I have a Gallery. I am creating columns in this Gallery manually.

This basically creates a "repeating table" with n numbers of rows.

How to detect if a field is empty in a Gallery with repeating rows?

I was thinking I could check if a row value is empty by creating a variable that would concatenate all rows and then check if a flag I create exists.

This works perfectly but I wonder if a better solution exists.

if(IsMatch(Concat(
 Gallery3.AllItems,
 If(IsBlank(TextInput_RequiredField.Text),"~flag~")),"~flag~",Contains),"at least one field is blank")

I can then use this as a condition for a validation step.

Can someone think of another way to accomplish this without Concat()?
