Flutter is continuously updated with new features, performance improvements, bug fixes, platform support changes, and developer tooling enhancements. For developers who build mobile, web and desktop applications with Flutter, keeping the SDK up to date is important for accessing the latest capabilities and maintaining compatibility with supported platforms.

As of August 2026, the latest stable Flutter release documented by the Flutter team is Flutter 3.44.x, with the documentation reflecting Flutter 3.44.7. The Flutter release schedule also lists Flutter 3.47 as the next stable release target for August 2026.

What Is the Latest Version of Flutter?

The current stable release line is Flutter 3.44.

Flutter 3.44 was released on May 18, 2026, as part of the Google I/O release cycle. Subsequent 3.44.x updates have provided bug fixes and maintenance improvements.

The current Flutter documentation reflects version 3.44.7, while the SDK archive shows the 3.44.x stable releases and their corresponding Dart versions.

Flutter Version History

Some of the recent stable Flutter releases include:

Flutter follows a regular stable-release cycle. The official 2026 schedule targets releases in February, May, August and November.

What’s New in Flutter 3.44?

Flutter 3.44 is the latest completed stable release line and contains changes across the Flutter framework, platform integrations and developer tooling.

The Flutter team describes the 3.44 release as a substantial release associated with Google I/O 2026.

When upgrading an existing project, developers should also review the release notes and breaking-change documentation rather than assuming that every existing project will migrate without changes.

Flutter Release Notes

Why Should You Update Flutter?

Keeping Flutter updated has several advantages.

Better Performance

New Flutter releases include framework, rendering and tooling improvements that can improve application development and runtime behavior.

Bug Fixes

Maintenance releases address bugs discovered after the initial stable release.

Platform Compatibility

Flutter regularly updates its support for Android, iOS, macOS, Windows, Linux and web platforms.

For example, the currently documented supported platforms include modern versions of macOS, Debian, Ubuntu and major web browsers.

New Developer Tools

Flutter releases can introduce improvements to debugging, testing, development workflows and DevTools.

Security and Maintenance

Keeping your development environment current reduces the risk of relying on outdated dependencies and unsupported configurations.

How to Check Your Flutter Version

You can check your installed Flutter version using the terminal:

flutter --version

You can also run:

flutter doctor

The flutter doctor command is particularly useful because it checks your Flutter development environment and reports configuration problems.

How to Update Flutter

If you installed Flutter through the standard SDK distribution, you can update it from the terminal.

First check your current version:

flutter --version

Then run:

flutter upgrade

After the upgrade completes:

flutter doctor

Finally, verify the installed version:

flutter --version

Flutter’s official documentation recommends keeping development environments up to date with the latest stable or beta releases, depending on your development requirements.

How to Update Flutter Projects After an SDK Upgrade

Updating the Flutter SDK and updating an existing project are related but separate tasks.

After upgrading Flutter, navigate to your project:

cd my_flutter_app

Then retrieve dependencies:

flutter pub get

You can check outdated packages with:

flutter pub outdated

If appropriate, update dependencies:

flutter pub upgrade

Then test the project:

flutter run

For a production project, don’t update every dependency blindly. Review package compatibility before upgrading major versions.

Check for Breaking Changes

This is one of the most important steps when updating Flutter.

A new Flutter release can contain:

• API deprecations
• Changed platform behavior
• Dependency compatibility changes
• Android configuration changes
• iOS configuration changes
• Rendering changes
• Build-system changes

Flutter maintains dedicated breaking-change and migration documentation for this purpose. The official installation documentation also specifically recommends checking breaking changes and migration guides when upgrading.

Flutter and Dart Version Compatibility

Flutter includes a compatible Dart SDK.

For example, the Flutter SDK archive lists Flutter 3.44.6 with Dart 3.12.2.

Therefore, you generally should not independently install an unrelated Dart version and expect it to work with your Flutter SDK.

Check your versions with:

flutter --version
dart --version

Should You Update to the Latest Flutter Version?

For a new project, using the current stable release is generally the best approach.

For an existing production application, the decision requires more care.

Before upgrading, consider:

• Current Flutter version
• Dart version
• Package compatibility
• Android Gradle configuration
• iOS configuration
• Native plugins
• CI/CD environment
• Automated tests
• Known breaking changes

A production application should ideally be upgraded in a separate branch and tested before deployment.

Stable vs Beta Flutter

Flutter provides different release channels.

Stable

The stable channel is generally the best choice for production applications.

Beta

The beta channel provides access to upcoming features and releases before they reach stable.

For example, the Flutter SDK archive currently lists 3.47.0-0.1.pre in the beta channel, while the 3.47 stable release is targeted for August 2026.

For most developers:

Production → Stable

Testing upcoming features → Beta

Flutter 3.47: What’s Next?

According to Flutter’s official 2026 release schedule, Flutter 3.47 is targeted for August 2026. The listed branch cutoff date was July 7, 2026.

Because the release target does not by itself guarantee that a stable build has already shipped, developers should check the official Flutter release notes before treating 3.47 as the current stable version.

This distinction is important when writing tutorials or documentation that need to remain accurate over time.

Important Changes to Check Before Updating

Before migrating a project, pay particular attention to changes involving:

Android

Check:

• Android SDK
• Gradle
• Android Gradle Plugin
• Java version
• Target SDK
• Edge-to-edge behavior

Flutter has introduced platform behavior changes around Android’s edge-to-edge requirements.

iOS

Check:

• Xcode
• iOS deployment target
• CocoaPods
• Swift/Objective-C plugins
• Native configuration

Web

Check:

• Browser compatibility
• Web renderer behavior
• JavaScript/WebAssembly support
• Browser-specific issues

Desktop

Check the supported versions of:

• Windows
• macOS
• Linux

Flutter’s supported-platform documentation is updated alongside SDK changes.

Common Problems After Updating Flutter

flutter doctor Reports Errors

Run:

flutter doctor -v

This provides more detailed information about the development environment.

Packages Are Outdated

Run:

flutter pub outdated

Then review which packages require updates.

Build Errors

First try:

flutter clean
flutter pub get

Then rebuild the application.

Plugin Compatibility Problems

A Flutter plugin may not yet support your new Flutter or Dart version.

Check the plugin’s latest version and compatibility information before changing your project configuration.

Android Build Problems

Review your:

• Gradle version
• Android Gradle Plugin
• Java version
• compile SDK
• target SDK

Do not randomly change all Android configuration files at once. Identify the specific compatibility problem first.

Best Practices for Updating Flutter

Follow this workflow:

Check Current Version
        ↓
Read Release Notes
        ↓
Review Breaking Changes
        ↓
Create Git Branch / Backup
        ↓
Update Flutter
        ↓
Update Dependencies
        ↓
Run Tests
        ↓
Build Android / iOS / Web
        ↓
Test Application
        ↓
Merge Changes

This approach is much safer than simply running flutter upgrade on a production branch.

Conclusion

Updating Flutter is an important part of maintaining a modern Flutter development environment.

As of August 2026, Flutter’s current stable release line is 3.44, with the official documentation reflecting 3.44.7. Flutter 3.47 is the next release targeted in the official 2026 schedule.

For developers working on existing applications, the safest approach is to:

Check the current version → review release notes → check breaking changes → update Flutter → update dependencies → test the project → verify Android/iOS/Web builds.

The official Flutter documentation should be treated as the final reference when determining the exact latest stable version and migration requirements.
