Crash when updating to latest compose bom 2025.09.01

[kikin81]

When updating projects to the Compose BOM 2025.09.01, Showkase crashes on launch.

This is due to the Compose Material library moving the Icons set into a separate Gradle dependency starting in newer BOM versions.

Workaround

Projects can add the separate dependency to their app module:

// In gradle/libs.versions.toml
androidx-compose-material-icons-extended = { group = "androidx.compose.material", name = "material-icons-extended" }

// In app/build.gradle.kts
dependencies {
    implementation(libs.androidx.compose.material.icons.extended)
}

Proposed Fix

Showkase should include the material-icons dependency itself (or at least material-icons-core) to prevent this crash, since the library relies on Material Icons for
its UI.

Environment

• Showkase version: 1.0.5
• Compose BOM: 2025.09.01
• Android Gradle Plugin: 8.13.0
