This feels like the sample of Angela Yu from her flutter course

Async and await is where Flutter tries to wash, spin and dry your clothes all at the same time so things look like they are going faster! When the actual result is ‘spin’ wasting it’s time because the water is still coming in and ‘dry’ wasting it’s time doubly so. Your washing is done in a third of time but it’s all soapy and soaking wet FFS. It often can’t even possibly wait for an int or a bool to be given a new value before it draws a page, no I’ll do that after I’ve rendered the page with garbage and then go back and change the value. Then it’ll return back to the first page and go back and finish code written for the second page, that way the end user will be so impressed at how fast things can get utterly effed-up! And it’s not as if things are even genuinely being done any faster because it only uses one thread! The ‘time saved’ is actually lost because our single thread now has to switch between tasks and try to keep track of what is when! Is all the confusion this mash-up creates actually worth anything? If something takes some time to complete is it so terrible to show the user that they are waiting? Because like it or not they are still going to be waiting as nothing is actually happening any faster!

How to implement security in fluttter app

[BernardoFuenmayor]

Mi idioma es español pero entendi perfectamente el uso de future async await very thanks

[TheCodeWhisperero]

I don't get that, why should you wait and async when you decide the time (3 seconds) by yourself?? shouldn't we wait until the data gets back from the server but not by writing how much duration it needs!!
