QUESTION
I have a Flow that wraps a sealed class, which is used for calling messages to the UI. For example to show a Snackbar. I can observe the Flow from a Composable using LaunchedEffect. But the problem is that I want to retrieve the string resources from the coroutine scope. And I don't want to use direct string value in my view model, since I want to use the Locale for different languages so I pass the String Res Id instead. So is there a good way of doing it without putting the string resources in the Application class and retrieving them from there as sujested here getString Outside of a Context or Activity
The code below:
- I have Scaffold for showing snackbar, when the user clicks the scaffold which fills the whole screen the showSnackbarWithScope method is called, which emits new value to the Flow.
- Then the change is catch through the LaunchedEffect
- Then it calls the showSnackbar() method with the message, but the function expects String and I have String Res Id (Int) value
- The problem I cannot use stringResource() method which retrieves the string from Composable scope, since I am in a coroutine

in any composable using LocalContext
and then use it inside LaunchedEffect
to get your resources:
QUESTION
I've made a queue, which contains tasks to do. After creating some tasks manually with new Task()
in Returns
method, my whole application hangs - await current;
. The body of the task is not even triggered.
ConfigureAwait(false)
didn't help.
The first task in the queue, which is not created by me, but other framework is executing successfully and returning a value. Mine - doesn't. I've tried add Task.CompletedTask
and then it has worked. I don't understand why I can't even reach the body of the task containing _output
assignment.
---UPDATE---
The code works when I use code below. With await
it doesn't. Any ideas?
ANSWER
Answered 2020-Feb-13 at 02:52You should never use the Task
constructor. This goes double on ASP.NET, since constructed tasks are always Delegate Tasks, which interfere with the ASP.NET usage of the thread pool. The actual reason that the await
hangs is because manually-created tasks need to be started.
If you have synchronous work that you need to wrap into a Task
to work alongside asynchronous tasks, then you should use Task.CompletedTask
and Task.FromException
:
QUESTION
I am trying to use EventSource with Microsoft.Diagnostics.EventFlow and I cannot make it output to the console. Here is an example where it works with Inputs.Trace but does not work with Inputs.EventSource:
myEventFLowConfig.json:
...ANSWER
Answered 2020-Jan-22 at 08:15I found the problem, and that was the configuration file. The sources part should go inside of the inputs part. So, there should be only inputs and outputs collection in the configuration file. The working configuration for the EventSource as the input, and StdOutput as output looks like this:
