Improve search functionality

[omeritzics]

Description

To improve usability and align with modern standards, the search functionality in the App Catalogue needs to be more dynamic and intuitive. Users should be able to find apps instantly without unnecessary clicks. Related: #90 (comment).

Key Features

• Real-time Search (Debouncing): Filter the app list automatically as the user types, with a 300ms delay to ensure smooth performance.
• Fuzzy Matching: Search through App Names, Package Names, and Descriptions.
• Search UI Enhancement: * Add a "Clear" (X) button to the search field.
  • Implement a "No results found" placeholder with helpful feedback.
• Focus Management: Automatically focus the search bar when the search page is opened.

Technical Tasks

• Implement a Debounce mechanism for the search input.
• Create a filtering logic that covers multiple metadata fields (Name, ID, Description).
• Update the UI to show/hide the "Clear" button based on input.
• Add an "Empty State" view for searches with zero results.

Is it possible to add search based on about information of app? E.g. There are some key text in about information of app and we can search based on those key texts?

Honestly, this would be a bit complicated to add, since Updatium (and Obtainium) only retrieve the APK file itself.
This is not a "no", but rather "not now". I see the future Updatium well-functioning both as a APK track list and an app store. But we're still not there.

No, not from github. About information which we can add in Updatium app when we add a new app.(screenshot attached)

Oh, now I understand. This would be much easier to implement, I'll take a look into it.
Until then, the Nightly build is now ongoing, and includes some Material Expressive improvements to the UI. What do you think about the new design? Are there areas that can be better?

Yes, the new UI in the 26.2.0 debug APK looks pretty good and clean. I am exploring it and will see if any areas can be improved. There is a bug around the app icon and app details page, but it's a nightly build, so there will be such bugs.

Thank you for your feedback :)
The bug in the app icon should be fixed in the next days
