FocusTargetNode

Retained capability that makes its logical component a keyboard and text-input focus target.

requestsInitialFocus

open val requestsInitialFocus: Boolean

Whether this node requests focus when no retained component currently owns it after layout.

requiresTextInput

open val requiresTextInput: Boolean

Whether this accepting focus target edits text and requires the platform's text-input mode.

Functions
