Flutter - Development technology (Web/Mobile Android/Mobile iOS)

Flutter 1.17 and Dart 2.8

Perhaps the biggest news so far with this slew of announcements was the release of Flutter 1.17, including Dart 2.8. Flutter 1.17 offers performance and memory improvements on all platforms, but you’ll see the biggest boosts on iOS, with the adoption of Apple’s Metal subsystem for graphics rendering. For Android too, you’ll see improvements, particularly with the new optional fast start debugging mode, which offers a 3x speed boost with no changes to your code.

Beyond the new features mentioned in the blog post, one feature that some of you have discovered is the updated error display on release mode builds. For release mode builds only, we’ve disabled the “red screen of death” that appears when one of your widgets is incorrectly configured. Many of you told us you’d like to see a less… prominent message in the rare situation that you ship an application with a bug, and hopefully this changed default behavior is a better alternative. (For those of you who want something else, you can use the ErrorWidget.builder property to further customize this.)

It’s exciting to see that, as of the time of writing, two-thirds of you have already upgraded to 1.17. We’d encourage the rest of you to upgrade at your earliest convenience to take advantage of all that we’ve got to offer in this release!

In the intervening period, flutter team shipped one hotfix release for Flutter 1.17, and plan further updates as required to improve stability and quality. You can find out which bug fixes are included in each hotfix release as well as learn how to ensure that you’re running the latest stable version by going to the relevant wiki page.
