Is there something like weight sum for Row or Column

Question

Grigorii Yurkov · Answer

Out of curiosity why do you need it

Se7eN · Answer

For grids where the items in each row can vary

Se7eN · Answer

Something like this ```Column rows forEach rowItems gt Row rowItems forEach item Modifier weight 1f ```

Grigorii Yurkov · Answer

And `rowItems` in each row has different size

Se7eN · Answer

Yep

Adam Powell · Answer

You can approximate it by optionally including a Box with a weight of `targetWeight rowItems size` if the value of that expression is gt 0

Grigorii Yurkov · Answer

I think `Spacer` is better if I get you correctly

Se7eN · Answer

Yeah I m drawing boxes right now Just wanted to know if there was weight sum Thanks

Se7eN · Answer

Spacer could be better but it doesn t really matter since it s not a significant difference

Grigorii Yurkov · Answer

Yeah and you can also hammer in nails with a microscope slightly smiling face

Se7eN · Answer

We can hammer in nails with glasses on off smile

Se7eN · Answer

I had nulls in the list before to indicate empty positions but I trying Adam s approach and getting this weird error

The code is ```val rows = items chunked numColumns Column modifier rows forEach items gt Row horizontalArrangement = Arrangement spacedBy 16 dp Alignment CenterHorizontally items forEach itemContent Modifier weight 1f val weight = numColumns items size if weight gt 0 Spacer Modifier weight weight toFloat ```

Looks like a compiler problem
