migrationFailedAndRestoreFailedProtocol method

void migrationFailedAndRestoreFailedProtocol(
  1. T schema
)

Should only be implemented if it is possible to fail a migration and then a subsequent restore. Ex: both migration and restore depend on another service that is down

Implementation

void migrationFailedAndRestoreFailedProtocol(T schema) {
  throw UnimplementedError();
}
