Overview
depend is a lightweight dependency injection package for Flutter that simplifies service initialization and access throughout the widget tree. It enables developers to register and retrieve dependencies with minimal boilerplate, promoting clean architecture and easier testing. The package supports all major platforms—Android, iOS, Web, macOS, Windows, and Linux—and integrates seamlessly into existing Flutter projects via a simple pub add command. With intuitive APIs, depend enhances code maintainability and reduces reliance on global variables or context-heavy patterns.
