What’s new in Flutter

Flutter 3.38 & Dart 3.10: A major release for modern mobile development

Flutter 3.38 shipped alongside Dart 3.10, introducing some of the most meaningful upgrades of the year. Between required migrations, language improvements, and AI-enhanced workflows, November became a pivotal month for engineering teams across industries, from fintech and healthcare to media, retail, and enterprise SaaS.

Whether you're building apps for Android, iOS, web, or desktop, these updates impact your roadmap.

Dart 3.10: More expressive, more capable, more productive

• Dot shorthand syntax enabled by default

Cleaner, more readable syntax now streamlined across large codebases.
This brings Dart closer to the elegance of languages like Swift while maintaining its strong typing and tooling reliability.

• Build Hooks are now stable

This unlocks a major leap in native interoperability.
Teams integrating Rust, C++, Swift, or system-level libraries can now rely on predictable build steps with significantly less boilerplate.
Ideal for apps requiring AI acceleration, BLE integrations, cryptography, or high-performance native features.

• New analyzer plugin system

Companies can finally enforce custom static analysis rules, strengthening consistency and code quality across distributed teams and nearshore development partners.

Flutter 3.38: Required migrations + big performance wins

• Android 16KB page size support (mandatory)

Google Play now enforces this for apps targeting Android 16.
If your app isn't updated, expect rejected submissions.

• Java 17 is now required

Teams still using Java 11 or older build pipelines will need to upgrade.
This update also aligns Flutter with modern Android development standards.

• Full iOS 26, Xcode 26, macOS 26 support

Includes the UIScene lifecycle migration, improving stability on Apple’s latest devices and preparing apps for 2026 hardware cycles.

• Critical Android memory leak fix

A major memory leak impacting all apps since Flutter 3.29.0 was resolved—leading to better performance and fewer crashes across production apps.

• Web Dev configuration support

A new configuration format enhances team consistency and improves multi-environment workflows.

• DevTools improvements

Fixes targeted the biggest developer pain points, especially when debugging performance issues in production apps.

• Gemini CLI extension + MCP integration

This deepens Flutter’s alignment with AI-driven development.
Teams can now use AI for scaffolding, code generation, documentation, architecture setup, and more directly from the CLI.

This update positions Flutter as a first-class ecosystem for building AI-powered apps at scale.

Trends & highlights

AI-Enhanced engineering is becoming standard

The new Flutter extension for Gemini CLI confirms the direction the ecosystem is heading:
AI isn’t a separate layer anymore,  it’s part of the development workflow.

From generating code to improving developer velocity, the MCP + CLI integration is a strategic advancement for both startups and enterprise teams investing in:

• AI copilots
  
• Agentive applications
  
• Personalized user behavior prediction
  
• Intelligent UI generation
  
• Natural language interfaces
