Fuel

Sweetly simple dependency injection.

Features

• Zero dependencies. No third party dependencies, not even the standard library. Pure Dart, works outside of Flutter.
• Implicit registration. Dependencies will automatically register as singletons the moment they're injected. No need to explicitly register them all at the start of your program, consequentially making them lazy loaded.
• Minimal implementation. Fits within ~2.5 kilobytes with a dead simple API and documentation, minification not included.
• No build_runner. A simple abstraction that utilizes Dart's type system.

Q&A

• Factories?. fuel does not explicitly provide a method for registering factories. Provide the dependency as is since fuel expects you to not tightly couple dependencies and dependents a la dependency injection.
• Eager loading? Call the use method at the start of your program a la traditional usage of service locators.
• Asynchronous injectors? fuel will not explicitly provide support for asynchronous injectors. Since injectors in fuel are just functions, futures can be resolved within the injector via the .then method.
• Updates? Likely not. The API will intentionally remain small to do one thing, and one thing well; more complex requirements are better served by the get_it package. It is unlikely bugs will occur with how short & simple the implementation of this package is.
• Do I need this? Not necessarily. This package merely provides you with the convenience of having an architectural pattern already implemented for you that you can also implement yourself within a few lines of code.

Installation

# For Flutter projects
flutter pub add fuel

# Otherwise
dart pub add fuel
