Bengali Font not rendering well

[RomjanHossain]

All the mathematical expression works fine. but when it comes to Bengali text, it brokes badly. i've tried using GoogleFonts, Local Fonts (assets/fonts/*), but None of them works.

options: MathOptions(
                                fontSize: 11,
                                mathFontOptions: FontOptions(
                                  fontFamily: 'NotoSansBengali',
                                ),
                                textFontOptions: FontOptions(
                                  fontWeight: FontWeight.normal,
                                  fontFamily: 'NotoSansBengali',
)),

Math.tex(
              '\\text{জ্যামিতি সম্পর্কিত} \quad \sum_{n=1}^{\infty} \\frac{1}{n^2} = \\frac{\\pi^2}{6}',
              textStyle: GoogleFonts.notoSansBengali(
                fontSize: 24, // Adjust size as needed
                color: Colors.black,
              ),

              mathStyle: MathStyle.display,
),

Error log:
[Flutter Math] LaTeX-incompatible input and strict mode is set to 'warn': Unicode text character "জ used in math mode" [unicodeTextInMathMode]

when i try to add custom fonts to mathFontOption, it shows:
Build Exception: Unsanitized build exception detected: Exception: Font metrics not found for font: NotoSansBengali-Regular..Pleasae report this error with corresponding input.

code:

mathFontOptions: FontOptions(
                             fontFamily: 'NotoSansBengali',
),
