Simple app using the Flutter SearchDelegate class to show a list of users matching the input search query:

The app uses switchMap & debounce from RxDart for a good user experience, without putting too much load on the server, or compromising bandwidth and battery life on the client.

Simple architecture diagram:

• GitHubSearchAPIWrapper: pulls the data from the GitHub REST API
• GitHubSearchResult: contains the API response data
• GitHubSearchDelegate: shows the search UI with a grid of results
• GitHubSearchService: holds the logic for wiring up the API wrapper with the UI

• RxDart by example: querying the GitHub Search API with switchMap & debounce
