[Proposal] Enhance Get Package with findOrPut Extension

[EngrTAHAR-Noureddine]

Dear Flutter Community,

I'm proposing a new extension for the Get package to enhance its dependency injection capabilities. This extension, findOrPut, simplifies the process of retrieving a dependency from the Get service locator, or creating and registering it if it doesn't already exist.

Here's the proposed extension:

extension AddExt on GetInterface {
  S findOrPut<S>(S dependency, {String? tag}) {
    try {
      S s = GetInstance().find<S>(tag: tag);
      return s;
    } catch (_) {
      S s = GetInstance().put<S>(dependency, tag: tag);
      return s;
    }
  }
}

Benefits:

• Reduced Boilerplate: This extension eliminates the need for repetitive try...catch blocks to handle cases where a dependency might not be found.
• Improved Readability: The code becomes more concise and easier to understand, as the logic for finding or creating a dependency is encapsulated within a single method.
• Enhanced Maintainability: Changes to dependency retrieval or registration logic only need to be updated in one place, improving code maintainability.

Usage Example:

class MyService { 
  // ...
}

void main() {
 Get.findOrPut<MyService>(MyService());  // first Usage
  MyService myService = Get.findOrPut<MyService>(MyService());  // Second Usage
  // ...
}

I believe this extension would be a valuable addition to the Get package, making dependency injection more efficient and elegant for Flutter developers.

I'm eager to hear your feedback and address any concerns you may have. I'm confident that this extension can significantly improve the developer experience within the Flutter ecosystem.

Thank you for your time and consideration.

Sincerely,

Noureddine TAHAR.
