Flutter_Tex doesn't show any Text

Question

I'm trying to make a math quiz game so to show math equations I use flutter_tex but the only thing that show it my screen is an error and a very thin line here is a picture: the code is very simple this is the code:

ListView(
  children: [TeXView(
              renderingEngine: TeXViewRenderingEngine.katex(),

              child: TeXViewDocument(
                  r"""<h2>\( \rm\\TeXViewTest\) 1 with ripple</h2>""",
                                ),
                            ),
                          ]
                        )

this is the error that I get:

E/InputMethodManager(12646): b/117267690: Failed to get fallback IMM with expected displayId=22 actual IMM#displayId=0 view=io.flutter.plugins.webviewflutter.InputAwareWebView{30d1916 VFEDHVC.. ........ 0,0-848,4}

I have tried the examples from the flutter_tex website but it didn't work as well.

Thank you for your time.
