Implementing a Search Debouncer for Efficient Searching in the App

PART OF GTC OPEN SOURCE INTIATIVE

Our Flutter application currently lacks an efficient mechanism for handling search input, resulting in unnecessary API calls or performance issues when users perform frequent or rapid searches. To enhance the user experience and optimize search functionality, we need to implement a Search Debouncer, which will delay and consolidate search requests based on user input. This issue aims to create a reusable Search Debouncer solution for our app.

Key Objectives:

1. Design and implement a Search Debouncer class or utility that can handle search input events and delay the execution of search requests.
2. Integrate the Search Debouncer into the app's search functionality to debounce user input, preventing frequent or unnecessary API calls.
3. Configure the debounce delay based on the application's requirements, balancing between responsiveness and reducing unnecessary network requests.
4. Provide an option to cancel or override a pending search request if the user modifies their input before the debounce delay elapses.
5. Implement proper error handling and feedback when search requests fail or encounter errors.
6. Ensure the Search Debouncer is easily configurable and reusable across different parts of the application.
7. Write unit tests to verify the functionality and reliability of the Search Debouncer.

To successfully complete this issue, the developer should have a solid understanding of Flutter development, event handling, and asynchronous programming. They should be able to create an efficient and reusable Search Debouncer that enhances the search functionality while maintaining a smooth user experience.
