object Converter {
     
    @JvmStatic
    @BindingConversion
    @InverseMethod("convertToDouble")
    public fun convertToString(d: Double?): String {
        return d?.toString() ?: ""
    }

    @JvmStatic
    @BindingConversion
    public fun convertToDouble(d: String?): Double? {
        return d?.toDouble()
    }
}

When I am trying to use converter

android:text="@={Converter.convertToString(viewModel.feeIncomeTaxPercentage)}"

I am getting compilation errror
