uri_has_not_been_generated

Target of URI hasn't been generated: '{0}'.

The analyzer produces this diagnostic when an import, export, or part directive is found where the URI refers to a file that doesn't exist and the name of the file ends with a pattern that's commonly produced by code generators, such as one of the following:

• .g.dart
• .pb.dart
• .pbenum.dart
• .pbserver.dart
• .pbjson.dart
• .template.dart

If the file lib.g.dart doesn't exist, the following code produces this diagnostic:

import 'lib.g.dart';

If the file is a generated file, then run the generator that generates the file.

If the file isn't a generated file, then check the spelling of the URI or create the file.
