7-20: Good additions for development workflow.The new
test,lint, andformattargets are well-structured with proper.PHONYdeclarations. These will help standardize the development workflow.Regarding the static analysis hints about missing
allandcleantargets: these are common conventions but not strictly required. Consider adding them if you want a standard entry point (all) and cleanup mechanism (clean), but this is optional for a project-specific Makefile.lib/src/capabilities/index.dart (1)

ViewModelCapabilityDelegatecapability to consumers.lib/src/driver_api/ui_driver.dart (2)
11-12: LGTM!The
ViewModelCapabilityDelegatemixin is correctly added toUIDriver, replacing the removedWidgetDisplayStateNotifierimplementation. This aligns well with the new capability-based architecture.
47-56: Well-documented initialization method.The
init()method has clear documentation explaining its purpose and return behavior. This provides a proper lifecycle hook for driver initialization.lib/src/capabilities/view_capability.dart (2)
5-12: LGTM on documentation quality.The mixin documentation clearly explains the purpose, usage context, and expected implementation behavior. This provides excellent guidance for implementers.
13-14: Ensuredriverfield is properly initialized in all implementations of capability delegate mixins.All capability delegate mixins declare
late final UIDriver driver;without an initialization mechanism. Classes mixing inViewModelCapabilityDelegate,FocusCapabilityDelegate,UIControllerCapabilityDelegate, orServerActionExecutionCapabilityDelegatemust explicitly initialize this field (typically via constructor or setter) before any methods depending on it are invoked. Document the initialization contract to prevent runtime errors in concrete implementations.

93-112: Consider using an enum for display state instead of magic integers.The
stateparameter accepts0(not visible) or1(visible). Using magic numbers reduces type safety and code clarity. An enum would make the API more discoverable and prevent invalid values.Based on past review comments, this suggestion has been previously made but not yet addressed.

7-12: LGTM: Successful integration of ViewModelCapabilityDelegate.The addition of
ViewModelCapabilityDelegateto the mixin list successfully migrates UIDriver to the new capability API. The removal ofWidgetDisplayStateNotifier(per the summary) indicates a clean transition away from the deprecated interface.
44-53: Good addition: Explicit initialization method.The new
init()method provides a clear, documented initialization point for UIDriver implementations. The async signature appropriately accommodates setup operations that may involve I/O or other asynchronous work.
55-63: LGTM: Clear deprecation with migration timeline.The deprecation of the
build()method with the message "Will be removed in the next major release" provides users with a clear signal and timeline for migration. This follows good API evolution practices.lib/src/capabilities/scripting_capability.dart (1)
1-1: Remove the unused empty mixin or implement it with documentation.
ScriptingCapabilityis not used anywhere in the codebase. Either remove it if it's not needed, or add a clear doc comment and implementation if it's intended for future use.Likely an incorrect or invalid review comment.

build()method is now properly marked as deprecated. The messages clearly indicate removal in the next major release.Also applies to: 34-34, 38-38, 65-65
47-56: LGTM! Clear initialization hook added.The
init()method provides a well-documented initialization hook for concreteUIDriverimplementations. This is the appropriate place to calllinkDriverfor all capability delegates.
7-12: Ensure each capability delegate'slinkDriveris called separately during initialization.The four capability delegates—
FocusCapabilityDelegate,ServerActionExecutionCapabilityDelegate,UIControllerCapabilityDelegate, andViewModelCapabilityDelegate—each maintain their ownlate finaldriver reference. Due to Dart's mixin method resolution, callinglinkDriver(this)once will only initialize one delegate's driver reference. The other three will remain uninitialized, causingLateInitializationErrorwhen their methods access thedriverproperty.When implementing concrete UIDriver subclasses, ensure that
linkDriver(this)is called on each capability delegate individually, or provide a helper method that initializes all four.lib/src/capabilities/viewmodel_capability.dart (12)
1-5: LGTM: Clean imports.All imports are necessary and properly organized.
6-14: LGTM: Well-documented mixin declaration.The documentation clearly explains the mixin's purpose and responsibilities. Implementing
DriverRefHolderprovides a clean mechanism for driver linkage.
15-22: LGTM: Solid driver management implementation.The use of a private
_driverfield with a protected getter andlinkDrivermethod provides clean encapsulation and addresses concerns about initialization timing. TheDriverRefHolderinterface ensures a consistent pattern across capability delegates.
23-38: LGTM: Well-documented eventStream interface.Clear documentation explaining the expected behavior and usage. The
@mustBeOverriddenannotation with default throw ensures implementers provide concrete implementations.
40-46: LGTM: Clean buildContext interface.Consistent pattern with appropriate documentation.

62-62: Update build() documentation to address nullable return type.The documentation for
build()does not align with its signature. The method returnsWidget?, but the documentation states "Returns: The widget representing the UI" without mentioning the nullable return or explaining whennullmight be returned.Update the documentation to clarify when
nullis returned and how callers should handle it:Suggested documentation improvement
/// Builds the UI. /// /// This method is responsible for building the user interface (UI) based on the /// current state of the UI driver. It creates and returns a widget that represents /// the UI to be rendered on the screen. /// - /// Returns: The widget representing the UI. + /// Returns: The widget representing the UI, or null if the driver is not yet + /// initialized or if there is no UI to display. Callers must handle null returns. Widget? build();
44-53: Clarify the lifecycle order and initialization contract for UIDriver implementations.The abstract
init()method lacks documentation about the expected calling sequence relative to other lifecycle methods. Add explicit guidance for implementers regarding:
- Whether
init()must be called beforebuild()- When driver linkage (capability setup) occurs relative to
init()- The expected order:
init()→build()→dispose()Example documentation clarification:
- "Must be called before
build()to ensure the driver is fully initialized."- "Implementers should perform capability setup and resource initialization in this method."

Document the driver linkage requirement in the new init() method.
The addition of capability mixins (particularly ViewModelCapabilityDelegate) introduces a dependency on the DriverRefHolder pattern, where linkDriver(this) must be called to establish the connection. This requirement is implicit but not documented in the abstract interface.
Since all four capability mixins follow this pattern, implementations should call linkDriver(this) during initialization. Add a documentation note to the init() method or provide a comment explaining that all capability mixins require driver linkage to be established during initialization.
