Compose FontFamily error: "Variable must be initialized"-CodePudding

I'm trying to add fonts to my app but when I declare the fonts in Type.kt file I get this error saying

Variable 'iranSansFontFamily' must be initialized

Why am I getting this error?

Here's the code:

val CustomTypography = Typography(
    bodyLarge = TextStyle(
        fontFamily = iranSansFontFamily,
        fontWeight = FontWeight.Normal,
        fontSize = 16.sp,
        lineHeight = 24.sp,
        letterSpacing = 0.5.sp
    )
)

val iranSansFontFamily = FontFamily(
    Font(R.font.iransans_farsi_medium, FontWeight.Medium),
    Font(R.font.iransans_farsi_bold, FontWeight.Bold)
)

CodePudding user response：

the declaration of the font family must be on the top of typography, like that:

val iranSansFontFamily = FontFamily(
    Font(R.font.iransans_farsi_medium, FontWeight.Medium),
    Font(R.font.iransans_farsi_bold, FontWeight.Bold)
)

val CustomTypography = Typography(
    bodyLarge = TextStyle(
        fontFamily = iranSansFontFamily,
        fontWeight = FontWeight.Normal,
        fontSize = 16.sp,
        lineHeight = 24.sp,
        letterSpacing = 0.5.sp
    )
)
