Load TTF variable font from Compose Multiplatform

Make loading differently weighted fonts from one .ttf file easier. Hopefully this will be supported in Compose Multiplatform natively sometime in the future.

1. Put a single variable .ttf font file in composeResources/font.
2. val fontFamily by loadFont(Res.font.your_font, FontWeight(500))
3. Text("The quick brown fox jumps over the lazy dog", fontFamily = fontFamily)

Supported platforms

• JVM
• Android

Usage

val commonMain by getting {
  dependencies {
    implementation("com.dshatz.compose-mpp:compose-font:<version>")
  }
}

Implementation notes

JVM

On JVM, jetbrains skia api is used.

Android

On Android, the font will be written to app filesDir once and then loaded into memory and copied with variationSettings whenever the fontWeight changes. Unfortunately there is no way to directly load a font on android from composeResources/ folder while also applying variationSettings.
