measured with an infinity maximum height 🤖 Android

Jetpack Compose: Vertically scrollable component was measured with an infinity maximum height constraints, which is disallowed

A LazyColumn (or verticalScroll) is placed inside another vertically scrolling container, so it gets infinite height.

Seen on: Android

Meaning

Nested scrolling in the same direction gives the inner list unbounded height. Use one LazyColumn with multiple item blocks, or give the inner list a fixed/weighted height.

Common causes

  • LazyColumn inside Column(Modifier.verticalScroll)
  • LazyColumn inside another LazyColumn item
  • Scrollable inside a parent with wrapContent height in the same direction

⚡ Quick fix

  1. Merge into a single LazyColumn with item {} / items {}
  2. Give the inner list Modifier.height(...) or weight(1f)
  3. Remove the outer verticalScroll

Detailed fix by platform

Kotlin

  1. kotlin
    LazyColumn {
    item { Header() }
    items(users) { UserRow(it) }
    item { Footer() }
}

How to diagnose

  1. Hierarchy — Parent scroll containers
  2. Modifiers — Height constraints
