Get in line to high-five @zhitaop and take a selfie 🤳 with him through the new camera control we now have because of him!
Zhitao almost single-handedly did all the work to port CameraView over from Xamarin to .NET MAUI. In fact, its a great story, because the company where he works is a big fan of the .NET MAUI Community Toolkit (and open-source in general) and this is their way to contribute back by donating time to contribute code that they need themselves.
This release is a separate package from the main Toolkit, just like the Windows Maps and MediaElement. We decided to name the package to just Camera so that we can also add other things to this amazing control. But the control itself will still be named CameraView. If you want to install the NuGet, go look for CommunityToolkit.Maui.Camera.
For v1, we tried to stick with the core functionality first and make that work as stable as possible and from there branch out to all the amazing things we can come up with for a camera.
We think you will love this, please let us know!
If you decide to go try it out, maybe the docs will come in handy as well to get you started. Find those here: https://learn.microsoft.com/dotnet/communitytoolkit/maui/views/camera-view
Again, a big thank you to @zhitaop and his company and others who helped make this possible. A big milestone for our little project!
