“Oh, my Flutter” turned 4 years old this weekend 🎉

I'm glad that back in time, I decided to start this project. I'm even more delighted to see what it's grown into - an awesome community with over 4.5k readers across multiple platforms. It's encouraging to keep going.

Thank you for being with us 💙

Andrea Bizzotto along with contributors has compiled all the talks from FlutterCon 24 in one place.

Enjoy! 🤤

An interesting package that allows you to "protect" your application under certain circumstances. For example, when the app goes into the background, a screenshot cannot be taken without the user's knowledge.

Telegram has similar functionality in secret chats.

The package also allows you to respond to events related to "locking" and configure some aspects.

You probably haven't had time to miss Flutter Voronezh yet, but here we go again 😉

On November 18, we will gather another online meeting. Fedor Blagodyr will give a tour through the world of macros and metaprogramming in Dart:

👉 The benefits macros bring to development and the problems they help to solve.
👉 The lifecycle of macros, their types, how they work, and some examples of implementing custom macros.
👉 Personal experiences and challenges developers face when working with macros in Dart.

The event is hosted in Russian language.

The new episode of Observable Flutter is dedicated to working with gradients at a low level of interaction with shaders.

The invited speaker tells and shows how he managed to implement gradients based on a polygonal mesh and how he bypassed the limitations of Fragment programs to improve performance.

The speaker's Mesh package, which makes it easier to make cool gradients, will also be discussed.

Quite old, but no less useful examples of implementations of various architectural approaches such as MVU, MVC, BLoC, Redux, Mobx and so on.

Felix Angelov and Remi Rousselet have managed to make their mark as contributors.

Sometimes it is useful to run through and remember something, especially with the presence of Web Demo for almost every example.

📌 Examples

Inefficient memory usage in an application can significantly impact the user experience, from minor lags to unexpected crashes.

📌 Read how to avoid this in Majid Hajian's article.

#article

The new Observable Flutter episode continues the topic of shaders from the previous one.

The invited speaker touches on the topic of Image filters and demonstrates a large number of the coolest demos.

Earlier, we already talked about an interesting implementation of Dismissible from the same author.

The speaker also touched on the Glitch effect and I remembered my package, which also had an implementation on shaders.

Shaders to all 🤘🏻

The Flutter plugin for VSCode has received another update. It contains:

👉 notification about using soon-discontinued Dart and Flutter versions;
👉 fix for dependency tree displaying if the folder and package names do not match.

📌 This and much more in the detailed changelog at the link.
https://dartcode.org/releases/v3-100/

#update

In upcoming versions, generating the .flutter-plugins file will stop and leave only .flutter-plugins-dependencies.

This will presumably happen in the N+1 stable release (the first stable release of 2025).

Most users won't have to do anything during the transition itself. However, users with old build scripts will have to tweak them a bit.

📌 More details at the link.
https://docs.flutter.dev/release/breaking-changes/flutter-plugins-configuration

#announcement

One more technical change that will happen in future releases.

Flutter will no longer generate a synthetic package:flutter_gen or modify the application's package_config.json. Instead, the files will be generated in the project directly.

This will happen presumably in the N+1 stable release (the first stable release of 2025).
