no difference

Can we give them height and width?

So instead of nesting conditions, you're repeating code How is that cleaner?

very useful content

Store all conditions as booleans at the top of the code (you can cast if you need to). Use the booleans in the if-statements. Now there's no nesting, and there's also only one return value

Great tutorial 👏, I highly recommend

Ah the "six line if statements" hell😂

Remember, there is no right or wrong method when it comes to coding. If it works that's what matters

When you're trying to figure out alignment of your widgets (particularly, at 1:45:00), you can do Ctrl-Shift-P (not sure about mac) in VS Code and type "Toggle Debug Painting" to enable "Flutter: Toggle Debug Painting". This will let you see how big the columns/rows are, how much space they're using, why things are located at certain places and so on. Also thanks for the tutorial, it helps a lot!

It's not that important for your code to be easy to read. Much more important that it runs well.

Why not do (condition && condition && condition)

Decorator pattern

Simplify more &&

While nested ifs is never a solution, having a lot of return blocks is not that good either (not sure as of right now, but Sonar also had a "clean code" rule that enforced a single return value per function, and I also recall cyclomatic complexity was affected by the amount of returns. I'd rather have a single "isUserLoggedInAndAdmin" which wraps all the required logic (and can be used everywhere else) abd a single if/else block. Much more readable and easier to debug as specific logic is wrapped where is actually belongs, imho You could even have two functions if you want to enforce maximum modularity: "isUserLoggedIn" and "isUserAdmin". This may look overkill because your example is using basic booleans, but try fetching those statuses out of a token or a db every time on your code and it quickly becomes a copy/paste smell on unexperienced hands..

now i know more of what is possible in flutter. nice work👌

This code still ugly, you can use &&, or why the hell you need to check if logged in while you are able to check user role?

Orrrrr: If (WiFi and login and admin): //do stuff Else //do something else

What about: getCaffeine(type){ return (type == 'Coffee') ? '95 mg' : (type == 'Redbull') ? '147 mg' : (type == 'Tea') ? '11 mg' : (type == 'Soda') ? '21 mg' : 'Not Found'; }

dart library 'dart.ui' is not available on this platform ????? what should i do i m really annoyed

This example shows, that the language lacks the "unless" keyword.

Amazing, thank you.

Its funny how often wrong gets redefined in programming. Way...back When I was a kid, functions have a single exit point. So you had to nest by definition.

Thanks for this toturial

1.this is just an example, everybody need to calm down with the "security" stuff... 2.early return is not necessarily a better option 3.try to avoid big nested IF statement.. obviously 4.nobody cares about your unit test, except maybe at university 5.Vive le Quebec !!

I really appreciate you guys taking your time to explain this to us. Thanks so much.🙏🏾🙏🏾

That is poor software design, not following OOP principles, SOLID, etc.

Fine

Can’t say for RefactorGPT to crawl through my code and do this + security all for me 😂

Please create video for flutter web nav menu with submenu like we use in bootstrap

Thank you so much. You made me understand Flutter within a twinkle of an eye. God bless!!!

Better yet, use an assertion and handle the exception. Why have a function that is supposed to do something and just silently fails while printing a log. Thats just bad code right there. Best bet here is 3 assertions and then a if (wifi && login && admin) to further protect it

Is it possible to change the buttons text? And is it possible to close all the steps? (too bad the current step is not nullable..)

I guess you've never heard of, "one way in, one way out." There is also the problem of lazy coders throwing a quick line of code at the end of a function, thinking it will be run when the function exits. There are uses for early returns, but I don't think readability is a good one.

Legends think of function pointers💪💪

So its the same

don't you have a french channel for the same content ?

very well explanation of clean architecture using a cone. thank you!

This video is wrong

I'm not a programmer but I know for sure that must be there's "or" "and" "not"statement?

If you encounter this problem with YOUR hand written code. Close it up, set down that keyboard big man. This ain't the industry for you. You should ALWAYS write code to be more smart, rather than just what is easiest. If you're starting out, never do this. This shows others reading your work that you make spaghetti code.

I like this video, it simple to understand the hole of clean architecture things

how about this: if (wifi && login && admin) seeAdminPanel(); else { if (!wifi) debugPrint("Must be connected to WiFi"); if (!login) debugPrint("Must log in to your account"); if (!admin) debugPrint("Must be an administrator"); // this will also print more than one of these if more than one is true }

This was actually a usefull vid I might use it

I think in python it would be like: if (wifi): pass else: print("error") return

OR
