  • not_allow_imports: Specify import rules not to allow.
  • exclude_imports: Specify exclude import rules.

analyzer:
    plugins:
        - import_lint

import_lint:
    rules:
        use_case_rule:
            target_file_path: "use_case/*_use_case.dart"
            not_allow_imports: ["use_case/*_use_case.dart"]
            exclude_imports: ["use_case/base_use_case.dart"]
        repository_rule:
            target_file_path: "repository/*_repository.dart"
            not_allow_imports:
                [
                    "use_case/*_use_case.dart",
                    "repository/*_repository.dart",
                    "space\ test/*.dart",
                    "repository/sub/**/*.dart",
                ]
            exclude_imports: []
        package_rule:
            target_file_path: "**/*.dart"
            not_allow_imports: ["package:import_lint/import_lint.dart"]
            exclude_imports: []
        # add custom rules...
