`Sms` control - send and receive SMS about flet

hey @hanchenglong001,

Did you see the blog post called Flet adaptive UI and custom controls release?
You can see the implementation of all packages too!

After creating the dart wrapper code, you have to edit the client/lib/main.dart and the client/pubspec.yaml files. Just follow as done with other packages.

On the python side, just create a new file in flet-core/src/flet-core and import the Control class created into the __init__.py file. Just follow as done in other controls like audio.py, video.py ,rive.py, etc...

Once finished, you can test it out as told in contributing docs

Note: this is just for now the moderators seem to be trying to make integration of flutter packages to flet easier, so there might be changes on how to do it.

Can you tell me how to integrate the existing Flutter package into my Flet application?
No examples were found on the official website.
