    implementation ("androidx.compose.ui:ui-text-google-fonts:1.6.1")
}

Initialisez GoogleFont.Provider avec les identifiants de Google Fonts

val provider = GoogleFont.Provider(
    providerAuthority = "com.google.android.gms.fonts",
    providerPackage = "com.google.android.gms",
    certificates = R.array.com_google_android_gms_fonts_certs

Définissez un FontFamily

 import androidx.compose.ui.text.googlefonts.GoogleFont
 import androidx.compose.ui.text.font.FontFamily
 import androidx.compose.ui.text.googlefonts.Font
 // ...

val fontName = GoogleFont("Lobster Two")

val fontFamily = FontFamily(
    Font(googleFont = fontName, fontProvider = provider)
)

Vous pouvez interroger d'autres paramètres de police tels que l'épaisseur et le style avec FontWeight et FontStyle respectivement :

 import androidx.compose.ui.text.googlefonts.GoogleFont
 import androidx.compose.ui.text.font.FontFamily
 import androidx.compose.ui.text.googlefonts.Font
 // ...

val fontName = GoogleFont("Lobster Two")

val fontFamily = FontFamily(
    Font(
        googleFont = fontName,
        fontProvider = provider,
        weight = FontWeight.Bold,
        style = FontStyle.Italic
    )
)

Configurez FontFamily à utiliser dans votre fonction composable Text:

Text(
    fontFamily = fontFamily, text = "Hello World!"
)
