Release Notes Flutter 1.5.4

Chris Sells edited this page May 7, 2019 · 3 revisions

What’s new in Flutter 1.5.4

In addition to continuing to focus on quality and stability since the 1.2 release, the Flutter 1.5.4 stable release adds a set of new features as we approach the Google I/O conference. Further, Apple has a deadline for building against the 12.1 version of their iOS SDK, which we now do in this update. You can meet Apple’s requirements simply by pulling down the 1.5.4 stable release, building and updating your Flutter app in the Apple Store.

Also, this build sees fixes for the two regressions we saw in Flutter 1.2:

  • #28640 NoSuchMethodError: **android.view.MotionEvent.isFromSource was closed and fixed in all versions after 1.3.7
  • #28484 Widget rendering strange since Flutter update:** a change was made fixes this regression in 1.4.0

Finally, for details about other fixes and new features, read on.

Breaking Changes

Our recent survey showed that Flutter developers prefer a breaking change if it means that it improves the API and behavior of Flutter. Of course, we still make breaking changes sparingly. The following are the list of breaking changes in this release along with links to a full description of each change and how to handle it in your Flutter code.

Severe Performance and Crash Changes

Framework Changes

In addition to platform specifics, we continue to push on the core of the Flutter framework.

Further, the IDE plugins for Flutter have had a number of updates since the last stable release of Flutter.

Dynamic Update (aka Code Push)

As a final note, we’re nearly at the midpoint of the year, when it’s time to reassess the areas where we can have the most important, we've decided to drop plans for dynamic updates (aka code push) from our 2019 roadmap. If you’re interested in the reasons why, you can read the detailed explanation. Dropping this work allows us to increase our focus on quality as well as our experiments in Flutter for web and Flutter for desktop.
