Feature

max_lines_function_lint allows you to display a warning when one of your functions/methods exceeds a certain number of lines

Installing

max_lines_function_lint is implemented using custom_lint. As such, it uses custom_lint's installation logic.
Long story short:

• Add both max_lines_function_lint and custom_lint to your pubspec.yaml:

  dev_dependencies:
    custom_lint:
    max_lines_function_lint:
  

• Enable custom_lint's plugin in your analysis_options.yaml:

  analyzer:
    plugins:
      - custom_lint
  

• run with the command:

  dart run custom_lint
  

Custom limit

Limit the maximum of line with a custom value (default 30)

analyzer:
  plugins:
    - custom_lint

custom_lint:
  rules:
    - max_lines_function:
      limit: 50
