Hi,
I'm looking for a way to check function names that use backticks.
Specifically, I want to ensure they do not start with an uppercase letter.
It seems the FunctionParameterNaming rule doesn't apply to these functions.

For example:

@Test
fun `Invalid function name`() {
    
}

@Test
fun `valid function name`() {
    
}

Any guidance on this would be appreciated!

You can extend this rule FunctionNaming just change functionPattern to ``?([a-z][a-zA-Z0-9 ]*)`?`
You need to do this in detkt.yml file, documentation

FunctionNaming:
    active: true
    excludes: ['**/androidTest/**', '**/commonTest/**', '**/jvmTest/**', '**/androidUnitTest/**', '**/androidInstrumentedTest/**', '**/jsTest/**', '**/iosTest/**']
    functionPattern: '`?([a-z][a-zA-Z0-9 ]*)`?'
    excludeClassPattern: '$^'

I did this for this test class

class TestClass {

    fun test() {
        println()
    }

    fun Test() {
        println()
    }

    fun `Test function with capital`() {
        println()
    }

    fun `test function with lowercase letter`() {
        println()
    }
}

Rule found two issue
