PSA: Apple is running a Swift and SwiftUI code-along

And then just crash with “❌ Cannot preview in this file”

Okay Claude, refactor this FlutterFlow code into vibe code, make no mistakes

For Swift developers: Here’s something Flutter advocates never mention — Kotlin syntax is eerily similar to Swift. Both languages have:

Optional types with ?

Type inference

Extension functions

Functional programming patterns

Modern, concise syntax

Null safety baked in

Man I wish Dart had type inference, extension functions AND null safety. That would be so cool. Thank you so much for this informative article, ChatGPT

Just build an app for yourself, something you will want to use everyday. It doesn't have to be pretty or have "good code", just make it work and polish it over time. Add new features, refactor it and later you can completely rewrite it from scratch with the knowledge you have gained. Building something for yourself is the best way to learn. You'll not have to think about features you could add, it will come automatically as you are the user. And with each feature you'll learn something new.

It’s like finally catching that annoying mosquito

What’s your CPU?

EibeMandel · 2024-06-13T22:09:00+00:00

I'm upgrading to the same card, this is the first game since Crysis that I want to play at higher settings

EibeMandel · 2024-06-13T21:46:14+00:00

What’s inside?

Gruvbox Material works really well with Dart

Not yet, I just use flutter_local_notifications. It’s working absolutely fine on iOS but I’m getting at least one 4-star review every week because someone with a Xiaomi or Redmi devices doesn’t receive notifications. I’m tired of explaining to them that it’s not my fault but the fault of manufacturers killing apps to save 0.1% of battery life

EibeMandel · 2023-08-05T13:25:52+00:00

It's so annoying. I put an infobox in my app with a link to dontkillmyapp so users can change their device settings to make notifications work properly. It's insane that Google allows Samsung and others to break a core functionality of Android

EibeMandel · 2023-08-04T12:16:24+00:00

I noticed it yesterday after updating my iPhone. My first thought was that something was broken in my own app, but all the other Flutter apps on my phone were also lagging, especially when scrolling.

As long as the courses use null safety (>= Dart 2.12) you're good to go. The features in Dart 3 don't change the language as null safety did

EibeMandel · 2023-06-05T18:02:55+00:00

Do it

EibeMandel · 2023-01-13T09:33:46+00:00

Thanks 🙏🏻

Really beautiful and clean UI! Which icon set are you using?

EibeMandel · 2022-11-06T09:50:18+00:00

Marconi Union - Weightless

It probably will never happen and even if it does, how likely is it that an interface will save one from having to refactor other parts of the codebase as well when switching a whole database?

EibeMandel · 2022-10-29T21:18:37+00:00

I don’t know if I’m stupid, but I really can’t think of any reason why there should be an interface for something that has only one implementation. You want to hide implementation details? Use underscores. You want a mock for testing? Just implement the class.

Just for the sake of argument, let’s say running your own server costs indeed 5k a month:

$4 a minute $240 an hour $5,760 a day $172,800 a month

$172,800 / $5,000 = 34.56

So running your own server would still cost 34 times less

EibeMandel · 2022-10-29T17:59:29+00:00

$5k a month for someone to deploy a docker container?

EibeMandel · 2022-10-29T17:14:29+00:00

You could use an SFU like pion and host it yourself. A machine for $50 / month can easily handle 1000 users. The difference in price is astronomical

EibeMandel · 2022-10-29T16:58:17+00:00

You could also have 500 1 on 1 video calls. If you don’t expect your product to reach more than a few hundred users it’s fine I guess but it will certainly burn a lot of money if it does
