Origins and Motivation (2015)

Flutter's story begins at Google in 2015, but to understand why it was created, we need to look at the problems Google was trying to solve:

The Problem:

• Mobile development was fragmented: separate codebases for iOS and Android
• Existing cross-platform solutions (PhoneGap, Cordova) were slow and didn't feel native
• Google needed a better way to build high-quality apps across platforms
• Web technologies were being used for mobile, but performance suffered

The Vision: Google engineers, led by Eric Seidel and a small team, envisioned a framework that could:

• Achieve true native performance
• Enable fast development with hot reload
• Provide beautiful, customizable UIs
• Work across all platforms from a single codebase

Sky: The Prototype (2015)

Flutter didn't start as "Flutter." It began as an experimental project called "Sky", which ran on Android only. The Sky prototype was first demonstrated at the Dart Developer Summit in 2015.

Key innovations in Sky:

• Aimed for consistent 120 fps performance
• Used Dart language (which Google had created in 2011)
• Challenged the assumption that mobile apps needed platform widgets
• Introduced the idea of rendering everything with its own engine

Birth of Flutter (2016-2017)

May 2016: Sky was renamed to "Flutter" at Google I/O 2016.

Alpha Release (2017): Flutter's first alpha version was released, though it was still considered experimental and only supported Android.

During this period:

• The team refined the widget system
• Dart was optimized specifically for Flutter's needs
• iOS support was added
• The architecture was solidified

Flutter Beta (2018)

February 2018: Flutter reached Beta 1 at Mobile World Congress in Barcelona.

This was a turning point:

• Both iOS and Android were now officially supported
• Major companies began experimenting with Flutter
• The developer community started growing rapidly
• Tooling improved significantly

Milestone Apps:

• Hamilton Musical app: One of the first high-profile Flutter apps
• Alibaba: Started using Flutter for their Xianyu app (50+ million users)

Flutter 1.0 - Production Ready (December 2018)
