messages dropped when sending many of them

[psomani16k]

I am trying to text updates of the progress of a process which leads to many messages being sent with very little time in between them. I noticed some of these messages get lost and do not reach flutter. Is this expected behavior? if yes, how can I overcome this safely in rust?

Thank you

If you're using StreamBuilder or any widget builder, any messages that arrive within a single frame(usually 16ms) can be ignored. This is the default behavior of Flutter widget builders. To handle all messages, you can directly use Stream.listen method in Flutter instead.

Below are links that would be of a help:

Thank you for the quick reply!

@temeddix I think it should be great if we have a very simple example of Stream.listen because the first time I tried I didn't understand how to use it since I didn't know much about dart and just wanted to use flutter as frontend while I already know rust

Or at least add a link to some docs because I assumed Stream and even StreamBuilder was from rinf

The clarifications or dart docs references may save some hours to people new to flutter and dart

@rurigk That's a good idea. What do you think about adding links in the footnote section of the page below? Or do you have any other suggestions for where to add links?

Links in the footnote are ok but I still like the idea of adding an example

Docs have been updated as per your suggestion:

• Improve guides about Stream.listen #524

Links and examples are now all included. Thank you for your feedback :)
