So, here is an example of setting the default font-family in M3:
```kotlin
// Type.kt
import androidx.compose.material3.Typography
import androidx.compose.ui.text.font.Font
import androidx.compose.ui.text.font.FontFamily
import androidx.compose.ui.text.font.FontStyle
import androidx.compose.ui.text.font.FontWeight
import com.example.exampleapp.R
// Declare the font families
object AppFont {
val TitilliumWeb = FontFamily(
Font(R.font.titillium_web_regular),
Font(R.font.titillium_web_italic, style = FontStyle.Italic),
Font(R.font.titillium_web_medium, FontWeight.Medium),
Font(R.font.titillium_web_medium_italic, FontWeight.Medium, style = FontStyle.Italic),
Font(R.font.titillium_web_bold, FontWeight.Bold),
Font(R.font.titillium_web_bold_italic, FontWeight.Bold, style = FontStyle.Italic)
)
}
private val defaultTypography = Typography()
val Typography = Typography(
displayLarge = defaultTypography.displayLarge.copy(fontFamily = AppFont.TitilliumWeb),
displayMedium = defaultTypography.displayMedium.copy(fontFamily = AppFont.TitilliumWeb),
displaySmall = defaultTypography.displaySmall.copy(fontFamily = AppFont.TitilliumWeb),
headlineLarge = defaultTypography.headlineLarge.copy(fontFamily = AppFont.TitilliumWeb),
headlineMedium = defaultTypography.headlineMedium.copy(fontFamily = AppFont.TitilliumWeb),
headlineSmall = defaultTypography.headlineSmall.copy(fontFamily = AppFont.TitilliumWeb),
titleLarge = defaultTypography.titleLarge.copy(fontFamily = AppFont.TitilliumWeb),
titleMedium = defaultTypography.titleMedium.copy(fontFamily = AppFont.TitilliumWeb),
titleSmall = defaultTypography.titleSmall.copy(fontFamily = AppFont.TitilliumWeb),
bodyLarge = defaultTypography.bodyLarge.copy(fontFamily = AppFont.TitilliumWeb),
bodyMedium = defaultTypography.bodyMedium.copy(fontFamily = AppFont.TitilliumWeb),
bodySmall = defaultTypography.bodySmall.copy(fontFamily = AppFont.TitilliumWeb),
labelLarge = defaultTypography.labelLarge.copy(fontFamily = AppFont.TitilliumWeb),
labelMedium = defaultTypography.labelMedium.copy(fontFamily = AppFont.TitilliumWeb),
labelSmall = defaultTypography.labelSmall.copy(fontFamily = AppFont.TitilliumWeb)
)
```
```kotlin
// Theme.kt
import androidx.compose.material3.MaterialTheme
import androidx.compose.runtime.Composable
@Composable
fun AppTheme(
content: @Composable () -> Unit
) {
MaterialTheme(
typography = Typography,
content = content
)
}
```
Example for an individual component:
```kotlin
import androidx.compose.material3.Text
import androidx.compose.runtime.Composable
import com.example.exampleapp.theme.AppFont
@Composable
fun ExampleScreen() {
Text(
text = "Hello World!",
fontFamily = AppFont.TitilliumWeb
)
}
```
