To clear focus from the currently focused component you can use the FocusManager.clearFocus method:
val focusRequester = remember { FocusRequester() }
val focusManager = LocalFocusManager.current
var value by rememberSaveable { mutableStateOf("initial value") }
BasicTextField(
value = value,
onValueChange = { value = it },
decorationBox = { innerTextField ->
Row(
Modifier
.background(Color.LightGray, RoundedCornerShape(percent = 30))
.padding(16.dp)
.focusRequester(focusRequester)
) {
//...
innerTextField()
}
}
)
Button(onClick = { focusManager.clearFocus() }) {
Text("Clear focus")
}
