ZenScopeWidget class

A widget that provides a ZenScope to its descendants.

This widget makes a ZenScope available to its subtree, allowing descendant widgets to access controllers and services registered in that scope.

There are two ways to use this widget:

  1. Provide an existing scope using the scope parameter
  2. Create a new scope from a module using the moduleBuilder parameter

Example using an existing scope:

ZenScopeWidget(
  scope: ZenScope(name: 'MyScope'),
  child: MyWidget(),
)

Example using a module:

ZenScopeWidget(
  moduleBuilder: () => MyFeatureModule(),
  scopeName: 'FeatureScope',
  child: MyFeatureScreen(),
)
