Component used: ProtoLayout Material Version used: 1.4.0-alpha04

The docs for PrimaryLayout.setContent describe the constraints on the content.

https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:wear/protolayout/protolayout-material/src/main/java/androidx/wear/protolayout/material/layouts/PrimaryLayout.java;l=263?q=PrimaryLayout

         * <p>The content slot will wrap the elements' height, so the height of the given content
         * must be fixed or set to wrap ({@code expand} can't be used).
         *
         * <p>This layout has built-in horizontal margins, so the given content should have width
         * set to {@code expand} to use all the available space, rather than an explicit width which
         * may lead to clipping.

But I didn't notice it the first time, and had to read it a second time. My content just didn't show.

Could the lint check flag these when the content is inline?

Perhaps also consider making a warning, or failure in debug/preview mode?
