The base interface for both widgets and themes.
A widget may only support certain framework versions due to breaking API changes, so this property allows the widget/theme to define the framework version that it supports. This version check is not currently enforced, but will be enforced in the future.
You don't need to add this property in your code, this property is added at runtime.
Save the current locale only, but not the default locale.
The default string should be written in manifest.

This should be same as the
_widgetLabel value in translation/default.ts
The name must be unique and same as folder name.
The widget/theme version.
