How to remove the left and right Padding of a List in SwiftUI?

Solution 1:

It looks like .listRowInsets doesn't work for rows in a List that is initialised with content.

So this doesn't work:

List(items) { item in
    ItemRow(item: item)
        .listRowInsets(EdgeInsets())
}

But this does:

List {
    ForEach(items) { item in
        ItemRow(item: item)
            .listRowInsets(EdgeInsets())
    }
}

Solution 2:

Seem we can use PlainListStyle for List for iOS 14

List {
    Text("Row")
}
.listStyle(PlainListStyle())

Solution 3:

Use this modifier:

.listRowInsets(EdgeInsets(....))

However, as stated in the documentation, the insets will be applied to the view when inside a list.

Sets the inset to be applied to the view when placed in a list. (emphasis mine)

Using this modifier on the List itself will have no effect on the views inside it. You must use the modifier on the view inside the List for the modifier to have an effect.

Example usage:

List {
    Text("test")
        .listRowInsets(EdgeInsets(top: -20, leading: -20, bottom: -20, trailing: -20))
}

Solution 4:

The modifier was

.listRowInsets(EdgeInsets(......))

Solution 5:

Remove paddings

iOS 14.2, Xcode 12.2

ScrollView {
    LazyVStack {
        ForEach(viewModel.portfolios) { portfolio in
            PortfolioRow(item: portfolio)
        }
    }
}

This gives you complete control over the list (you can also remove separator using this code). Current implementation of List doesn't provide full control and contains some issues.

Note that this is a completely different API. Both List and LazyVStack are lazy containers, but in contrast to List, LazyVStack doesn't reuse cells, which will SIGNIFICANTLY change the performance when rows are more complex views.
