0:43 "Create a tear off when a what now will do?"

I lol'd! Good job explaining this! My mnemonic is that tear-off literally *tears off* the parens.

Nice! I was waiting so much to use the constructor tear-offs. I got obsessed with clean code practices since I turned on almost every linter rule and the constructors always looked bad without tear-offs.

Wow...I've been using tear offs in callbacks but didn't know. I've heard about the new constructor tear feature in Dart and I've been confused because I didn't know what a tear of was. Thank you for this and thank you Dart team

Surprisingly I have been using this for a while without knowing it was cool 😅

[julius]

I love this guys' energy for some reason

Great content as always.Thank you Craig and flutter team.

Thanks for the explanation of a tear-off. I had been wondering what all this hubbub regarding Dart tear-offs was about. I thought... What even is this new concept Dart has created called tear-offs? So now I know that it really is just syntactic sugar which the Dart compiler expands to a closure calling your function. Makes sense, and saves us from having to type a few more braces and parentheses. And we definitely don't need any extra bracing in our Flutter UI code...

Learned the terms of the concepts that I use daily

Great thumbnail ! 👌

And video, like always

Hey flutter team, i was wondering if you can make a episode of "hell ya! Interesting development show" where you just focus on creating beautiful ui. Please🥺

Nice done. In case I miss it why are tear-off better then lambda? Is it because of better readability or does it have performance impact. What are the implications, that would nice too, to explain, just for next time. Anyway great video serie

[eldadario]

flawless I will refactor my codes tomorrow

[shehzadahmad]

😆 okay I didn't knew what the tear-offs were but I have been using it for long time 😂😂. Well well well, now I know its name too, it's called tear-offs ❤

[abdulazeezoshinowo]

This makes the codebase DRY. Very informative!!

[RawPeds]

It's like a method reference in Java.

[gofudgeyourselves]

But if you have to pass some input to the method then in that case you will have to use lambda instead of tear off, correct?

Hi! I am new to flutter. So a tear off basically removes the unnecessary use of lambdas.
So the benefit is:
1. Clean code practice: Supply the function when it needs to be supplied, call a function when it needs to be called.
2. Not using lamda when we can do without using it. I guess, it is memory efficient.

Am I right or am I not?

Tear-offs work with optional parameters that has n-1 && n != 0.

[mehmetedex]

I always used it but didn't know what its called until now

Hello My name`s Amin,
I`d like to learn flutter zero to hero.
does anybody know any blog or anything else to learn about Flutter Programming ?
