22-33: Consider adding a more comprehensive example of DiagnosticableTreeMixin usage.Since this example class is specifically demonstrating toString customization with Flutter's diagnostic capabilities, it would be helpful to show a more realistic implementation that actually uses the diagnostic features.
@freezed abstract class ToString with _$ToString { ToString._(); @With<DiagnosticableTreeMixin>() factory ToString() = _ToString; @override String toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) { - return 'MyToString()'; + return toStringShort() + + DiagnosticProperties( + 'ToString', + {}, + style: DiagnosticsTreeStyle.singleLine, + minLevel: minLevel, + ).toString(); } }

25-26:✅ Verification successful
Appropriate fix to add
DiagnosticableTreeMixinto support the customtoStringmethod.The addition of the
@With<DiagnosticableTreeMixin>()annotation is necessary for proper functioning when overriding thetoStringmethod with Flutter's diagnostic parameters. This fixes the compilation issue as mentioned in the PR description.Let's verify if this is a common pattern in other freezed examples or classes:
🏁 Script executed:
#!/bin/bash # Looking for similar patterns of using DiagnosticableTreeMixin with toString overrides rg -A 5 -B 5 "toString.*DiagnosticLevel" --glob "*.dart" # Also check for other usages of the @With annotation with DiagnosticableTreeMixin rg "@With<DiagnosticableTreeMixin>" --glob "*.dart"Length of output: 824
DiagnosticableTreeMixin Annotation Verified
The annotation usage in
packages/freezed/example/lib/diagnosticable.dartis correct. The search confirms that the@With<DiagnosticableTreeMixin>()annotation is properly applied to support the customtoStringimplementation with diagnostic parameters, as intended to fix the compilation issue.
- Confirmed presence in the expected file with the appropriate context.
- No conflicting patterns or issues were identified in the repository.
29-32:❓ Verification inconclusive
Confirm that the custom toString implementation works with the mixin.
The overridden
toStringmethod uses Flutter'sDiagnosticLevelparameter, which requires theDiagnosticableTreeMixin. The implementation returns a static string 'MyToString()' which won't use any diagnostic information.Consider whether this example adequately demonstrates proper usage of diagnostic capabilities:
🏁 Script executed:
#!/bin/bash # Check the generated code to see how DiagnosticableTreeMixin is integrated if [ -f "packages/freezed/example/lib/diagnosticable.freezed.dart" ]; then cat "packages/freezed/example/lib/diagnosticable.freezed.dart" | grep -A 20 "_ToString" fi # Look for any related tests that might verify this functionality rg -l "ToString.*test" --glob "*.dart"Length of output: 110
Action Required: Manually Verify DiagnosticableTreeMixin Integration
The executed script did not produce any output, so we cannot conclusively verify that the generated file integrates the
DiagnosticableTreeMixin—nor that the customtoStringproperly leverages Flutter's diagnostic capabilities. Please manually verify the following:
- Confirm that the generated file at
packages/freezed/example/lib/diagnosticable.freezed.dartincludes the intended integration ofDiagnosticableTreeMixin(e.g., by checking for its usage or any related diagnostic code).- Check that the custom
toString({DiagnosticLevel minLevel = DiagnosticLevel.info})inpackages/freezed/example/lib/diagnosticable.dartinteracts with diagnostic features as expected rather than returning a static string.- Verify whether there are test cases that cover this behavior or consider adding tests to ensure the mixin’s functionality is appropriately demonstrated.

Note: this gets it compiling, but doesn't override toString correctly (see CI in #1185) |
