Migration class abstract

One reversible schema change. Subclass it, implement up and down, and hand instances to a Migrator in the order they should run.

class CreateUsersTable extends Migration {
  @override
  Future<void> up(SchemaBuilder schema) => schema.create('users', (t) {
    t.id();
    t.string('email').unique();
    t.timestamps();
  });

  @override
  Future<void> down(SchemaBuilder schema) => schema.dropIfExists('users');
}
