Description

This rule mandates that function names in Kotlin should be written in camel case, starting with a lowercase letter using no underscores.

The exceptions are factory functions, which may be named the same as the type they create, and @Composable functions, which must still be in camel case, but starting with a capital letter.

Non-Compliant Code Examples

fun Foo() {}

fun Foo_Bar() {}

fun `Foo Bar`() {}

fun foo_bar() {}

Compliant Code Examples

fun foo() {}

fun fooBar() {}

fun `fun`() {} 

// Factory functions can have the same name as the type they create
fun MyService(): MyService {}

// Composable functions are in CamelCase
@Composable
fun MyButton(text: String) {}
