Flutter 3.32 Released: Web Hot Reload and New Features

Flutter 3.32 has arrived with exciting new features that enhance both developer experience and app performance. This release brings experimental web hot reload, improved iOS fidelity, and powerful new tools.

Key Features

Web Hot Reload (Experimental)

The most anticipated feature in this release is web hot reload. Available with the --web-experimental-hot-reload flag, this feature dramatically speeds up web development:

flutter run -d chrome --web-experimental-hot-reload

This brings the beloved hot reload experience from mobile to web development, allowing instant updates without full page refreshes.

Cupertino Squircles

• CupertinoAlertDialog now uses authentic iOS shapes
• CupertinoActionSheet provides true native appearance
• Improved visual consistency with iOS platform

Flutter Property Editor

A new IDE tool makes widget development faster:

• Edit widget properties directly in your IDE
• Access documentation without context switching
• Visual property manipulation
• Streamlined development workflow

Performance Improvements

This release continues to optimize the Impeller rendering engine with:

• Reduced frame rendering times
• Better memory management
• Smoother animations across platforms

Getting Started

Update to Flutter 3.32:

flutter upgrade
flutter doctor

The web hot reload feature requires opt-in through the experimental flag, giving teams time to test before full adoption.

What's Next

The Flutter team continues working on performance improvements and platform-specific optimizations, with more exciting features planned for upcoming releases.
