This directory contains the C# bindings for the Flex library. The bindings are meant to be used by Xamarin projects (iOS, Android, macOS, Forms, etc.).
The best way to get started with Xamarin.Flex is to install the NuGet package:
https://www.nuget.org/packages/Xamarin.Flex
In a Xamarin project, this can done in the Packages folder of your Visual Studio solution.
You may want to build your own version of the bindings, in case you would like to use changes that haven't been released yet, or testing changes you made in your local copy.
The first thing to do is to build the native code for all the platforms that you might need. You can simply run make in the root project directory (you may have to tweak the Makefile according to your environment):
$ (cd ../.. && make)
Now that the native code is built, you can build the C# bindings. Running make in this directory will build the C# code into a DLL file and package it along with the native code to create a NuGet package:
$ make
This should leave you with a Xamarin.Flex.???.nupkg file in this directory that you can add to your Xamarin project. Once added, the API should be available in your project and you should be good to go!
The bindings are fully documented using Mono Documentation XML format.
You can generate the documentation by running make in the docs directory which creates HTML files under the en.html sub-directory.
$ cd docs
$ make
$ open en.html/index.html
The documentation is also available online here:
https://developer.xamarin.com/api/namespace/Xamarin.Flex
You will find under the samples directory a few projects using the bindings. These projects require the Xamarin.Flex NuGet package.
The bindings are covered by tests. The tests specifically cover logic added by the bindings themselves, the native test suite (in the tests directory of the root project) covers the flexbox implementation itself.
$ cd tests
$ make
$ cd tests
$ msbuild
$ bin\x64\Debug\test.exe
