Migration Validation Flow

The package includes a demo migration validator that creates temporary apps, runs the migration pipeline, and checks whether the migrated apps still analyze and test successfully.

Run both supported migrations

anas validate-migration

Run one source package only

anas validate-migration --from easy_localization
anas validate-migration --from gen_l10n

Write a report

anas validate-migration \
  --report build/migration_validation/report.json \
  --compare benchmark/migration_validation_baseline.json

Refresh the timing baseline

anas validate-migration \
  --report benchmark/migration_validation_baseline.json \
  --compare benchmark/migration_validation_baseline.json \
  --update-baseline

What it validates

For each supported source package, the validator:

1. generates a temporary demo Flutter app
2. runs flutter pub get
3. runs anas convert --from ...
4. runs anas migrate --from ... --apply
5. runs dart run anas_localization:localization_gen
6. runs flutter analyze
7. runs flutter test

It also records per-step timings and total time.

CI behavior

• functional failures should fail CI
• timing regressions over the configured threshold are warnings only
• reports are saved as workflow artifacts
