Collection of Flutter lints that we use and follow in Miquido

lint_quido style: miquido lints #

This is collection of Flutter lints that we use and follow in Miquido Software development company.

This is strict, large and robust collection because we strive for high quality code, good practices and we want follow the same coding style in all our mobile apps.

And we just looooove lots of lints. 💙


Getting started #

We tested current configuration with this environment:

environment:
  sdk: ">=2.18.0 <3.0.0"
  flutter: ^3.3.5

so it is required to update your flutter project to meet this conditions.

Installation

Reference this package in your pubspec.yaml in dev_dependencies section.

Until we are not published in pub.dev, reference it like this

dev_dependencies:
  lint_quido:
    git:
      url: https://github.com/miquido/lint_quido.git
      ref: main

or

you can copy content of this file to your analysis_options.yaml. In this approach remember that you need to depend on dart_code_metrics: 4.21.2, and you will need to add that package to your pubspec.yaml as well. Also you will need to visit this repository from time to time to check for changes!

Also if you star this repo, that would be nice.

Usage #

After you add lint_quido package as a dev_dependency, we recommend to copy code from below to analysis_options.yaml file which is in root of your flutter project folder.

include: package:lint_quido/miquido_lints.yaml

analyzer:
  errors:
    # Those are handy, but annoying lints. Remember to change `ignore` to `info` once per two weeks or before app release.
    prefer_const_constructors: ignore
    prefer_const_constructors_in_immutables: ignore

And that is all folks! You are good to go!

Excluding and suppressing rules

If for some reason you don't agree with some linters, or you heavily oppose some approaches you can exclude or suppress lints.

Excluding

To completely exclude rule from linter, modify analysis_options.yaml:

analyzer:
  errors: #linters from flutter sdk
    unawaited_futures: ignore

dart_code_metrics:
  rules-exclude: #linters from dart_code_metrics
    - prefer-last
Suppressing

In code add ignore comments

  • at line level (comment directly above the specific line of code):
// ignore: public_member_api_docs
  • at file level (comment at the top of the file):
// ignore: public_member_api_docs

Commands

To analyze your code in terminal use this commands:

# Default flutter analyze, mandatory to pass!
flutter analyze

# Find unused files in your code! Nice to keep eye on this one.
dart run dart_code_metrics:metrics check-unused-files lib

# Dart metrics analyze, not mandatory to pass!
# Also it calculate total technical debt of your project.
dart run dart_code_metrics:metrics analyze lib

Here you can find documentation about dart metrics command.
