how to apply local.properties to project

Project.kt

fun Project.getLocalOrDefaultProperties(): Map<String, Any?> {
    return getEnvOrDefaultProperties("local.properties")
}

private fun Project.getEnvOrDefaultProperties(path: String): Map<String, Any?> {
    return rootProject.file(path)
        .takeIf { it.canRead() }
        ?.let { readProperties(it).toMap() as Map<String, Any?> }
        ?: properties.toMap()
}

private fun Project.readProperties(file: File): Properties {
    return Properties().apply {
        load(FileInputStream(file))
    }
}

// use it via gradle.kts
val envProps = getLocalOrDefaultProperties()
val properties01: String by envProps
val properties02: String by envProps
