dart_depcheck is a command-line tool to check for unused dependencies in Flutter/Dart projects.

Installation 📥

Make sure you have the Dart SDK installed on your machine.

Option 1: Global installation 💻

  1. Install dart_depcheck globally:
dart pub global activate dart_depcheck

# Or locally by cloning the repository and running:
dart pub global activate --source path .
  1. Run the dart_depcheck command in the root of your Flutter/Dart project to check for unused dependencies:

Optionally, you can specify the path to your project using the -p option, add additional folders to search using the -f or --folders option, and exclude packages from the unused dependency check using the -e or --exclude option:

dart_depcheck # This will check the current directory for unused dependencies.
dart_depcheck -p /path/to/project # This will check the specified project path for unused dependencies.
dart_depcheck -f bin,test # This will include the specified additional folders (lib, bin, test) in the search for unused dependencies.
dart_depcheck -e yaml,path # This will exclude the specified packages (yaml, path) from the unused dependency check.

# You can also combine the options:
dart_depcheck -p /path/to/project -f bin,test -e yaml,path

# To display the help message:
dart_depcheck --help

This will check the dependencies declared in the pubspec.yaml file and display a list of both unused dependencies and dev_dependencies found in the project.

Option 2: Add as a Dependency 📦

You can also add dart_depcheck as a dependency in your Dart project and use it programmatically.

Add dart_depcheck to the dependencies section of your pubspec.yaml file:

  dart_depcheck: ^0.0.1

Import the package and use the DependencyChecker method in your code:

import 'package:dart_depcheck/dart_depcheck.dart';

void main() async {
  await DependencyChecker.check();

You can also specify the project path, additional folders to search and packages to exclude:

import 'package:dart_depcheck/dart_depcheck.dart';

void main() async {
  await DependencyChecker.check(
    projectPath: '/path/to/project',
    additionalFolders: ['bin', 'test'],
    excludePackages: ['yaml', 'path'],
