😻 Usage

1. Add import_lint as a dev_dependencies in pubspec.yamls.

flutter pub add --dev import_lint

or

dart pub add --dev import_lint

2. You have lints configured in an analysis_options.yaml file at the root of your project.

• target_file_path: Specify a file paths to analyze.
• not_allow_imports: Specify import rules not to allow.
• exclude_imports: Specify exclude import rules.

Example

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: []
        domain_rule:
            target_file_path: "domain/**/*_entity.dart"
            not_allow_imports: ["domain/*_entity.dart"]
            exclude_imports: ["domain/base_entity.dart"]
        package_rule:
            target_file_path: "**/*.dart"
            not_allow_imports: ["package:import_lint/import_lint.dart"]
            exclude_imports: []
        core_package_rule:
            target_file_path: "package:core/**/*.dart"
            not_allow_imports: ["package:module/**/*.dart"]
            exclude_imports: []
        # add custom rules...
