lib/src/spot/diagnostic_props.dart (1)
- 9-9: The import of
widget_matcher.dartis added, but there's no direct usage of it in the provided code. Ensure that the imported entities are actually used within this file to avoid unnecessary imports.lib/spot.dart (2)
- 46-46: The removal of certain exports, such as
MutliMatchersandWidgetMatcherExtensions, may impact users relying on these entities. Confirm that these removals are intentional and communicated to users to manage potential breaking changes.- 59-65: The addition of
widget_matcher.dartexports introducesMultiWidgetMatcher,MultiWidgetMatcherExtensions,PropertyCheckFailure,WidgetMatcher, andWidgetMatcherExtensions. Ensure that these entities are intended to be public and documented for external use.lib/src/spot/widget_matcher.dart (4)
- 100-102: The
selectorparameter is marked as deprecated in favor ofelementSelector. Ensure that this deprecation is clearly communicated in the documentation and that there is guidance for migration.- 160-175: The method
hasWidgetPropuses asoftCheckHideNullfunction to handle nullability checks. Ensure that this approach aligns with the overall error handling strategy of the testing framework and provides clear feedback to the user in case of assertion failures.- 199-214: Similar to
hasWidgetProp, the methodhasElementPropusessoftCheckHideNullfor nullability checks. Verify that this method's error handling and feedback mechanisms are consistent with the framework's standards.- 244-259: The method
hasRenderObjectPropintroduces type parameters for the render object and its property. Confirm that the usage of generics here is well-documented and that examples are provided to guide users on how to leverage this method effectively.lib/src/spot/snapshot.dart (2)

The removal of
selectors.dartimport needs to be verified for potential impacts on the file's functionality, especially ifselectors.dartcontained entities used withinsnapshot.dart.

The removal of the TODO comment regarding making
WidgetSnapshotimplementWidgetMatcherandMultiWidgetMatchersuggests a design decision was made. Confirm that this decision is documented and that any necessary refactoring or interface adjustments have been completed.lib/src/spot/selectors.dart (9)

The class
Spotis documented as the root of aWidgetSelectorchain but itsselfgetter returnsnull. Ensure this design is intentional and clearly documented, especially regarding how it integrates with the rest of the widget selection framework.

The
@useResultannotation is used correctly to indicate that the result of methods should be used. This is a good practice to prevent unused return values in widget selection methods.

The
@Deprecatedannotation onspotSingle<W>method is used appropriately to guide users towards the preferredspot<W>().atMost(1)usage. Ensure that deprecation timelines and migration paths are clearly communicated to users.

The
spotElement<W>method's reliance on identity comparison for elements is consistent with the approach inspotWidget<W>. This consistency is good, but again, ensure the documentation clearly explains when and why to use this method.

The
spotIconmethod is a useful addition for matchingIconwidgets. Ensure performance considerations are taken into account when matching icons, especially in large widget trees.
- 1-6: > 📝 NOTE
This review was outside the diff hunks, and no overlapping diff hunk was found. Original lines [236-236]
The
spotKey<W>method for matching widgets by key is crucial for certain testing scenarios. Verify that this method correctly handles different types of keys (e.g.,ValueKey,UniqueKey) and document any limitations.

The
_FirstElement,_LastElement, and_ElementAtIndexclasses are internal implementations for thefirst,last, andatIndexmethods. Ensure these implementations are thoroughly tested, especially edge cases like empty candidate lists or out-of-range indexes.

The
QuantitySelectorsandQuantityMatchersextensions provide a powerful way to assert on the quantity of matched widgets. Ensure that the implementation of these methods is optimized for performance, especially in scenarios with large numbers of widgets.

This review was outside the diff hunks, and no overlapping diff hunk was found. Original lines [436-436]
The
RelativeSelectorsextension allows specifying parent and child relationships in widget selection. This is a key feature for complex widget trees. Ensure that the implementation supports nested and deeply nested widget structures efficiently.
