Updated to canary 13 with alpha04 and found that my imports for Modifiers need a package change from :

import androidx.compose.foundation.layout.RowScope.weight

to

import androidx.compose.foundation.layout.RowScope.Companion.weight

this was discussed here just yesterday

I'll look, my apologies

These are not meant to be statically imported at all; expect this to change again such that the latter doesn't work either. 🙂 If you are using these modifiers directly in a Row or Column, they are already available and do not need to be imported. If you are using them at the top level of an unrelated composable function, you should declare that function as an extension of RowScope or ColumnScope, which will enforce that they must be used inside a Row or Column and also make the child modifiers available

Much appreciated on the response + explanation. I was using

LazyColumnFor()

and my

weight

modifier went red. Got it all sorted with your helps thanks again

Ah, then yes, chances are it wasn't doing anything for you there anyway 🙂
