What are some VSCode extensions you can use to speed-up your Flutter workflow?

Here's a thread with my favourites! 🧵
When creating model classes, you'll often needs methods such as:

• copyWith()
• toString()
• toJson()
• fromJson()
• toMap()
• fromMap()
• == operator
• hashCode

Use the Dart data class generator to create them all in one go!

If you use Riverpod, you'll quickly get tired of typing out all your providers and consumers by hand.

The Flutter Riverpod Snippets extension makes this a lot easier!

Do you want to know if you make mistakes as you type?

The Error Lens extension improves the highlighting of errors, warnings, and other language diagnostics, and I find it immensely helpful.

Better Comments helps you improve your code comments by highlighting alerts, notes, TODOs, and more.

The Advanced New File extension lets you create files anywhere in your workspace, using your keyboard only.

(and we all know that every time we touch the mouse a cute animal suffers, right?)

Unless you've been living under a rock, you'll know about GitHub Copilot.

It's an AI pair programmer which suggests line completions and entire function bodies as you type.

(it even helps me write documentation and marketing copy! 🤯)

Of course, you're free to choose whichever theme you like best.

Though this Official Dracula theme is my favorite.

But these are the ones I use all the time. 👌

Can GPT-4 and GPT-3.5 play Wordle? 🤔

I decided to find out! Here's what I discovered:

✅ GPT-4 understands the game and can improve on each move
❌ GPT-3.5 doesn't quite get it 😅

Want to know all the details (prompt & answers)? Then read on! 🧵 GPT-4 completed Wordle in 4 moves: - apple (XXXXO) - ember (
First of all, I've used the same prompt for both models.

I tried to be very explicit about the game rules and provided an example.

Here's what it looks like. 👇 I need your help playing Wordle. Your job is to guess an exi
Here's how things went with GPT-4.

First three guesses: Yes, I understand the rules. I will try to guess the 5-lette

I know that many people out there are looking for their first tech job (Flutter or otherwise) and times are tough.

Having hired talent twice in the last year, I received many applications but very few good ones.

So here's some advice from a "hiring manager" perspective.

🧵
If you knew you had FIVE seconds to make a good impression, what would you do?

This is not a hypothetical question.

If a hiring manager has 50 applications sitting in the inbox, how would they quickly tell the good from the bad ones?

In other words, how do you stand out?
Things that go a long way:

1️⃣ competence
2️⃣ enthusiasm
3️⃣ trustworthiness

Let me elaborate on each one. 👇

If your users speak another language, you’ll need to localize your Flutter app 🗺

Here’s how to setup Flutter app localizations in just 5 minutes, using code generation.

Also covered: template vs non-template files and synthetic vs non-synthetic package. 👀

🧵 Image
1️⃣ As a first step, we need to add the required packages to the pubspec.yaml file. Image
2️⃣ Create l10n.yaml at the root

✔️ arb-dir is the input folder where Flutter will look for the localized strings
✔️ output-dir is where the localizations classes will be generated
✔️ template-arb-file is the main template that contains a description for each localized message Image

What's the difference between errors and exceptions in Flutter?

→ Errors are programmer mistakes. They are fatal and we should not try to recover from them
→ Exceptions are failure conditions that are out of our control. We should handle them and recover gracefully

Thread 🧵 Image
Errors are fatal and when they happen the program *cannot* recover normally.

→ we want to discover (and fix) them as early as possible in the development process
→ we should track them in production using a crash reporting solution, so that we can measure impact and severity
The most common errors we may encounter are:

- AssertionError
- TypeError
- ArgumentError
- RangeError
- UnimplementedError
- StateError

and many others.

They all *extend* the base Error class, and the full list of errors can be found here:

Sometimes we need to write business logic inside classes that have multiple dependencies.

To do this, we can pass the dependencies as constructor arguments.

A much simpler solution is to pass `ref.read` as an argument.

Here's a thread with all the details. 🧵
Reader is just a function we can use to read a provider's value, *just once*.

And once we get the underlying value (a repository in this case), we can call methods on it.

Note: when we want to access a provider inside a widget callback, we do exactly the same thing.
An alternative way of doing this is to pass "ref" directly.

As a result, we have to call "ref.read(provider).someMethod()" inside our class methods.

Though if you only ever need to read (and not watch or listen), using Reader makes your intention more explicit.
