Summary: Pull Request resolved: https://github.com/facebook/yoga/pull/1280 I'm refreshing some of the dependencies of the project, here doing AGP to 8.0.1. I'm also removing the older publishing plugin as we're most likely going to use Gradle's default publishing + another plugin to manage the nexus interactions (the same we use on React Native). I'm also doing some changes on the JDK side: - Bumps the JDK version to 17 as that's required by AGP - Bumps the source/target version to JDK 8. JDK 7 is long deprecated and we're getting a lot of warnings for it on console. Users should be on JDK 11 already by now, but 8 is also good enough.

Yoga 
Yoga is an embeddable and performant flexbox layout engine with bindings for multiple languages.
Building
Yoga's main implementation targets C++ 14 with accompanying build logic in CMake. A wrapper is provided to build the main library and run unit tests.
./unit_tests <Debug|Release>
While not required, this script will use ninja if it is installed for faster builds.
Yoga is additionally part of the vcpkg collection of ports maintained by Microsoft and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.
Adding Tests
Many of Yoga's tests are automatically generated, using HTML fixtures describing node structure. These are rendered in Chrome to generate an expected layout result for the tree. New fixtures can be added to gentest/fixtures.
<div id="my_test" style="width: 100px; height: 100px; align-items: center;">
<div style="width: 50px; height: 50px;"></div>
</div>
To generate new tests from added fixtures:
- Run
bundle installin thegentestdirectory to install dependencies of the test generator. - Run
ruby gentest.rbin thegentestdirectory.
Debugging
Yoga provides a VSCode "launch.json" configuration which allows debugging unit tests. Simply add your breakpoints, and run "Debug C++ Unit tests (lldb)" (or "Debug C++ Unit tests (vsdbg)" on Windows).
