plugins:

copied to clipboard
Basic configuration #
Add configuration to analysis_options.yaml file. You can start with predefined one:
architecture_linter:
excludes:
- "**.g.dart"

lint_severity: warning

layers:
- &infrastructureLayer
name: "Infrastructure"
path: "(infrastructure)"
- &domainLayer
name: "Domain"
path: "(domain)"
- &presentationLayer
name: "Presentation"
path: "(presentation)"
- &useCaseLayer
name: "Domain/UseCases"
path: "(domain/use_cases)"
- &utils
name: "Utils"
path: "(utils)"
- &repository
name: "repository"
path: "(repository)"

layers_config:
- layer: *repository
severity: error

banned_imports:
- layer: *domainLayer
banned:
- *presentationLayer
- *useCaseLayer
- *infrastructureLayer
- layer: *presentationLayer
banned:
- *infrastructureLayer
- layer: *infrastructureLayer
banned:
- *useCaseLayer
- *presentationLayer
- layer: *useCaseLayer
banned:
- *presentationLayer
- *infrastructureLayer

Configuring lint severity: #
To change lint severity for whole plugin add lint_severity entry in analysis_options.yaml under architecture_linter
with one of three values:

info
warning
error

For example:
lint_severity: error
copied to clipboard
You can also configure severity for lower level layer which is under already defined banned layer
For example:
lint_severity: warning

layers:
- &domainLayer
name: "Domain"
path: "(domain)"
- &presentationLayer
name: "Presentation"
path: "(presentation)"
- &repository
name: "repository"
path: "(repository)"

layers_config:
- layer: *repository
severity: error
- layer: *infrastructureLayer
severity: error

banned_imports:
- layer: *presentationLayer
banned:
- *domainLayer
- layer: *infrastructureLayer
# You can also specify severity per layer
severity: info
banned:
- *domainLayer
copied to clipboard
With this configuration, if repository under domain folder has been imported to presentationLayer
the lint would be displayed as error.
An import of any file from domain to infrastructureLayer will result in lint alert of
severity info despite of layers_config setting.
CLI: #
Package also supports CLI, run it with:
$ dart run architecture_linter:analyzer analyze lib

# or for a Flutter package
$ flutter pub run architecture_linter:analyzer analyze lib
copied to clipboard
You can also configure severity for which analyzer will have exit code 2, for example:
# Defaults to warning
$ dart run architecture_linter:analyzer analyze lib --set-exit-on-severity-level=info

copied to clipboard
Then analyzer will exit with code 2 when info or higher level inconsistencies (error, warning) have been found.
