Hi, I had a question regarding default value for `...

Hi, I had a question regarding default value for Modifier as a parameter, apparently fillMaxWidth is ignored if passed like this.

@Composable
fun TextButton(
    modifier: Modifier = Modifier.fillMaxWidth(),

[wck]

yeah, that’s the way to go, thanks.

Or just modifier.fillMaxWidth()

This is perfectly idiomatic and is used throughout the Compose codebase.

yep. convention is to have the default expression just be modifier: Modifier = Modifier and then just start your modifier chain with that:

InternalTextButton(modifier = modifier.fillMaxWidth().etc(...)

note that the documents saying the first modifier parameter must: … are indicating what the convention is, not what is technically allowed/not allowed. what you wrote initially was perfectly valid kotlin, just not what you wanted 🙂

Oh, I guess I'll add it to the detekt-rules-compose as a new (togglable) rule.

UPD: turns out there was already an issue-request for such a rule
