README.md

Example to demonstrate tests for schema migrations.

See test/migration_test.dart on how to use the generated verification code.

Workflow

Schema changes

After adapting a schema and incrementing the schemaVersion in the database, run

dart run drift_dev schema dump lib/database.dart drift_migrations/

Generating test code

Run

dart run drift_dev schema generate drift_migrations/ test/generated/ --data-classes --companions

Since we're using the step-by-step generator to make writing migrations easier, this command is used to generate a helper file in lib/:

dart run drift_dev schema steps drift_migrations/ lib/src/versions.dart
