Announcing Flutter 2.2 at Google I/O 2021

Growing momentum for the leading UI toolkit for multiplatform development

Building on the foundation of Flutter 2

Flutter 2.2 is built on the foundation of Flutter 2, which extended Flutter from its mobile roots to incorporate web, desktop, and embedded usage. It is uniquely designed for a world of ambient computing, where users have a wide variety of different devices and form factors and are looking for consistent experiences that span across their daily lives. With Flutter 2.2, enterprises, startups, and entrepreneurs alike can build high-quality solutions that can reach the full potential of their addressable market, allowing creative inspiration (rather than target platform) to be the only limiting factor.

Flutter is now the most popular framework for cross-platform development.

A recent mobile developer study highlights the growth of Flutter. Analyst firm SlashData’s Mobile Developer Population Forecast 2021 shows that Flutter is now the most popular framework for cross-platform development, with 45% of developers selecting it, representing 47% growth between Q1 2020 and Q1 2021. Our own data confirms this shift towards Flutter; in the last 30 days, more than one in eight of the new apps in the Play Store are built with Flutter.

Introducing Flutter 2.2

The Flutter 2.2 release is focused on improvements to the development experience to help you deliver more reliable, performant apps to your customers.

More than a Google project

While Google continues to be the primary contributor to the Flutter project, we’re delighted to see the growth of the broader ecosystem around Flutter.

Building Great Experiences

More than anything, we built Flutter to help developers build great experiences. We are animated by the idea that app development can be better: that we can empower you by removing traditional impediments to reaching your audience.



Flutter is Google's mobile UI framework for crafting high-quality native interfaces on iOS, Android, web, and desktop. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source. Learn more at https://flutter.dev
