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:
- Provide an existing scope using the scope parameter
- 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(),
)

Properties
- child → Widget
-
The child widget to which the scope will be provided.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- moduleBuilder → ZenModule Function()?
-
A function that creates a module to be registered in a new scope.
Use this for feature modules with dependencies.
final
- runtimeType → Type
-

no setterinherited
- scope → ZenScope?
-
An existing scope to provide to descendants.
Use this when you already have a scope instance.
final
- scopeName → String?
-
Optional name for the scope when creating one via moduleBuilder.
Defaults to the module name if not provided.
