Instead of using alternate package you can directly add flutter_math_fork into your pubspec.yaml and it works fine :)

Following are steps to add package.

add following code in pubspec.yaml

dependencies:
  flutter:
    sdk: flutter
  flutter_html: any
  flutter_math_fork: ^0.7.2

run command

flutter pub get

Had this error after upgrading to Flutter 3.10.0. Fixed it by removing flutter_html and adding it again through flutter pub add flutter_html.

After upgrading to Flutter 3.10.0, there is a new version of flutter_html created especially for this version. At this moment it's flutter_html: ^3.0.0-beta.1

I equally a flutter pub get pinput to get the preferred version of that package cause I realized it was part of the things making the build to crash

flutter pub add pinput

Updating flutter_html to prerelease worked for me:

flutter_html: ^3.0.0-alpha.6

Since the flutter_math_fork is not a package that I use directly. I had to find the issue by running flutter pub deps to see the dependancy graph and find the usage of the package. Then I realised that It is a dependancy of flutter_html then I tried to update the version of flutter_math_fork as well as flutter_html but it wasn't success. So I removed that package and used the following package flutter_widget_from_html as an alternative to the flutter_html then the problem solved.
