Flutter Hot Reload. Wow!

I recently wrote a blog post outlining some of the interesting features of Flutter, Google’s new framework for creating beautiful, native-ish, cross-platform mobile apps. But I left off one of the most important features.

Suppose you have your flutter project open in IntelliJ and your Android or iOS device attached to the USB port.

  • Clicking the “Run” button (or Shift F10) launches the app on the attached device.
  • And here is the cool part: Change a piece of source code. Click the “Hot Reload” button (or Alt-Command-Semicolon). The app’s UI (on the device) instantly updates to reflect the change.

So cool!!

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
