# Flutter 1.12.13 release notes

> Release notes for Flutter 1.12.13.



Welcome to Flutter 1.12, our biggest stable release so far!
In this release, we've merged 1,905 Pull Requests
from 188 contributors, including both Googlers and
non-Google contributors! Please see the chart below
for the number of PRs in each release. Over the past year,
the number of PRs has been growing in each release
(except for Flutter 1.9, which was an out-of-band
release to support Catalina). In the recent
[GitHub Octoverse report][],
Flutter is listed as one of the top 3 active repos on GitHub!

As the holiday season is upon us, we would like to express
our sincerest appreciation to our amazing developer community
who believe in Flutter, advocate for Flutter, and contribute to Flutter.
It's been an incredible year for us all! We look forward to
working with you in the years to come.

As always, you can find interesting PRs listed below.
And there are lots of interesting things to mention in this
release, including:

*   Some breaking API changes
*   Some severe issues caught and fixed
*   Web support is now available in the beta channel
*   MacOS support is enabled in the dev channel as of 1.13
*   Improved SDK to add Flutter to existing Android/iOS apps
*   iOS 13 visual refresh including the support for iOS Dark mode
*   Enhanced tooling experiences
*   New widgets and features
*   And more!


## Breaking changes

In general, we want to avoid introducing breaking changes to Flutter,
our plugins, or our packages. However, sometimes it is inevitable
when we need to make our APIs more intuitive.
We have implemented a new process that invites you to submit
tests to help us detect breaking changes.
For more information, see [this post from Ian Hickson][]
on [flutter-announce][] and the
[breaking change policy on the Flutter wiki][].

The following list includes breaking changes in this release.
Please see the related announcements so that you can move
forward with your code.

we have a new set of APIs available for existing
Android plugins to be upgraded to.
If you are currently maintaining an Android plugin.
We encourage you to check the
[Migrating your plugin to the new APIs][] documentation,
and upgrade your plugins accordingly.
