Description

Firstly, before implementing web support for the plugin. It needs platform separation.

The main package should be platform agnostic. Three different platform-specific packages need to be created instead, along with the platform interface.

So the new package structure should be:

• phone_number (main)
• phone_number_platform_inteface
• phone_number_android
• phone_number_ios
• phone_number_web (Web Support #44)

@deandreamatias I need your help here. You can create those remaining repositories on flutter-form-builder-ecosystem.

Roadmap:

1. Create required subdivision folders
2. Working out platform interface
3. Migrating old platform code to platform-specific repos.
4. Testing (Android, iOS)
5. Merging the changes into main in actual phone_number repo.
6. Publishing (platform-specific -> unlisted packages) (@deandreamatias)
