Implement RichEditBox

[YBAZAN]

What would you like to be added:

RichEditBox

Why is this needed:

We need to use this control in our project.

For which Platform:

• iOS
• Android
• WebAssembly
• WebAssembly renderers for Xamarin.Forms
• macOS
• Windows
• Build tasks
• Solution Templates

To be honest, I'm a little worried about those "not yet implemented" controls. I imagine the job it is to migrate them (among all other tasks and functionalities and bugs you have to do as well). However, that means I cannot use my apps properly on Android (or any platform but UWP) until these controls are implemented, right ? And I don't know neither when I will be able to deploy them (it could be in 2 years 😨...)

Have you a roadmap about it ? What's planned for 3.1, 3.2 releases ?
I like Microsoft's approach with the .NET project. They have preview official releases (leading to a nuget package release) and for each release a post in their blog explaining what's new and changed.

I would love to have a section in the documentation giving a general overview of releases, a roadmap with shipping dates and a vision of WinUI coverage progression.

By the way, thank you again for your hard and excellent work on Uno Platform !

RichEditBox is a cpmplex control to port and we dont have an underlying implementation that can easily be reused. It's one of a few controls that will be a real challenge.

As for roadmap, we're actively working on making something public so to ask the community for input/feedback.

Thanks for your patience, team worked on major foundations and control porting velocity should pick up.

Thank you @francoistanguay for the feedback. I’ve seen the milestones and it goes in a right direction, as the community and the adoption grows.

Concerning the RichEditBox, I searched how it could be rendered on Android. Not an esay job, as you said...

Basically I use it as a Markdown editor. But with the coming implementation of WebView.NotifyScript (for 3.1 release he he), I could maybe use a javascript editor as a workaround.

This is by no means feature complete but an alternative would be to leverage any of the existing javascript editors and embed them using a webview (and inline with wasm).
I've got a sample project that illustrates hosting markdown.js and pdf.js in order to view markdown and pdf documents. I haven't thoroughly tested it on every platform but it seems to work well as a way to leverage JS libraries

Duplicate of #81.

@jeromelaban I'm going to re-open as my previous comment is not correct. #81 is for RichTextBlock while this issue is for RichEditBox. They could have similar implementations though.
