We continue the topic of rendering optimization using Canvas. Last time we talked about drawAtlas, and today we will show and tell about drawPoints. This method allows you to very optimally draw a set of points with different modes.

Just like drawRawAtlas, there is drawRawPoints, which provides even greater performance.

The new release of Observable Flutter greets us with a detailed analysis of home_widget directly from the author.

We have already touched on this package before, but since then there have been updates, and the ability to make "home widgets" interactive has appeared.

The new version of Flutter goes as always together with the new version of Dart. This time, in terms of new features of the language, the release is more of a formality. Pubdev, on the other hand, got several notable new features:

👉 Pub workspaces;
👉 Pub download counts.

Some vulnerabilities were fixed in the 3.27:

👉 missing sanitization checks for file_selector_android and image_picker_android packages;
👉 Deserialization leads to adhoc code execution for shared_preferences_android
👉 Malformed APNG images could cause out-of-bounds memory writes

Severity: Medium 4.3/10

Recommended action: updating package versions to 0.8.12+18 of image_picker, 0.5.1+12 of file_selector and 2.3.4 of shared_preferences and updating to Flutter 3.27 stable.

The final post on the topic of efficient drawSomething, and this time it’s about drawVertices, which allows rendering vertices in two ways: optimized or highly optimized. 😁

No example explains this amazing method better than Filip Hracek.

Another clever way to optimize using SnapshotWidget.

This widget allows you to take a "snapshot" of a child widget as a ui.Image and display it when needed. This can be useful for short animations applied to "expensive" effects like blur.

This is how the ZoomPageTransitionsBuilder works under the hood.

For many, pragma is something "magical" and unclear, but thanks to Vyacheslav Egorov, we have the opportunity to understand what it is, the benefits it can bring, or the harm it might cause.

This article will list existing annotations, explain what they do, and evaluate how safe their usage is.

A pleasant article on gesture recognition.

Notable for demonstrating how and why you can override DeviceGestureSettings.

It also includes examples of transformations (scaling and positioning) based on data provided by GestureDetector callbacks.
