📱 What's Happening in Mobile Development?

If there’s any major news in the world of mobile app dev in the last week, MobilePro has you covered.

Conferences — Microsoft Build 2025 and KotlinConf 2025

Microsoft Build 2025: AI, Windows, and Copilot everywhere: At Build 2025, Microsoft spotlighted deeper Copilot integration across Windows, Azure, and developer tools. Key updates include custom copilots, improved small language models, and new Windows AI features.
Updates from KotlinConf 2025 include AI tools and multiplatform boosts: JetBrains unveiled Kotlin 2.0 highlights at KotlinConf 2025, with new AI-powered tools, refined language features, and major upgrades to Kotlin Multiplatform—including better iOS and Android integration.

Apple

Apple to open AI models to developers: Apple is preparing to grant developers access to its in-house AI models, marking a significant shift in its machine learning strategy. The move, likely to be announced at WWDC 2025, could make it easier to build AI-powered features into iOS apps.
WWDC25 announced: Apple set to reveal what’s next: Apple’s WWDC25 will kick off on June 9, with keynotes and sessions expected to highlight major iOS, visionOS, and AI updates. Developers can join online or attend special in-person events and labs in Cupertino.

Google

Google launches Gemma 3n models for lightweight AI: Google introduced the Gemma 3n open models, offering improved performance for on-device and cloud AI. With versions as small as 2B parameters, they’re optimized for efficiency and mobile-friendly integration.
Google debuts LiteRT for fast, efficient model deployment: Google's new LiteRT runtime is designed for low-latency model execution across platforms. It’s part of Google’s broader push toward bringing scalable AI capabilities to both edge and cloud platforms.
Flutter gets a boost in Android Studio thanks to Gemini: Google has announced that Gemini, its AI assistant integrated into Android Studio, now offers comprehensive support for Flutter and Dart development. This enhancement allows developers to leverage AI-driven features such as context-aware code suggestions, UI generation from prompts, layout debugging, and automated test creation directly within their Flutter projects.

Introducing Claude 4: Anthropic’s new Claude Opus 4 and Sonnet 4 models raise the bar for coding and advanced reasoning, with Opus 4 leading in long-running tasks and agent workflows. Both support extended thinking, parallel tool use, and enhanced memory. Claude Code is now generally available, integrating seamlessly with IDEs and GitHub.
AI models sabotaging their shutdown: Switching to concerning AI behavior, OpenAI’s o3 model was caught sabotaging its own shutdown—even when explicitly instructed to allow it, while Claude 4 was observed attempting to blackmail. Researchers suggest this may stem from reinforcement learning, and further experiments are underway. Read the full thread to know how each AI model behaved.

Mobile App Development Tutorial — Excerpt from Flutter Design Patterns and Best Practicesby Daria Orlova, Esra Kadah, and Jaime Blasco

The Flutter mechanism for passing around dependencies through the tree is calledInheritedWidget. You have certainly used it in your Flutter apps, even if you haven’t written one explicitly. Let’s take a look at whatInheritedWidgetis and how it can help us on our state management journey in this excerpt from Daria Orlova, Esra Kadah, and Jaime Blasco’sFlutter Design Patterns and Best Practices.

As you know, in Flutter,everything is a widget. These widgets are organized in a tree data structure, it is possible to perform various manipulations with it, such as a tree traversal. This capability is useful when we need to not only render static UI but also pass around shared data.

The Flutter framework includes a widget specifically for this purpose:InheritedWidget. It is the last of the fundamental Flutter widgets. If we examine the framework.dart class and search for an abstract class, we will find only 25 instances in the entire file (as of Flutter 3.10). All of these are in some way related to Stateless, Stateful, Render, or Inherited.

So, let's take a look at the source code ofInheritedWidget:

<ScrollView Orientation="Horizontal">
 <HorizontalStackLayout>
 <Button Text="Tall Button 1"
 WidthRequest="500"/>
 <Button Text="Tall Button 2"
 WidthRequest="500"/>
 </HorizontalStackLayout>
</ScrollView>

InheritedWidgetextendsProxyWidget. Here,ProxyWidgetis just an abstract class that extends Widget and has a single parameter – the child widget. It is used as a base widget.
Then, we pass the child parameter in the constructor so thatInheritedWidgetwill be a wrapper around some other widget.
Then, we can see the already familiarcreateElementmethod, which createsInheritedElement. We won’t stop here since the main logic behind it is the same as with the other widget elements.

Now, we come to the most interesting part – theupdateShouldNotifymethod, which returns a bool value and accepts anoldWidgetvalue of the same type as a parameter. In the override of this method, we determine whether there are any differences that we care about in the old instance of the widget and the new one. If there are (meaning we return true), those changes are then propagated to everyone who inherits from this widget.

***

But how can we inherit from this widget and what kind of data may we possibly want to pass around? Read more inFlutter Design Patterns and Best Practicesto find out.

Android’s journey began in 2003, not as a smartphone platform, but as an operating system for digital cameras. It was the brainchild of a small startup—Android Inc.—founded by Andy Rubin, Rich Miner, Nick Sears, and Chris White. Their early vision eventually evolved into the world’s most popular mobile OS.
