function
• Replace Cursor implementation via | symbol with \cursor
• Updated empty field offset dx from -4 to -1, since \cursor has smaller horizontal paddings

Bug description

When trying to add fractions into the mathtextfield they end up giving a parser error after trying to edit

To Reproduce

Steps to reproduce the behavior: _mathController.addLeaf(r"\frac{1"); _mathController.addLeaf("2"); _mathController.addLeaf("}{3"); _mathController.addLeaf("4"); _mathController.addLeaf("}"); _mathController.addLeaf("");

try editing the fraction using the math keyboard.

Expected behavior

It would be great if you could add fractions into the mathfield by using addLeaf(). Maybe I'm just not looking in the right places for this functionality.

"Parser Error: Expected '}', got 'EOF' makes sense since I'm deleting the bracket, but how do I make the fraction editable in the mathtextfield?

Hello and thank you first of all that you have put so much effort into the package and make it available to us.

Actually everything works very well, I only have a single problem. To help you understand the problem, maybe I should briefly describe my situation: I am currently working on a math app and get a LaTeX string result, which I would like to edit with your package. So as soon as a MathField is created, I want to give it a MathFieldEditingController and change the value with mathFieldEditingController.updateValue('...'); with my LaTeX value when initializing the class. This all works very well, if I take the examples from your or the math_expressions package.

But if I want to take the LaTeX string from me and convert it to an expression I always get an error. I tried it with the TeXParser('...').parse();, as well as the Expression expression = parser.parse('...'); method. I also tried several times to transform the string somehow so that the expression can be created, however it did not work.

Of course it could be that I don't understand the method somehow, but can someone help me and tell me how to put the LaTeX string from me into your MathField?

Here you also have a few examples with the values and the exceptions that occurred, so that you understand even better what exactly I mean:

When I was writing, using normal parentheses, if I entered internal fractions, the parenthesis was visibly small and not beautiful.

So I tried to change the normal parenthesis to \left or \right, but each needs the other, and when the user writes the expression starting with opening the parenthesis '\left(' the system fails because it does not find the \right.

So I tried to create a button for myself, in order to create both the \left (and the \right) and let the user type in between. However, I'm not sure how to set it up, I've tried several cases but I don't understand how to do it or if it's possible.

Bug description

node.buildTeXString() seems to have a cursorColor property, but it really shouldn't need one. All it does is append something like \textcolor{#000000}{\cursor} to the end of tex string, and it seems to break loading it back into the MathField document

To Reproduce

Steps to reproduce the behavior: Get a MathFieldEditingController and call .currentNode.buildTexString() and try to load the string back in

Expected behavior

No cursorColor attribute, loading back in without changes
