finally , Technique of the week
Thank You Flutter

[@trevornatiuk1031]

If I use List.generate() inside a build method, I will have to generate the list every time I build the widget, no? I feel like if I can avoid having to generate the list every build, I could just run the generate constructor and set that to an inst var.

[@ahmedmohamed1340]

Use statemanagement to handle build method calls

[@roman-proshin]

I’d wrap that logic into a new widget so that the list is only generated when the widget is rebuilt.

[@mikopiko]

Put it outside the build method?

[@agustinbjr]

Correct. Though It is useful if your List contents depend on a changing state (which rebuilds the widget)

[@garthbartin]

It's literally just 5 elements. Don't perf optimize something that doesn't take any time.
You don't bat an eyelid about writing a row with a list literal written out inside of it do you? Well that's constructing the list on every build too (assuming it's not const).
Part of being good at frontend is learning to forget "time complexity" and other stuff you learned in school-its almost never the bottleneck.

very nice.
can you show us the most efficient way of doing a bottom navigation which will keep its state while switching tabs?
greets

[@jimking2692]

Use pageview then nest the pages in the children

[@flutterdev]

Thanks, @xxThemoritzxx! This Code With Andrea resource on bottom navigation might shed some light! → goo.gle/3xAoObJ

Hi, can you please make a video on how we can collaborate on Firebase with Flutter! I am working on an app with my team and facing some problems.

[@chenchou]

where does StarIcon() come from please?

[@mofidulislam2837]

Its just an example,Consider it as Icon(Icons.star)

[@flutterdev]

StarIcon is meant to be a generic widget used to illustrate the example. You could replace it with any other widget like a button or card.

[@kamaravichow]

Sounds like AI generated voice and flutter team is on auto pilot

[@aymendenoub2503]

Is Flutter running out of widgets so we're doing "techniques" now?

[@TheOrator_Ese]

Which widgets are you lacking when you have dart? Lol skill issue

[@mikopiko]

Yeah, Widget of the Week could start covering third party packages too?
