QUESTION
we received a crash on Firebase for a kotlin method:
...ANSWER
Answered 2022-Apr-12 at 11:53Shouldn't the exception be thrown way before getting to the constructor call for DeliveryMethod?
Within Kotlin, it's not possible for a non-null parameter to be given a null value at runtime accidentally (because the code wouldn't have compiled in the first place). However, this can happen if the value is passed from Java. This is why the Kotlin compiler tries to protect you from Java's null unsafety by generating null-checks at the beginning of some methods (with the intrinsic checkNotNullParameter you're seeing fail here).
However, there is no point in doing that in private or suspend methods since they can only be called from Kotlin (usually), and it would add some overhead that might not be acceptable in performance-sensitive code. That is why these checks are only generated for non-suspend public/protected/internal methods (because their goal is to prevent misuse from Java).
This is why, if you manage to call addSingleDMInAd with a null argument, it doesn't fail with this error. That said, it would be interesting to see how you're getting the null here, because usually the checks at the public API surface are enough. Is some reflection or unsafe cast involved here?
EDIT: with the addition of the calling code, this clears up the problem. You're calling a method that takes a List from Java, with a list that contains nulls. Unfortunately Kotlin only checks the parameters themselves (in this case, it checks that the list itself is not null), it doesn't iterate your list to check for nulls inside. This is why it didn't fail at the public API surface in this case.
Also, the way your model is setup is quite strange. It seems the lateinit is lying because depending on which constructor is used, the properties may actually not be set at all. It would be safer to mark them as nullable to account for when users of that class don't set the value of these properties. Doing this, you won't even need all secondary constructors, and you can just use default values:
QUESTION
I have been using github actions for quite sometime but today my deployments started failing. Below is the error from github action logs
...ANSWER
Answered 2022-Mar-16 at 07:01First, this error message is indeed expected on Jan. 11th, 2022.
See "Improving Git protocol security on GitHub".
January 11, 2022 Final brownout.
This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
This will help clients discover any lingering use of older keys or old URLs.
Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.
As noted by Jörg W Mittag:
For GitHub Actions:There was a 4-month warning.
The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".
Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.
The permanent shutdown is not until March 15th.
As in actions/checkout issue 14, you can add as a first step:
QUESTION
I am trying to create a timer app which have multiple countdown timer for different task. Issue, I am facing is that, if I start one timer, and press back button, timer stops. So I want, that timer to run till either it is being paused or timer ends and alerts the user or app is destroyed. Help me how can I do this using Flutter? Any Sample Code Will be Appreciated? Solution will be rewarded
...ANSWER
Answered 2022-Mar-19 at 03:23When you pop back, any "state" in the widget will be destroyed.
There are three kinds of method you can do to prevent "state" being destroyed (or memory release):
- Using static property
- Using state manager by Provider
- Using state manager by static instance
There are still many method to manage your state, but not mention here, see details in this repo
Static propertyStatic property is something like variable outside your class, like:
QUESTION
I have an animated progress bar associated with a countdown timer.
Currently, the animation of the progress bar is discrete.
How do I make it to be continuous without changing other logic in the code?
Also, is it possible to create the timer with requestAnimationFrame (like the way the animated progress bar is created) instead of the current setInterval?

QUESTION
I've been looking to add a simple countdown timer to my script. I found this one that seemed to do the trick and modified it slightly to only display seconds since I don't need anything more than that.
When I run it, it will skip the 2nd second in the countdown. For example, if I ran Start-CountdownTimer -Seconds 10, the output will be (this is split into separate lines for demo purposes since it'll be on the same line):
ANSWER
Answered 2021-Oct-29 at 14:36Well this should be an improvement to your function and also should solve the problem of jumping an extra second back. I personally do not agree with using $host and would use Clear-Host instead so the function is compatible with PowerShell ISE too but you can change that as you please.

QUESTION
Breaking down a simple case on Android to suspend the main thread and perform concurrent processing with coroutines, the following code only prints Launched and runBlocking never completes:
ANSWER
Answered 2021-Aug-11 at 17:54Note: To clear things out, one should not deliberately block the main/UI thread with runBlocking, because while the UI thread get's released inside runBlocking (if it suspends) for its child coroutines, nothing outside the runBlocking gets executed (no draw methods, nothing), which leads to frozen UI for as long as runBlocking is active.
It's probably due to how "immediate" is implemented. It's not just join(), it's
any suspend function, if you call yield() it won't help, and if you call delay()
mainJob will resume only when the delay is done. Basically mainJob will not
resume as long as runBlocking is running, and runBlocking will not finish until
mainJob is done, which is a deadlock by definition.
You can omit specifying Dispatcher.Main.immediate to the mainJob and let it
inherit its context from runBlocking. And if you want to start executing mainJob as soon
as its declared just yield the thread from runBlocking to it.
QUESTION
I am trying to redirect to another website after countdown. The redirect works, however the countdown decrease only one time.
For example: I have set the counter to 5. But when the pop up opens, its shows 4 and doesn't decrease further.
...ANSWER
Answered 2021-Jul-31 at 04:04Basically what your code is doing now is waiting 5 seconds and redirecting, one side effect of it redirecting is it decrements countdown by 1.
What you need to do is decrement the counter, every second until it becomes zero, then on the next tick you want to do the redirect.
We do this by first checking to see what the count down is at. If it is above zero we want to wait for a second, then decrement the counter by one, and check again.
