Google best practices says that gpt.js must be in async mode https://developers.google.com/publisher-ads-audits/reference/audits/async-ad-tags
But async mode stop the render tree once is downloaded, and i think that if we can set up placeholders, it can be much better to use with defer.
Anybody can help me with this doubt?
Many thanks
I like t know if is better to use this
than this
to avoid blocking time in the render tree.

I think this might help.
If you dont, those Memory resources get permanently blocked.
I need to load a small settings file before showing the first screen.
I'm curently using the PathProvider plugin, but all the functions in it are async.
Is there any way to find the application documents directory synchroniously and then use dart:io sync functions on it? Instead of showing a placeholder for infinite decimal of a second.
EDIT: considering the first 2 answers, probably my explaination was really bad. The answers suggested me to still use async code. Problem is, I need the directory before runApp(), and I dont want my void main() to be async, because this ruins any splash animation for sure.
And the PathProvider API is async, as far as I can see, only because it utilizes MethodChannel, which is async, but functions behind it in PathProvider are pretty much synchronious.
What I'm asking is - is there a way, on Android or IOS, to know ApplicationDocumentsDirectory in sync code? Maybe without using platform-specific code at all?
You can use FutureBuilder for the same purpose without having to worry about execution.
It will allow you to do your process in the background and allows you to show a splash screen UI until your specified process is complete and data is ready to use.
Note: Any plugin or code which needs access to the device's native method channel will be async by default, since access of the method channel itself is supposed to be async.
I want to save data to local(just a few data), and I find several package for do that (e.g shared_preferences,secure_storage,sqflite), but all of them are need to use await (Future), if I use these, I have to change my existing codes for wrap in Future, but I just feel that's very troublesome, so I am wondering why all of these are need to use await for save data? or can I use another easy way to do that?
Thanks!
To be clear: It is impossible to have a synchronous system call in flutter.
This is due to an architectural decision: Instead of having the language bridge, Flutter uses two bus (one dart, one native) sending messages to each other.
This is faster than by using a bridge but enforce asynchronous messages.
await as the name suggest wait for some event without stopping following lines of code to execute because that work will take some milliseconds to perform. So, it's a good idea to use await which needs to have async in the function.
There is other way of doing this work without using async-await.
That's then().
So, you go with this without having to add async to your function.
performWork().then((result) {}));
If you do not wish to use await you can call then() on the Future object. Refer this link for more details.
If you are working with Flutter you will definitely have to handle Future's there is no work around it.
I'm writing a major mode for a language and I want to offer completion after '.', or following a keypress. Completions are determined by sending a request to a backgound process using process-send-string and set-process-filter. The returned list of completions is dependent on the background process parsing the current state of the file and being instructed to give completions at that particular point.
I have tried using the popular autocomplete package, but it is really not written with this use case in mind. This is partly because it offers automatic suggetions (i.e. without keypress), which is a nice feature that I don't need. The function that you offer it to call needs to be called synchronously, and emacs process control is asynchronous. I have coded something up along the lines of https://github.com/Golevka/emacs-clang-complete-async, but it doesn't feel robust at all, and has been very fiddly to get it working.
I like the menus used in autocomplete, and would like to know what would fit best with my use-case, preferably while also looking nice.
You can wait synchronously for a background process's output with accept-process-output. You might like to take a look at gud-gdb-completions and gud-gdb-run-command-fetch-lines in a recent enough version of gud.el.
I'd like to push an alert to my iPhone users that are within a geographic range. I can get their location when my app is "alive," but not otherwise.
Would a good approach be: send the localized alert based on users that appeared "in-range" in the last hour? Otherwise, I'm not sure how to only alert relevant users.
Is there a smarter approach?
The lack of background processing really hurts applications like this. I think your solution is probably the best approach, given that rather severe limitation. However, you definitely should offer the ability to tone this down, as it could start to get really annoying.
