StacSetValue class

A Stac widget that sets values in the application state.

This widget allows you to set multiple key-value pairs in the application's state and optionally render a child widget. It's useful for managing application state through JSON configuration.

StacSetValue(
  values: [
    {"key": "userName", "value": "John Doe"},
    {"key": "isLoggedIn", "value": true},
  ],
  child: StacText(data: 'Welcome!'),
)

{
  "type": "setValue",
  "values": [
    {"key": "userName", "value": "John Doe"},
    {"key": "isLoggedIn", "value": true}
  ],
  "child": {"type": "text", "data": "Welcome!"}
}
