ComposeDestinations 带参数返回

ComposeDestinations

发起方 XXX

通过使用ResultRecipient参数来实现注册回调监听。

@Destination
@Composable
fun XXX(
    navigator: DestinationsNavigator = EmptyDestinationsNavigator,
    result: ResultRecipient<YYYDestination, String> = EmptyResultRecipient(),
) {
    result.onNavResult {
        EchoLog.log("resultRecipient", it)
        when (it) {
            is NavResult.Canceled -> {}
            is NavResult.Value -> { 
                       //----
                 }
            }
        }
    }

返回方YYY

通过ResultBackNavigator来实现数据回传

@Destination
@Composable
fun YYY(
    navigator: DestinationsNavigator = EmptyDestinationsNavigator,
    resultBackNavigator: ResultBackNavigator<String> = EmptyResultBackNavigator()
) {
  //在需要返回的地方
  resultBackNavigator.navigateBack("ans")
}
