Dependency version mismatch？

[linchangyi]

Hey, I am new to contributing to open source. I am trying to setup the project.
I have cloned the projects and followed the steps mentioned in https://docs.appflowy.io/docs/documentation/appflowy/from-source/environment-setup/building-on-macos
I have completed step 3. But on step 4, when building the flutter app, I got this

The issue arises because the package flutter_math_fork: ^0.7.3 depends on RenderObjectWithLayoutCallbackMixin, which is not available in Flutter version 3.27.4. After investigation, I found that the RenderObjectWithLayoutCallbackMixin exists in Flutter version 3.32.4.

I want to confirm whether the project has been updated to a version newer than Flutter 3.27.4. If not, how can I resolve the issue of RenderObjectWithLayoutCallbackMixin not being found?
