focusRestorer

Compose Modifier

Common
fun Modifier.focusRestorer(fallback: FocusRequester = Default): Modifier

This modifier can be used to save and restore focus to a focus group. When focus leaves the focus group, it stores a reference to the item that was previously focused. Then when focus re-enters this focus group, it restores focus to the previously focused item.

Parameters

fallbackA FocusRequester that is used when focus restoration fails to restore the initially focused item. For example, this might happen if the item is not available to be focused. The default value of FocusRequester.Default chooses the default focusable item.
Common

Deprecated Use focusRestorer(FocusRequester) instead

@ExperimentalComposeUiApi
fun Modifier.focusRestorer(onRestoreFailed: (() -> FocusRequester)?): Modifier

Deprecated focusRestorer API. Use the version accepting FocusRequester instead of the lambda. This method will be removed soon after submitting.
