SearchJetpackCompose

Search module with Jetpack compose

Key steps:

• In the Student data class the function interpretInputText define as much pattern as you need for your custom search.
• In MainViewModel 3 main stateFlow: searchInput, isSearching and students list, which are converted to compose state in MainActivity while collecting: collectAsState()
• students list depend on searchInput and _students that's why we use combine operator which will be triggred whenver one of those are changed.
• The logic behind adding .debounce(1000L) is to improve search performance when implementing search with a real remote API: it create a delay until next block is executed, meanwhile if the searchInput change value the previous call/emission (with previous value) is canceled and the new value will be used for search, and by doing this we reduce the API call.
• In MainActivity to be able to get instance of MainViewModel like this: val mainViewModel = viewModel<MainViewModel>() you need first to add the dependency:

  implementation("androidx.lifecycle:lifecycle-viewmodel-compose:2.6.2")
